The Latest

Butt weld fittings are one of the most popular connection types in pipeline systems. It has always been required in large quantities in different industries, and especially for the large diameter pipelines.

 

What is Butt Weld Fittings?

Butt weld is to connect pipes or fittings ends by welding. It’s a weldable steel pipe fitting that would allow branching off, allowing for change of direction of flow, attaching auxiliary equipment, or reduce the size of the pipe.

 

In the case of forged steel butt weld fittings, you would find them to be manufactured according to ANSI/ASME B16.9.

 

Also Known By Welded Pipe Fittings

Butt weld fittings would also be referred to as welded pipe fittings. When these would be used in stainless steel and carbon steel, they would be able to offer certain advantages as compared to socket weld and threaded fittings. Whereas socket weld would only be available up to a specific size, you would find butt weld fittings to be available in sizes starting 1/2 inch to 72 inch.

 

Like general category of pipe fittings, Butt weld pipe fittings include:

  • Butt Weld Elbow In 45 Degree Or 90 Degree
  • Butt Weld Tee And Reducing Tee, Reducer, Cap, Cross

 

Butt Weld Elbow

Butt Weld Elbow

Butt weld elbow is to change fluid direction in pipeline systems; it has long radius (LR) and short radius (SR) types, and has different degree covers 45 degree, 90 degree and 180 degree.

 

Butt Weld Tee

Butt Weld Tees

Butt weld tee (equal tee) has a 90 degree branch along with a straight pipe, it will provide a connects for to install an additional equipment to a pipeline. With the tee structural, same sides of the ends could be welded to the pipe, 90 branch was left open for weld another pipe or a device.

 

Butt Weld Reducer

Butt Weld Reducers

Butt weld reducer has concentric reducer and eccentric reducer two types, used for adjust the fluid rate and speed, by welded a large diameter pipe on one end and a smaller diameter pipe on the other end.

 

Common Material Types of Butt Weld Fittings

Same with socket weld fittings, you would now be able to find butt weld fittings to be available as butt weld elbow, tee, out lets (olets), reducers, and caps. In fact, these would be some of the most common type of butt weld fitting and would be specified according to schedule of pipe and nominal pipe fittings.

 

  • Body Material

It includes different body materials of alloy, stainless and carbon steel butt weld fittings. Therefore, it usually uses welded or seamless pipe as the starting material. It could be manufactured by forging, with the help of multiple processes, in order to get the shape of tees and elbows, amongst the other things.

 

  • Stainless Steel Butt Weld Fittings Usually In Thin Thickness

Just like you would find normal pipe to be sold from Schedule 10 to Schedule 160, you would find the case to be same for butt weld fitting as well. In stainless steel, butt weld fittings have been found to be more common. This would be thanks to the cost advantage that it has to offer. Schedule 10 fittings would also be more common in stainless steel fittings.

 

  • Carbon Steel Butt Weld Fittings

Carbon steel butt weld fittings includes body material in ASTM A234 WPB (most commonly) and WPC, MSS-SP-75 WPHY. And thickness usually at schedule 40 steel pipe fittings, STD, or 80, where pressure class ranged with 1500 psi, 2500 psi, 3000 psi, 6000 psi and 9000 psi.

 

  • Alloy Steel Butt Weld Fittings

Alloy steel butt weld material usually in ASTM A234 WP1, WP5, WP9, WP11, WP22, WP91 etc.

 

  • Classified By Dimensions

Butt weld pipe fittings dimensions referred to the pipe dimensions standard ANSI B36.10 and B36.19.

Diameter range: 1”, 2”, 3”, 4”, 6”, 8” and up to 36”.

Thickness range: Schedule 10, schedule 40, schedule 80, XS, XXS and SCH 160

 

Where fitting dimensions of butt weld fittings are concerned, this would consist diameter in NPS and thickness in schedule.

 

Concentric reducer, eccentric reducers, long radius elbow, tees. The primary reason why these fittings would be used in construction projects is because they would play an important part in branching off, changing the direction of flow, or even mechanically joining equipment to the system. With the help of specified pipe schedule, butt weld fittings would be sold in nominal pipe sizes.

