What are Forged Pipe Fittings?

Posted on by

Introduction:

 

Forged Pipe Fittings (Thread Fittings and Socket Weld Fittings) are made in accordance to ASME (American Society of Mechanical Engineers) B16.11, MSS-SP-79\ 83\ 95\97 and BS3799 standards, and are used to connect nominal bore schedule pipes and pipelines. The applications range from chemical, petrochemical, power generation and OEM manufacturing industry as well other applications where vibration, high pressure or extremely corrosive conditions exist.

 

Material:

 

Forged pipe fittings are generally available in two materials: Carbon Steel (ASTM A105 material spec), and Stainless Steel SS316 (ASTM A182 material spec). The surface of carbon steel A105 forged pipe fittings may be further reinforced against corrosion through galvanizing. This is an optional add-on which customers may include at an additional cost.

 

Pressure Rating and Size Range:

 

Fittings come in a variety of classes and material grades for any application. The fittings are available in 2000lbs, 3000lbs, 6000lbs, and 9000lbs. Although class 2,000 and 9,000 fittings exist, these are rarely used and class 3,000 and 6,000 remain the more common class of fittings used. Sizes of forged fittings typically range from 1/8” (DN6) up to 4” (DN100). And reducing sizes are available for common parts like couplings, tees, hex bushings and nipples.

 

Connection Types:

 

Class 3,000 and 6,000 forged pipe fittings comes in two types of connection: Socket Weld, or Threaded. NPT (National Pipe Thread) is the most common thread type although BSPP (British Standard Pipe Parallel thread) is also being available for certain parts like Full Couplings, Hex Bushings and Hex Nipples. Socket weld connection is significantly more popular than threaded since most applications call for completely sealing off a line and eliminating all possibility of leakage.

 

The fittings are normally produced with the same connection for all sides of the same fitting. That means, a socket weld fitting will have socket weld connection on all sides. Should different connection ends be required, additional machining could be possible but at a higher cost and a longer lead time.

 

Brands of Forged Fittings:

 

A highly recommended manufacturer for forged pipe fittings is Wellgrow Industries Corp... Wellgrow was established in 1987 in Taiwan, and has been well-recognized among customers worldwide for excellence in its quality and services.

What’s the Difference between a Floor Nailer & Flooring Stapler?

Posted on by

So you are interested in replacing your hardwood floors, but you don’t know which tool will work best for the job? If you look for a flooring tool, you will see there are floor nailers and flooring staplers. Both tools look similar and cost the same, but which one is the one you need?

 

The answer is, either tool can work for you, but let’s explore some of the differences between a floor nailer and flooring stapler, to give you the most informed decision possible:

 

First, let’s look at each of the tools. Floor nailers are available in two variations, manual or pneumatic (air powered). You might hear a contractor refer to this tool as a flooring cleat nailer, as it most often takes cleat nails for fastening. A manual flooring nailer will require additional muscle, as it relies solely on its user’s strength. On the other hand, pneumatic floor nailers assist the user by providing additional force, when inserting a nail. Either of these tools will require a user to hit the driver head when inserting a cleat. The amount of pressure required depends on the density of the wood being installed. A thicker wood will require longer cleats, which also calls for additional force to drive the fastener.

 

Flooring Staplers are also available in manual or pneumatic variations, although manual floor staplers are typically not preferred in the construction trade. As you can see on Nail Gun Depot, electric staplers are also an option, depending on the source of power that you prefer – although pneumatic is by far the most common offering. A hardwood stapler anchors the flooring planks to the sub-floor, driving staples into the tongue of a wood plank.

 

Now that we know the tools available, let’s look at the fasteners that make the difference. As you saw above, the tools operate similarly, which means that the difference primarily lies in the fastener itself. It all boils down to nails versus staples. [Also note that you should not switch between nails and staples when installing a floor – whichever fastener you start with should be the only one used throughout the entire project.]

