The various types of pipe fittings are divided into three categories: Female branch tee, threaded connection, and bushings. Read on to know the details about these fittings. There are also different types of swages available. You can choose one of the three types as per your requirements. Below you will find a detailed explanation of each type.
Threaded Connection
A threaded connection is a pipe fittings feature that is used to connect two pieces of pipe, such as ASTM A335 P5 pipes, together. The threaded part of a pipe is stronger in compression than it is in stretching. Therefore, the female part of a pipe will stretch to failure before the male part does. The resistance of the materials to stretching determines how tight a joint is. Steel is seven times stronger than PVC, but plastic joints will tend to be looser when tightened than their metal counterparts.
The study simulated a pipe-to-pipe threaded connection by coupling two segments of pipe with a threaded pipe connector. The test specimen was fixed to a steel fixture with a PZT patch mounted on the surface of the coupling part. Its geometries and material parameters are given in Table 1.
A female threaded pipe fitting has a tapered flank and a tapered male thread. The taper in the threads causes flanks to compress against one another. A leak-free connection is important, so a sealant compound is often used, and a tapered thread is easy to disassemble. This leak-tight connection is the primary reason why most process instrumentation uses a tapered thread connection.
Bushings
In the mechanical world, bushings for pipe fittings connect two or more pipes of a different diameter. The bushings are threaded on both the inside and outside and are usually made of a variety of materials. A supplier of pneumatic components, Universal Power Conversions, offers various varieties for a variety of applications. These sleeve-shaped pipe fittings are made of various materials, including copper and brass.
PVC pipe fittings and couplings are common examples of these bushings. They allow two pipe diameters to connect without the use of casing. PVC reducer bushings have large and small sockets and fit on both ends of the pipe, thereby transitioning from one pipe diameter to another. The resulting transition between the two sizes of pipe fittings is seamless, and no adhesive is required. However, they are not suitable for every application.
Schedule 40 PVC bushings are another option for pipe fittings. They provide long-term durability as well as a variety of other benefits. They can withstand low internal pressure and are not affected by corrosion. While Schedule 40 PVC bushings are not ideal for hot water applications, they are preferred for landscaping and aquaculture settings. PVC bushings also do not corrode from exposure to water and soil contaminants.
Adapter Fittings
Adapter fittings for pipes serve two primary functions: they terminate and extend pipe runs and connect dissimilar pipe types. These tools are also known as pipe couplings. They feature a female or male IPS thread on one end, while the opposite gender is on the other. They are used to connect various pipe types to plumbing fixtures. Size is the most important parameter to consider when choosing pipe adapters. There are two types of adapter fittings: straight and non-straight.
Stainless steel adapter fittings can withstand 420 bar of pressure during normal system operation. However, this pressure will drop to 331 bar at 4000C, with a de-rating factor of 0.79. Copper and brass adapter fittings do not exceed 331 bar of pressure in any temperature range. The temperature rating for each type of adapter fitting depends on the pipe material and its diameter. In most cases, you will need a minimum of 2 and a half turns past hand tight.
Adapters provide a number of benefits. Firstly, they provide a leak-free connection. Adapter fittings are also ideal for high-pressure and high-vibration applications, and they have reduced the chances of leaks. Adapters also offer a seamless transition from piping systems to tubing systems. Unlike threaded and welded connections, adapters have a simple, standard material construction, eliminating the risk of galling on the assembly line.
Female Branch Tee
The female branch tee is one of the most common types of pipe fittings. It connects a fractional tube or a female NPT thread. The branch tee comes in metric and inch sizes and is a versatile tool that is widely used in a variety of industries. Read on to learn more about the different types of female branch tee pipe fittings.
There are a variety of different types of pipe fittings, such as Male and Female Branch Tee. Female Branch Tee pipe fittings are usually made of steel and are suitable for construction, trucking, and factory automation. These fittings are made to be durable and simple to install, so they’re easy to use. This type of fitting has the advantage of being inexpensive and versatile, which makes it an excellent choice for many applications.
The tee fitting is a T-shaped piece of pipe that is used to connect two pipes at a 90-degree angle. They come in a variety of sizes and are made of various materials. One type is a straight tee, while the other has two branches that angle at 45 degrees. Some are used in the food and beverage industry, while others are found in the manufacturing and processing industries.
Flange
There are several standards that apply to flanges for pipe fittings. These standards are called the JIS and are designed for industrial activities in Japan. They were coordinated by the Japanese Industrial Standards Committee. Formerly attached to the METI (Meiji Telecommunications Institute), the Japan Standards Association is now an independent foundation with a broad range of programs. The JIS-B division consists of a variety of flanges of different sizes.
A flange 22 includes a cylindrical collar 44 extending from the butt end of the conduit. The collar is tapered outward so that the collar portion is in contact with the bottom surface of the conduit. A flange rim 48 has a bore 50 that is slightly larger than the recess 36 and is less than the outside surface of the conduit 16. An annular bottom 52 is defined by the terminus of the bore.
Flanges for pipe fittings are also available with lining. However, they are not of the same quality as a flange. The flange material is determined during the selection process. Usually, the flange material is the same as the pipe. Flanges are also governed by ASME standards. Specifically, ASME B16.5 describes the dimensions, dimensional tolerances, and material qualities of flanges.
Diverter Tee
A diverter tee is a special pipe fitting that enables water to flow in either direction from the main pipe. Its sizing chart indicates that it is designed to handle up to one gpm of water. If the main is only rated for one and a quarter gpm, the diverter tee should be sized to pass one gpm of water into the radiator.
It has a high-pressure drop, so you must ensure the piping system’s head pressure is sufficiently high to move the water through it. The higher the head pressure, the more diverter tees are required. A split loop, on the other hand, reduces pressure drop by preventing the flow through the highest-pressure circuit. The split loop also tends to be less expensive than one-pipe systems.
When you design a diverter tee system, you should keep in mind that its hydraulics are more complicated than simple series circuits. Because it has multiple branches, the subassembly can have varying temperatures, and the flow rate through the system must be taken into consideration. Fortunately, the diverter tee’s hydraulics can be modeled using a simplified, spreadsheet or custom software. This type of simulation can help engineers refine the performance of a classic hydronic distribution system.
Dielectric Union
Using a dielectric union pipe fitting can be a great idea if you are looking for a fast, convenient method for joining pipes. Instead of welding or rotating a coupling, this method allows you to attach two pipes without a lot of trouble. When used correctly, dielectric unions will prevent corrosion and prevent leaks. In fact, these types of pipe fittings are ideal for water heaters as they help to extend their lifespan.
A dielectric union is a two-part pipe fitting that is used to prevent galvanic corrosion. This type of pipe fitting is made of two different metals, namely steel, and copper. The dielectric union will prevent corrosion by creating an electrical barrier between the two pipes. These types of pipe fittings are typically used in new construction and in adding fixtures to an existing plumbing system. Because the materials used to make them differ, plumbers need to plan ahead for placement in order to get the most out of them.
Copper and brass are commonly used in pipe fittings. Copper and brass are sensitive to acidic water, which can lead to galvanic corrosion. Dielectric unions prevent this by acting as insulators between the two metals. They also prevent corrosion by preventing the passage of current. If the two metals are connected without a dielectric union, this method could lead to electrolysis. By preventing galvanic corrosion, dielectric unions are a better option for water systems.