Tenoner machines are woodworking machines that are used to produce tenons, projecting wooden members that fit into a mortise. Typically, tenoners are used with a router and equipped with router spindles. As high-production and high-output devices, tenoner woodworking machines may use automatic tool-changers to reduce setup times. Variable-speed router spindles permit the use of small-diameter tools for precision shaping. Tenoners with tool change magazines can hold up to 25 positions per spindle for added flexibility. These tenoning jigs may feature a personal computer (PC) front-end with memory, diagnostics, and a graphical user interface (GUI). Tenoners that use specialized, proprietary, or application-specific technologies are also available.

 

Types of Tenoner Woodworking Machines

There are two basic types of tenoner woodworking machines: single-ended tenoners and double-ended tenoners. Both types of equipment are equipped with multiple motors and several cutterheads. Specifications for the scribing head include horsepower (hp), shaft diameter, shaft length, vertical movement, horizontal movement, and tooling diameter. Although tenoner scribing-heads are optional, they are often used in applications that require a high degree of accuracy. The main cutterheads are equipped with four shear-cut, replaceable knives and two spur cutters. Additional specifications for tenoners include timber capacity with or without fence, maximum tenon length, top-block vertical and horizontal adjustments, table size, and table working weight.

 

Tenoning machines are designed to produce multiple tenons in batch cycles. Outputs may include round tenons, square tenons, and clipped tenons. Typically, tenoner woodworking machines are designed for either high-volume or flexible production. Modular bases and chain tracks allow for not just tenoning, but also for chamfering, drilling, folding, sanding, sizing, and squaring. To minimize problems posed by conventional chain-track systems, tenoners may use needle bearings that are permanently lubricated and permanently sealed. These woodworking machines may also have hardened cars and joining links. Optional features for tenoners may also include automatic in-feed and out-feed systems, and integration with modules that can transfer products to or from the tenoner machine.

Casters are not just two small wheels in the front but extremely important in allowing the rotation of the wheelchair in all directions. The smooth functioning of the casters is a result of many small parts like thread guards, bearings, locks etc. How to select the right ones? Let’s find out.

 

Caster wheels play a vital role in the functionality and life of a wheelchair. While selecting a wheelchair, one should look for durability and comfort along with the right pair of casters.

 

When the casters aren’t checked for their quality, the wheelchairs end up with the tag of not living up to their required operation and durability. Casters add manoeuvrability to the wheelchair as they can swivel in all the directions. The casters are important to enable the maximum functionality of the wheelchair. While selecting a pair of casters for a wheelchair, one should take into consideration the size required and the type of use of the wheelchair (viz. rough uneven surfaces or smooth roads, indoors or outdoors).

 

The wheelchair casters regulate the function of steering and manoeuvring and it is important that only the correct style that suits one’s needs are purchased. Especially in case of shower and commode wheelchair, the uttermost priority of the users should be getting a pair of compatible casters. So far the medical casters are considered to be best suited for shower and commode wheelchair as they often have high load capacities, with low profiles and swivel resistance, to accommodate high patient weight while providing ease of operation over different floor types and through tight spaces. The design and durability of medical casters make them impeccable for use in the bathroom.

 

Advantages of Medical Casters In Shower Wheelchair:

 

Medical casters have a capacity to bear high weight and swivel resistance that help in the easy functionality of the wheelchair. Medical casters come with thread guards, sealed bearing and lock system.

 

  1. Thread Guard:

Thread guards are significant in providing a long life and functionality of the casters. The thread guards are metal or plastic discs fixed in place between the spanner bushing and caster leg to prevent loose threads (hair) from being coiled around the axle.

 

Lint, thread and other soft material have a tendency to work into caster wheel bearing. A caster with thread guard limits this tendency and overcomes this problem. The thread guard does not revolve and thus forces the thread to lie away from the wheel bearing. For a shower and commode wheelchair, a plastic thread guard is recommended. It improves the life of the caster as it avoids corrosion and coiling of hair when used in the bathroom environment.