 

A flooring nail, or cleat, is typically offered in either “L” head or “T” head variation – check and see which variation your nail gun requires. A cleat nail offers a sharp, rigid body to grip the sub-floor firmly. It also features a smooth portion of its body, which allows for seasonal expansion and contraction of the flooring. Typically, cleat nails are available in 16 or 18 gauge – although 20 gauges are also available for certain applications. The more durable option of the two, the drawback to cleats is their cost – compared to the cost of staples.

 

Floor staples provide two-pronged fastening for hardwood flooring. Flooring staples actually provide a stronger initial grip than cleats, but do not hold as firmly when the floor expands and contracts – which can eventually lead to creaking. Another drawback to staples, they can split the tongue of flooring – especially when the plank is less than 3/4″ thick. Because staples are less costly to manufacture, they are typically the more cost-effective flooring fastener, when looking at cleats versus staples. However, you also have to consider the long-term durability of your flooring installation, when selecting between staples and nails.

 

Regardless of the flooring nailer or stapler you choose to use, it is imperative that you understand your tools prior to using. Applying too much pressure can damage your floor, while applying too little pressure can cause cleats or staples to only be driven partially, resulting in each neighboring plank to not form a tight fit, ruining the entire project.

How Do Industries Benefit From Using a Milling Chuck?

Posted on by

A milling chuck is a small piece of metal that connects the cutting tool to the machine. Many industries make use of clamps to hold onto interchangeable tools or drill bits. In the metalworking industry, though, special collars are needed to secure the heavy duty cutting edges used in metal machining. The most common clamp used in metalworking is the collet, or an unusually shaped collar that tapers into a cone at one end. Its unique design enables it to handle a large number of tool sizes and some models can accommodate square or irregularly shaped tools.

 

Compared to other processing machines, metalworking devices are designed a little differently. In most setups, like with a standard power drill, the clamp rotates with the cutting tool or bit while the device remains stationary. A milling chuck is designed to remain in place while the machine itself provides the rotation for the cutting tool. This requires a specially-designed clamp that can handle these unique working conditions. Metalworking, in most cases, must be much more precise than simple drilling, and collets provide this extra precision.

 

This is because the collet is built with a metalworking machine in mind. Metalworking devices are compatible with a number of clamps, but many of them may produce runoff or result in a sloppy cut. Collets are the ideal milling chucks, because they align the cutting edge with the machine better. The improved stability is produced through the collet’s design. Most clamps aren’t tapered on one end and use a series of gripping jaws to grab a tool. A collet, though, grabs the tools much more tightly. Before starting the machine, the cutting tool is placed inside the collet, which can be secured loosely. This grip is enough to hold the tool in place, but it will not provide a stable cut when the machine is in operation. However, once the collet is placed inside the metalworking device, the machine exerts additional force on the clamp, which creates a tighter grip on the tool. Inside the collet, the inner contact surface spins with the cutting tool, resulting in smooth mechanical energy transfer from the machine to the tool.

 

The tapered, conical edge compresses slightly when the milling chuck is tightened into place once inside the metalworking machine. This creates great static friction with the cutting tool, resulting in an extremely tight fit. A stable tool is the best tool when trying to make precision alterations to a piece of metal.

 

Collets and other clamps can be found in a huge number of sizes and designs. The most common designs are the R8, which are built for manual mills, and the 5C, which are designed for lathes. A milling chuck can be sized for tools less than an inch in diameter to pieces several inches wide. No matter the size, the clamping principle is the same. Collets that are made for irregularly shaped tools are known as emergency collets, or e-collets.

 

Precision and stability are the two most important things to keep in mind when working with metal. Without these, the machine will wear down faster, damage product, and cause a major safety hazard. For this reason, it’s smart to invest in clamps specifically made for metalworking machines.