 

  1. Bearings:

Most caster applications require the wheel to function with a bearing. There are numerous bearing options depending on the wheel design and the application being considered. Open case, metal sealed & rubber sealed. For shower and commode wheelchairs, rubber sealed bearings are recommended as they provide better protection from contamination and remain rust-proof. They enable easy and smooth rotation of the casters as the lubricants don’t get washed away easily.

 

  1. Total Lock:

Total Lock brake locks the wheel and swivels simultaneously. It is essential in a wheelchair while transferring the patient to and from the chair, as it ensures the chair won’t move around. It allows risk-free transfers for the patients as well as for the caregivers. The low angle pedal design makes the foot access comparatively easy for convenient operation and functionality of the wheelchair. A contemporary design features a thermoplastic construction that resists rust and corrosion. The brake design features durability with a thermoplastic pedal and provides a maintenance-free operation.

 

Managing Wheelchair Casters:

 

For the smooth ride of a wheelchair, one must maintain the casters. The worst nightmare of wheelchair user is a wheelchair breakdown. Frequently checking for cracks or damage and visible wear and tear is a must. Ignoring these signs can lead to an unwanted wheelchair breakdown and having to send the wheelchair for repairing.  With the right type and quality of casters and regular maintenance, this can be avoided. Wheelchair casters are easy to replace, they can be maintained either by the users or the caregivers.

 

If you need more choice of medical caster wheels, I recommend you to visit Enjoying Go Co., Ltd. – they are the professional caster wheel manufacturer in Taiwan. You can find kinds of casters including chair casters, design casters, locking casters, compression casters, industrial wheels, and more. Now, welcome to check out their website and feel free to contact with Enjoying Go for more details of medical casters!

With hundreds of commodity and engineering resins available on the market today, the material selection process for plastic injection molding can often seem daunting at first. However, it is much easier to pick a plastic when you look into the overall characteristics that these plastics have to offer.

 

Below are the five popular types of resins used for plastic injection molding:

 

  • ABS

ABS (Acrylonitrile Butadiene Styrene) is used in a wide range of industries, such as manufacturing, automotive, medical, and marine. It is an ideal material for structural applications when impact resistance, strength, and stiffness are required. It is widely used for machining pre-production prototypes since it has excellent dimensional stability and is easy to paint and glue.

 

Characteristics:

  • Structural Strength & Stiffness
  • Chemical-Resistant
  • Excellent High & Low-Temperature Performance
  • Great Electrical Insulation Properties

 

Some factors to consider while using ABS is that molding it at a high temperature improves the gloss and heat resistance of the product whereas molding at a low temperature is where the highest impact resistance and strength are obtained.

 

  • Acetal

Acetal is a high-performance engineering polymer often used for parts that would otherwise be made of metal. All acetal are strong and durable making them apt for mechanical parts like gears and chain links. They are ideal for automotive, and construction applications.

 

Characteristics:

  • Abrasion-Resistant
  • Low Moisture Absorption
  • High Strength & Stiffness
  • Creep Resistant

 

Few things to keep in mind before opting for Acetal. They are affected by strong acids or oxidizing agents but have high resistance to most chemicals.

 

  • Polypropylene

Regarded as one of the lightest and most versatile polymers, Polypropylene (PP) is made from the combination of propylene monomers. It is used in a variety of applications to include packaging for consumer products, household products, plastic parts for various industries including the automotive industry.

 

Characteristics:

  • High Flexural Strength
  • Insulation
  • Low Coefficient Of Friction
  • Low Density
  • Heat-Resistant

 

Polypropylene’s characteristics make it ideal for tough, robust products ranging from protective car bumpers to life-saving medical tools. If you are opting for polypropylene, keep in mind that they are flammable and degraded by UV radiation.