The Secrets of Canning Machines

Posted on by

Canned foods are something that almost no one is willing to live without. Ever since the manufacturing of canned foods began in the late 1800’s, people have been relying on them as a way to keep vegetables and fruits for longer periods of time. The invention of the canning machine helped revolutionize this idea making canned foods available on a large scale.

 

Canning machines took traditional canning from the kitchen to the factory. Instead of using glass canning jars, canning machines typically used aluminum or metal cans to can food for lasting freshness. They are made to withstand canning multiple cans throughout the day without the user having to stop the process to add water to a canning pot. Instead, this machine and others each carry out a process similar to the processors completed within a pressure canning pot.

 

Canning machines work in stages with each stage corresponding to a step that is carried out within a canning pot. There is a part of the machine that fills the can while another part of the machine seals a can. Afterwards, another part of the canning machine uses heat and pressure to force excess air from the cans prior to a permanent seal being applied to the cans.

 

There are 3 specific pieces that belong to the canning machine. They are:

 

  • The Seamer
  • The Filler
  • The Labeler

 

There are various types of canning machines available on the market today. The type of machine that you buy depends are different factors; amount to be canned, size of the cans, type of food being canned. Although there are some canning machines that can produce canned foods in a variety of sizes, these are more expensive and more prone to breaking down. This is usually the result of canning a variety of sizes throughout the day.

 

Because they are put under stress and force every day, canning machines tend to be made of reinforced steel making them extremely heavy. This also helps in supporting the machine by providing structural strength that can be used on a long term basis.

 

Not all canning machines only use metal cans, and there are some using glass jars as well. These machines are made especially for working with glass and shouldn’t be used with metal cans.

 

Most canning machines are controlled by computers; however, there those which are operated by 2 or more people. These canning machine operators are in control of each aspect of the machine. Training on these machines can take up to 6 months depending on how much time a company is willing to spend on training.

 

Canning machines can be bought by companies and by individuals. However, they are generally more practical for use in a factory setting because of the size and weight. The average canning machine weighs in excess of 300 pounds. There are also better suited for a factory because of the speed of output which increases profit while lowering cost.

 

SHIN I Machinery Works Co., Ltd. is a high quality Food Canning Machines manufacturer in the industry. In food canning machines series, we provide automatic seamer and automatic filler for customers.

Fuel Injector Cleaner – Tip for Saving Money

Posted on by

Fuel injection cleaner or fuel injector cleaner is one of those often missed steps in tuneups for cars, trucks, and other automobiles. Because of the fact that it can get a little pricey to disassemble and replace or clean a fuel injection system, it’s often glossed over during regular tuneups. Either that, or a shop will charge you WAY TOO MUCH MONEY just to put an additive fuel injector cleaner into a tank of gas for you, when all you have to do is just buy a bottle and pour it in a full tank of gas yourself.

 

Clean fuel injectors are a definite must in the way of fuel economy, emissions, and peak engine performance. When fuel injectors are dirty, they can’t deliver the correct spray required for combustion, and as a result, fuel economy and engine performance suffers. This, in the long run, can be costly or can even begin to cause symptoms like a rough idle or misfires. That’s why I heavily recommend fuel injection cleaner. The reason I recommend fuel injector cleaner is because it’s one of those simple things a person can do without having to replace any parts or any under the hood work. Normally in a tuneup, lots of things get replaced, things like spark plugs, distributor caps, belts, and fluids. But with fuel injectors, running an additive through a tank of gas every once in awhile will definitely do the trick.

 

Over time, all fuel injectors will become clogged. This happens because the deposits come from the gasoline itself. Gasoline is a compound mixture of hydrocarbons, and includes waxy, heavy chemicals known as oilfins, which yield a lot of energy when burned. As long as a car is running, the fuel injectors and engine runs efficiently. The clogging occurs when the engine is shut off, and a process known as heat soak occurs. Residue of fuel in the injector nozzles begins to evaporate, and it leaves the oilfins behind, which don’t evaporate and some of which don’t get washed away, but instead get baked into hard varnish deposits, which ultimately will clog the injectors.