 

  • High Impact Polystyrene

High Impact Polystyrene (HIPS) provides tough, low-cost performance and highly customizable surfaces: It can be printed, glued, bonded, and decorated easily. Due to the versatile nature of this material, they are suitable for applications in the cosmetics, display, food, medical, horticultural, industrial and custom thermoforming markets.

 

Characteristics:

  • High Tensile Strength
  • Electrical Insulation
  • Impact-Resistant
  • Great Dimensional Stability

 

A major advantage is that it can be re-molded over and over again, which makes it environmentally friendly as it can always be recycled.

 

  • Low-Density Polyethylene

As the name suggests, Low-Density Polyethylene (LDPE) has a low density which means it has less mass compared to its volume. It is characterized by its short and long chain branching which gives it good clarity and process ability. LPDE can be found in many consumer goods, electronics, housewares, and medical products.

 

Characteristics:

  • Moisture-Proof
  • Reduced Weight
  • Robust
  • Low Crystallization Capacity

 

Keep in mind that it is difficult to bond with other polymers, and should not be used in harsh weather or high-temperature applications.

 

Each type of plastic has their own properties, and it is extremely important to look at the overall defining characteristics before choosing a plastic for injection molding. If you believe a plastic is falling short of some properties, there is always fine tuning through the use of additives and fillers to get the material properties just right – that’s how you end up with over 85,000 types of plastics.

 

If you want to buy quality plastic resin, I recommend you to visit Great Eastern Resins Industrial Co., Ltd. (GRECO). They are the professional manufacturer of specializing in shoe adhesives and kinds of plastic raw materials.

 

Their PC / ABS blends possess excellent mechanical strength and heat resistance, and makes the product sparkling and shiny to become value-added.

The following will help you identify the common question about sine wave inverter and modified sine wave inverter. Ok, let’s move on.

 

Frequently Asked Questions of Two Types of Sine Wave Inverters

 

  1. What is a Pure Sine Wave Inverter? And What is a Modified Sine Wave Inverter?

 

  • Pure Sine Wave Inverter:

The output voltage of a sine wave inverter has a sine wave-form like the sine wave-form of the mains / utility voltage. In a sine wave, the voltage rises and falls smoothly with a smoothly changing phase angle and also changes its polarity instantly when it crosses 0 Volts.

 

  • Modified Sine-wave Inverter:

In a modified sine wave, the voltage rises and falls abruptly, the phase angle also changes abruptly and it sits at 0 Volts for some time before changing its polarity.

 

  1. What Are The Advantages of Pure Sine Wave Inverters?

  • The output wave-form is a sine-wave with very low harmonic distortion and clean power like utility supplied electricity
  • Inductive loads like microwaves and motors run faster, quieter and cooler
  • Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV, fax and answering machines
  • Prevents crashes in computers, weird print outs and glitches in monitors

 

  1. Which Devices Will Not Function Properly From A Modified Sine Wave Inverter?

Any device that uses a control circuitry that senses the phase (for voltage / speed control) or instantaneous zero voltage crossing (for timing control) will not work properly from a voltage that has a modified sine wave-form. Also, as the modified sine wave is a form of square wave, it is comprised of multiple sine waves of odd harmonics (multiples) of the fundamental frequency of the modified sine wave. For example, a 60 Hz. modified sine wave will consist of sine waves with odd harmonic frequencies of 3rd (180 Hz), 5th (300 Hz.), 7th (420 Hz.) and so on. The high frequency harmonic content in a modified sine wave produces enhanced radio interference, higher heating effect in motors / microwaves and produces overloading due to lowering of the impedance of low frequency filter capacitors / power factor improvement capacitors.