 

Newer injectors are more resistant than the old ones to this kind of clogging, and additives are added to gasoline to try and dissolve some of these buildups. But cars that make mostly short trips are still especially susceptible to fuel injection clogging, and every injector will ultimately become clogged over time. If the fuel injectors are never cleaned, as the car ages you’ll start to notice that your car shakes a bit while idling and eventually it will either stall or misfire, and all the while your fuel economy and engine performance will suffer. I was just in a car the other day that suffered from a very rough idle, and the driver had to keep a little pressure on the gas petal while stopped to keep the car from stalling.

 

There are a wide variety of fuel injector cleaners, one of the most common being gasoline itself! Cheap gasoline is often lacking in the additives that breakdown clogging and, over the long haul, can cost you more money than it saves. The best tip for keeping your injectors clean is to not buy cheap gas. This however, is only a preventative measure. My guess is that for people reading this article, it’s because your fuel injectors are already partially clogged and are causing problems to your engine performance. If that’s the case, then you still have quite a few options. There are many cheap fuel injection cleaners that you can add to your gasoline which will act like drano on a sink pipe and will dissolve many of the clogs in your injectors. When used semi-regularly (once every few months) it will keep your injectors nice and clean.

 

But this may not be enough for some engines. Older engines already experiencing heavy problems may need a bigger hand. To do this, you might actually need a fuel injection cleaner kit that lets you disassemble the fuel injection system and clean it. This, however, isn’t always a possibility, and some fuel injectors are delicate and difficult to tamper with. Before trying this, I would definitely recommend running a bottle of fuel injection cleaner additive or two through a tank of gas and see if that helps at all. It’s cheap and effective.

We not only offer fuel injector cleaner but also manufacture motorcycle lubricants, agricultural machinery oil, heavy duty machinery oil and more.

What You Need To Know About Diamond Grinding Wheels

Posted on by

Do you know how diamond wheels are classified?

Diamond wheels are actually classified according to shape, concentration, bond, and grit size. These wheels are used in various grinding and abrasive machining operations. Consequently, diamond grinding wheels are used in grinding machines. In any machining or grinding process, it is always important to use the appropriate grinding wheel.

 

One of the most widely used grinding wheels today is the diamond and CBN wheels. These come in several types including resin, vitrified, metal, and electro-plated. The most common among these types is the resin wheels. These are used in most tool room and production applications. On the other hand, the vitrified and metal types are newer bond types and are used in specific applications. These are rare and are more expensive. Moreover, these are usually custom made order items. However, electro-plated wheels are typically found in cut-off wheels and low demanding abrasive grinding such as that for plastics.

 

It is very important to know the different types of diamond grinding wheels and their applications because each of these types is particularly used on specific applications only. Moreover, if you are not using the appropriate wheel type, grinding operations may not be done effectively. Thus, before embarking on any grinding operations, it is essential to determine the type of material to be worked on, and the type of grinding wheel as well.

 

Diamond and CBN grinding wheels are used in a variety of processes and materials. However, diamond wheels are used strictly on carbides while CBN is used on steels. In some cases though, there are some manufacturers that produce a special grit that can be used on both carbides and steels.

 

The three types of diamond grinding wheels that are available in the market are synthetic diamond, cubic boron nitride (CBN), and alumina-zirconia. Among these three types, the synthetic diamond is the hardest, while alumina-zirconia is the softest. In selecting the particular type of wheel, there are some important factors to consider.

 

First and foremost, it is essential to determine the hardness of the item you will be grinding. You should always remember that CBN is most advisable for iron or steel. If the metal is nonferrous though, and a large amount of metal must be removed, a synthetic diamond blade is the most appropriate wheel to use. For soft metals, alumina-zirconia should be used.