 

Some examples of devices that may not work properly with modified sine wave and may also get damaged are given below:

  • Laser printers, photocopiers, magneto-optical hard drives
  • The built-in clocks in devices such as clock radios, alarm clocks, coffee makers, bread-makers, VCR, microwave ovens etc. may not keep time correctly
  • Output voltage control devices like dimmers, ceiling fan / motor speed control may not work properly (dimming / speed control may not function)
  • Sewing machines with speed / microprocessor control
  • Transformer-less capacitive input powered devices like (i) Razors, flashlights, night-lights, smoke detectors etc. (ii) Re-chargers for battery packs used in hand power tools. These may get damaged. Please check with the manufacturer of these types of devices for suitability
  • Devices that use radio frequency signals carried by the AC distribution wiring
  • Some new furnaces with microprocessor control / Oil burner primary controls
  • High intensity discharge (HID) lamps like Metal Halide lamps. These may get damaged. Please check with the manufacturer of these types of devices for suitability
  • Some fluorescent lamps / light fixtures that have power factor correction capacitors. The inverter may shut down indicating overload

Rigging Your Kayak for Fishing: Rod Holders

On November 27, 2018, in Manufacturer, Sport, by Jasmie K.

Kayaks are great tools to utilize for fishing. Kayaks can help you to explore new fishing areas that receive less fishing pressure and can potentially help you catch more fish.

 

Whether you just purchased your first kayak or are exploring new rigging solutions, this guide will help you to personalize your kayak for the most enjoyable experience possible while out on the water.

 

Rod Holders

The cost of rods and reels can really add up. It is not uncommon for the average angler to pay upwards of $300+ dollars for a single rod and reel combo. Whether or not you are one of those anglers, it is important to protect some of your most valuable tools when it comes to kayak fishing. After all, you cannot kayak fish without a fishing rod even if it is an old cane pole.

 

Flush Mount Rod Holders

You may have bought a kayak that was never intended for kayak fishing. That’s okay because you can easily outfit your kayak to become a new fishing machine. A great way to start is to add a Flush Mount Rod Holder Kit.

 

Flush mount rod holders are the most basic style of rod holder and are usually installed in pairs behind the seat in the transition valley from the cockpit to the tank well. They are often installed at a slight 45° angle so that you may easily access the rear tank well storage of your kayak or use them for trolling. The Flush Mount Rod Holder Kit comes with an integrated mounting surface for a pad eye, included in the kit, so that you may have an attachment point for a rod leash (not include in the kit). If you happen to flip your kayak and have your rods leashed, they will not be lost. We recommend using a rod leash when traversing in your kayak. We’ll go over leashes and other rod insurances in a moment.

 

Rod Holder Extender Kit

If your kayak already has flush mount rod holders, you may find that your reels are a little too close to the water and are getting wet. This often happens to kayak anglers who go through the surf to fish offshore or to kayaks that have a low profile. For kayak anglers who fish saltwater, this is not ideal as the saltwater can have a negative impact on the performance of your reels. One way to remedy this is to use Rod Holder Extenders. These rod holder extenders are a universal accessory that will fit into most flush mount rod holders whether they are molded in the kayak from the factory or deck mounted flush mount rod holders. Rod Holder Extenders elevates your rod 9 inches over the deck of the kayak keeping them high and dry, prolonging the performance and life of your fishing reels.

 

Build A Crate Rod Holders

Most kayak anglers re-purpose milk crates for basic storage on their kayaks. Milk crates are a great way to manage tackle and other items that you need immediate access to, but they lack in options. One of those options is rod storage. The kit comes with all the necessary installation hardware and comes in quantities of 1, 2 or 3 rod holders. Using these styles of rod holders makes it very quick and convenient to load and unload your kayak at the launch because all of your gear is in one easy to carry milk crate. For beginners, it is an easy way to get on the water and start fishing without drilling any holes in your kayak.

 

If you need more information of rod holders and other kayak fishing accessories, I sincerely recommend you to visit BroadPlast Industrial Co. – they are the professional manufacturer of specializing in kayak deck fittings. To get more details of rod holders, welcome to check out their website and feel free to contact with BroadPlast.

When you purchased your lathe, you might not have known just what you were going to do with it or what options were available. Now that you’re gaining some experience, you’re realizing that all of those different chucks and accessories that were available could be quite beneficial for a variety of purposes.

 

However, sifting through the mountains of different parts, chucks, and accessories can overwhelm even the most experienced and harden lathe professional. I’ll guide you through some of the most common and popular accessories that you can choose from for your lathe.

 

What Is The Difference Between Chucks And Accessories?

A lathe chuck is the fitting upon with the wood, metal, or glass that you’ll be working will rest. The chuck is the part of the machine that turns, providing you the opportunity to shape the product in the precise manner that you want.

 

Different chucks will give you different options and opportunities for working the wood or metal (and yes, or the glass). Especially for metal working lathes, chucks can determine the threading spacing for certain projects, allowing you to create the perfect thread for the parts you’re attempting to create, such as bolts, camshafts, or other projects.

 

Accessories offer a breadth of options that can be added to your lathe or used to help enhance the experience, refine the process, or open doors to new opportunities to create even more exciting products using your lathe.

 

Different Choices for Chucks

Some lathe chucks use an integral thread for mounting it to the machine. These tend to be larger machines and are not likely to be used in a residential setting or by a hobbyist. Most other lathes use a back plate for mounting the chuck, which makes it easier to replace and try different chucks for various applications.

 

You can choose from:

  • 2 Jaw chucks
  • 3 Jaw chucks
  • 4 Jaw chucks
  • 6 Jaw chucks
  • Soft Jaw chucks
  • Independent jaw chucks
  • Combination jaw chucks
  • Drawtube actuated lathe chucks

 

The 2 through 6 jaw chucks are used with scroll type lathes and are manual actuated self-centering.

 

An independent 4 jaw chuck is not self-centering, but the individual jaws can be moved independently from one another. These chucks can be used to work on an irregular shaped part, or you can use it to set a piece off center for whatever reason that you would have in doing so.

 

Combination jaw chucks combine the self-centering action of the scroll chuck with independently moving jaws. This adds more flexibility with the ability to have the self-centering benefits. Drawtube actuated lathe chucks are powered using hydraulic or air cylinders to move the drawtube forward or backward. When the drawtube moves, it clamps or unclamps the jaws.

 

Each different type of lathe chucks can perform a wide range of tasks, opening the possibilities of incredible designs and processes. Many of the chucks mentioned here are more than the average beginner lathe worker will need or be able to get the most out of, but each one can be used in many standard lathe machines. The only drawback is that not all of these different types of lathes are available for mini or micro lathes.

 

Now, for the Accessories

There are a staggering number of lathe accessories that you can choose from. The challenge is trying to decide what you want and need. Some of the various lathe accessories that you can choose from are:

 

  • Faceplate
  • Mandrel
  • Lathe Dog
  • Collet
  • Knurling Tools
  • Machine Taper
  • Vertical Slides

 

Now, these are only a small selection, but they are the most commonly sought after and used accessories. I’m sure that, given the time, you’ll find a number of other accessories and turn around and say, ‘Hey, what about this one?’ I can’t write a full-length book about these accessories, so let’s stick with these for now.

 

Faceplate

The faceplate is an important accessory for any lathe because you can affix just about any shape or material to your lathe with the right faceplate. The faceplate will be circular and made of cast iron. It will contain holes that you can use to t-nuts to affix the work piece to it. Once you have the piece attached to the faceplate, you would then use threaded studs of the lathe itself.

 

The faceplate allows you to open up the possibilities for various starting shapes and even the finished products that you will design and create.

 

Mandrel

A mandrel is a clamp that is used to keep pieces of metal and wood in place as the turn on the lathe. There are a wide range of mandrels that you can choose from and it will depend on the type of work as well as the material that you’re working on to determine which one is right for you.

It is also possible to have custom made mandrels if you can’t find one that suits your specific needs. The more work you do with your lathe, the more you’ll realize the importance of mandrels.

 

Collet

A collet is a ring or clamp that is used to affix the work piece to the lathe. These collets are externally threaded onto the lathe and usually have a holding capacity that ranges from zero (0) to seven (7) inches in diameter. They are also designed to hold various shapes, such as circular, square, and hexagonal.