 

Second, look at the nomenclature plate on the grinding apparatus. The speed rating in meters per second is very important in ensuring that the bond of the diamond grit will not separate or disintegrate when used on the grinding apparatus.

 

Third, determine if the grinding will be done wet or dry. A wet diamond grinding wheel is used for precision cutting while a dry diamond grinding wheel is used for moderate grinding purposes.

 

Finally, select the coarseness of the wheel according to the amount of metal that will be removed. A coarse grit is most appropriate for fast cutting while a fine grit is used for a finish quality cut.

Applications and Overview about Fiberglass Cloth

Posted on by

There are a variety of applications for industrial fabrics when weight, strength, and durability are important, and one common solution to these needs is fiberglass cloth. Fiberglass cloth is a strong and durable woven textile used mainly for industrial, non-apparel applications. Its unique set of valuable properties makes it ideal for many industrial uses, such as for the interiors of circuit boards and conveyor belts.

 

Fiberglass cloth is woven in various configurations from four basic weave patterns, called plain, leno, satin, and basket. It is sold in rolls that range in length from 150 feet (45 meters) to 9,000 feet (2740 meters), and in many different widths. It also offers a wide choice of controlled properties depending on the industry it will be used in.

 

Fiberglass clothes have numerous applications as thermal insulation, electrical insulation in the electronics industry, and even as a component in armor plating on U.S. Military vehicles, helmets, and aircraft carrier decks. Light-weight cloths also provide a smooth finish and are ideal for producing a waterproof layer over wood or other surfaces, such as are needed in boat repair and other marine applications.

 

Perhaps the most notable quality of fiberglass cloth itself is its high tolerance of extreme heat. It not only dissipates radiant heat with remarkable efficiency, but some types of cloth can withstand temperatures of up to 3000 degrees Fahrenheit (1648 degrees C) for as long as a minute. Another notable attribute of fiberglass fabric is its high tensile strength. At a much lower weight and cost, it has a greater tensile strength than steel wire of similar diameter. Also, fiberglass cloth is composed of inorganic materials, making it impervious to damage from sunlight, bacteria, or fungus of any kind.

 

Glass fibers are known to produce fabrics with excellent dimensional stability as well, meaning that fiberglass fabric stretches only very minimally under stress- usually about three percent or less. Like glass itself, fiberglass is highly resistant to most harsh industrial chemicals. Oddly enough, despite its resilience and resistance to almost every possible type of industrial hazard, it is important that fiberglass cloth be rolled onto a tube for shipment, and not folded, regardless of how large or small the order may be. Folding it for shipment can damage the cloth where it is creased. If this one precaution is followed, the structural integrity of the fabric will be preserved to provide strength or protection in whatever context it is needed for.

 

Taiwan Electric Insulator Co. Ltd. (TEI) is a world leading manufacturer of composite fabrics and fiberglass cloth, with the technology, knowledge and ability to produce the highest grade products to specific customers’ needs and requirements. If you are interested in or need further information about fiberglass cloth, welcome to visit our website and feel free to contact TEI to obtain more details!

What is a GPS Antenna?

Posted on by

A GPS antenna is a device that helps boost the reception signal to a GPS unit, whether it is a standalone unit or an embedded unit. Often a GPS antenna is used in a situation where the GPS unit itself is somehow removed from a line of sight to the sky, as in a car, to help the GPS “see” the sky without having to be moved. GPS antennae may be purchased for a range of budgets, or cheaper home versions can be made with fairly common components.

 

GPS, or the Global Positioning System, is a satellite system originally developed by the United States Department of Defense. It utilizes more than two dozen satellites orbiting the Earth to allow receivers on the ground or in the sky to tell exactly where they are, by receiving heads off of multiple satellites. Using this location, devices can detect not just latitude and longitude, but also altitude, and even heading and speed. For years, GPS was reserved for military use in the United States, but following a directive by President Reagan in 1983 it became open for civilian use.

 

Civilian GPS contains certain restrictions, imposed by the US government to make sure hostile forces don’t use the technology in missiles. As a result, consumer GPS isn’t capable of operating when moving at more than 515 m/s at more than 60,000 feet (18 km). Throughout the eighties and early nineties GPS was used primarily in commercial avenues, such as on fishing boats, in airplanes, or for geographic surveying. In the late nineties it began gaining popularity for consumers for hiking or for driving, and by the new millennium cars were being equipped with built-in GPS to give driving directions, and cell phones began having included GPS for directions and location.

 

A GPS unit has a built in antenna, which is usually quite small and located inside of the unit. While this will likely function in ideal circumstances, such as when in a desert moving at slow speeds or staying still, it may not work as well as one would like in more trying circumstances. A GPS unit likes to have a clear, unobstructed view of the sky, to best receive the microwave signals that allow it to communicate with satellites. For GPS units inside of cars, this can be problematic, so often an external GPS antenna will be used, mounted to the outside of the car with a magnet, and connected to the unit itself by a cable.

 

In situations such as heavy canopy cover while hiking, the small GPS antennas built into a consumer unit also may not be able to ideally communicate with the satellites. In this case, a larger, more advanced GPS antenna helps the unit overcome the environmental challenges, to give a clear signal. Similarly, moving at high velocities can overwhelm a smaller, less sophisticated antenna, and an external device can boost the signal.

 

There are a number of different types of GPS antenna, with the patch and Quad Helix styles being the most popular. Both are roughly equal in efficacy, although many people find the quad helix to have a slight bit more sensitivity. Other types of antennae include microstrips, of which the patch is one configuration, planar rings, and spiral helices.

 

Established in 1996, Cirocomm is an outstanding manufacturer of GPS antenna in the industry. We also provide various antenna series, including dielectric filter, Glonass, WIFI, GSM, NFC antenna series and more.

Basic Information of CNC Rotary Table

Posted on by

A CNC rotary table is a disc-shaped metalworking device used to obtain precise workpiece positioning. It enables a metalworker to cut or drill a workpiece at precise intervals around a vertically or horizontally fixed axis. A rotary table can be both manually or computer numerical controlled. Certain types of rotary tables are designed to be used with indexing plates or dividing plates for specialized operations. A rotary table used together with one of these positioning plates is generally referred to as a dividing or indexing head.

 

The CNC rotary table device typically has a solid base that can be attached to a separate fixture or table using clamps. This device is basically a rotating disc which holds the workpiece in place during cutting or drilling operations. The disc portion of a rotary table can be freely rotated for indexing procedures or turned by an attached control arm known as a worm wheel. Tables used in high precision operations are typically turned by a duplex-type worm wheel to compensate for backlash. Rotary tables used in automated metal working processes are turned by computer numerical controlled machinery.

 

CNC rotary tables are most often used in a flat position with the table’s axis having a vertical orientation. They are sometimes mounted with the axis oriented in a horizontal fashion so that a tailstock can be used to support the free end of the workpiece. When this device is attached to a secondary table, the workpiece can be centered on the rotary table’s axis which is then centered on the cutting tool’s axis. In this configuration, the axes of the rotary table, secondary table, and cutting tool are coaxial to facilitate concentric cutting operations. This configuration also permits the secondary table to be offset for drilling equidistant holes in a workpiece.

 

It is also a necessary component for many different types of machining and milling procedures. This versatile device can be utilized to perform specialized tasks such as machining spanner flats on bolts and drilling holes in flanges. In certain other configurations, a rotary table can also be used cut complex curves, arcs, and round pieces with protruding tangs. Rotary tables are sometimes used to produce a large-diameter hole in a workpiece by cutting in a tight circular path. This device can also use in place of a lathe when it is operated by a stepper motor combined with a computer numerical controlled milling machine and tailstock.