 

Knurling Tools

When you want to press a specific pattern or shape into a work piece in order to guarantee its usability, such as grip patterns for hammers and other tools, you’ll want to use a knurling tool. A rubber mallet is a good example of a tool that has grooved edges to benefit the gripping pattern and this is accomplished by using knurling tools.

Knurling tools are used in conjunction with other lathing tools and should never be considered a replacement of other tools in the process of creating objects with the lathe.

 

Machine Taper

When you want to bind other tools to the lathe’s spindle, you will be using a machine taper. These accessories are popular because they tend to be inexpensive and easy to install. They provide you with a range of options and flexibility to be able to hold various tool bits in place.

 

Vertical Slides

When you want to mill on a lathe, you’ll likely want to use a vertical slide. The vertical slide is connected to a cross slide by using a clamp. Both sides are then attached on a bracket and then to the steel plate of the lathe. With vertical slides, you can cut bevel gears. This can mean that you can mill at an angle.

 

Hopefully this list provides you with a starting point to determining which chucks and lathe accessories to choose from for your wonderful lathing experience.

 

If you need more choice and information of lathe chucks, welcome to visit Chandox Precision Industrial Co., Ltd. – they are the professional manufacturer of specializing in power chucks, scroll chucks, super thin chucks, and DIN chucks. To get more information of chucks, please do not hesitate to contact with Chandox.

Once you’ve decided it’s time for a wheel upgrade, how do you know how to select the best bicycle wheel sets? It’s actually pretty straightforward. You already know what bike they’re for, so simply check the label on the tire to find the size. Write that down. That’s the tire size but also the wheel size and it’s the starting point for getting the right wheels. If you’re not sure you can also just ride by the shop and we’ll take a look and tell you.

 

Next think about what you want these new wheels to do for you. Maybe you’re replacing old, bent wheels and looking for a set that’ll hold up better to the way you ride. You could be looking for an easier ride from some lighter, better-designed wheels. Or, it could be a second set of “event” wheels to give you an advantage on certain types of courses, or race wheels to replace your heavier, slower training wheels on the big day. If you can tell us what you’re looking for in wheels we can point you toward a perfect pair.

 

Options and Tips On Deciding

Following are some of the common features found on today’s road, tri and mountain wheels, and some guidelines to help you determine what’s best for you, your bicycle and your riding.

 

  • Wheel Types

Obviously, there are wheels for the dirt and different wheels for the road so that’s one starting point. If you’re looking at off-road wheels you decide, based on your bike, whether they’re disc-brake specific or ready for rim brakes. The difference is that wheels for discs have hubs that accept the rotors (what the disc brakes grab), and usually have rims without a true braking surface, which saves weight at the rim.

 

Rim-brake wheels don’t have any provision for attaching rotors and feature rim sides made to withstand the wear and tear of rim brakes. Note that if you need wheels to use on two bikes, one with discs, one with rim brakes, you can find those too. They’ll have a rim made for braking and a hub setup to accept rotors.

 

When it comes to wheels for the road, there are all-around models made to deliver excellent ride quality and durability that work great for upgrading an old pair. There are also models designed to give you some free speed according to how you use them. For example there are climbing wheels that are built lighter for easier ascending, aero wheels practically invisible to the wind and all-around road wheels that combine lightness, aerodynamics and a compliant ride.

 

  • Tube or Tubeless

Another choice is whether to get dedicated “tubeless” wheels or standard models. Tubeless means that the rim is made to provide an airtight seal for use with tubeless tires. This is important since you run tubeless tires without inner tubes, which allows running lower pressures for a smoother ride and more traction and control.

 

It’s possible with a conversion kit to install tubeless tires on standard wheels, however, getting the dedicated wheels made for tubeless means easier tire installation and no need for the special conversion rim strips. So, if you enjoy riding tubeless on the pavement or dirt, you should consider upgrading to tubeless wheels. Note that these wheels all accept standard tires with tubes too.

 

  • Tubular Wheels

If you race the road you might want to consider “tubular” wheels, which are the lightest available and most unusual. They require special tires called “tubulars” or “sew-ups” (because the tire is actually sewn together around the tube). These tires have truly round profiles and they are installed by gluing them to the rim. Proponents of this design love the quickness and suppleness of these featherweight, round-profile tires and don’t mind the more difficult mounting procedure.

 

  • Rim Shape

The shape of the rim has a lot to do with how the wheel rides. The stiffer the rim the more you feel the road and trail. And, the more triangulated and deep (tall) a rim is, the more rigid the ride. Most of the time, on smooth surfaces you’ll notice stiffness less than on rougher ones. And, stiffness is a good thing for racing and hammering because more of your power makes it to the road.

 

If you’re looking for slippery wheels for an advantage racing triathlons or time trials, or even for getting maximum rest sitting in the pack at your road races and then sprinting faster for the line, look at wheels with deep-section rims, which can be as tall as 90mm or more. For lighter weight and better handling in crosswinds, check out wheels with smaller profiles like 28mm.

 

Besides how deep the rim is, the width makes a difference too. Wider rims (about 23mm) tend to offer a nicer ride and more durability since they spread the tire sides allowing more air and flotation. Meanwhile, narrower (usually 19mm) means more aero advantages and lighter weight.

 

  • Hubs

Wheels spin on the hubs, which are the component at the center of the wheel where the spokes originate. They have bearings and axles inside, and on the drivetrain side either threads for cogs or a “freehub,” that the cluster of gears (called the “cassette”) mounts on. Cassettes are sold separately.

Air blow guns attach to air lines for the manual actuation and/or control of air discharge. They are used primarily for:

 

  • Debris Removal and Purging
  • Non-Contact Part Cleaning and Drying
  • General Laboratory or Industrial Applications

 

Most air blow guns are made of plastic or metal and include an ergonomic grip or handle. A steady stream of compressed air is delivered through a sturdy metallic nozzle. Air blow guns that are equipped with an internal fail-safe pressure mechanism shut off automatically if the gun is dropped or the lip is blocked. Integral pressure relief valves are used to blow off excess pressure before discharge. In the United States, products that meet or exceed standards from the Occupational Safety and Health Administration (OSHA) are commonly available. Typically, manufacturers indicate whether products are suitable for high volume applications, or include a threaded discharge port or vacuum attachment.

 

Specifications

Specifications for air blow guns include pressure capacity and airline connection type. Pressure capacity, or maximum rated pressure, is rated at the air inlet and measured in pounds per square inch (psi). Many types of airline connectors are available. Quick-release connectors contain fittings that are attached internally. By contrast, push-on connectors include barbed ferrules. Air blow guns use several types of national pipe thread (NPT) connectors, most of which are inch-based and female. Important NPT measurements include threads per inch (TPI) and outside diameter (OD):

 

  • 1/8 in. NPT connectors have 27 TPI and an OD of 0.405 in.
  • 1/4 in. NPT connectors have 18 TPI and an OD of 0.540 in.
  • 3/8 in. NPT connectors also have 18 TPI, but an OD of 0.675 in.
  • 1/2 in. connectors have 14 TPI and an OD of 0.840 in.

 

#10-32 NPT threads are also available. Air line connections that can swivel or pivot are suitable for applications that require versatile positioning.

 

Types

Air blow guns vary in terms of nozzle type and actuation style. Standard safety nozzles are suitable for general-purpose applications. Small-diameter nozzles can be inserted into tight openings. Nozzles with rubber tips prevent the marring of surfaces while nozzles with flexible tips can be guided directly to the application point. Air blow guns with extended, straight nozzles provide longer reach. Devices with extended, angled nozzles are designed for use in difficult-to-reach locations. Venturi nozzles contain small holes that allow the discharge to draw ambient air to increase the airflow. Air screens are often used to minimize particle blowback. In terms of actuation, most air blow guns include a discharge lever that is in-line with the air hose and actuated by the thumb. Pistol or trigger-style devices are also available. With these devices, the actuator is located at a right-angle to the air supply hose and incorporates an ergonomic handle. Button-actuated air blow guns are also available.
