PVC plumbing fitting and some of its types

Introduction to PVC plumbing fitting

Pipe fittings or the PVC plumbing fitting are the piping component which helps in changing the direction of the flow. The components include PVC elbows, PVC tees, etc.

Reducing the size of the pipe, there are reducers which are called as reducing tees. For connecting the different components pipe couplings are used. All together when it is intended to stop the flow, caps are used.

Types of PVC plumbing fitting

There are many types of pipe fitting used in piping. The main components are an elbow, tee, reducer, Union, pipe coupling, cross, cap, Swage nipple, plug, Bush, expansion joint, adaptors, let that includes weldolet, socket, elbowlet, Thredolet, Nipolet, Letrolet, Swepolet), Steam Traps, Long Radius Bend, Flanges and Valve.

These are the standard fittings which are either forging or wrought. It is already known that only seamless pipes are used to produce wrought fittings. The welded fittings which are of large diameter and manufacture directly from the plate.

Fittings with a different type of end connections.

Pipe elbow

Elbow is most widely used than any other pipe fittings. It gives considerable flexibility to change the direction of the pipe. The elbow is mainly available into standard types that include 90 degrees and 45 degrees. It can also be cut them some other degrees. They are available into radius types such as short radius and long radius.

90-degree elbow pipe is installed between the pipes to change the direction of the pipe by 90 degrees. You can find them in both long and short radius form.

The 45-degree elbow can be installed between the pipes to change the direction of the pipe by 45 degrees.

Long radius elbows are used in the pipes when the pressure loss is less compared to the short radius elbow.

Short radius elbow is used under Limited space applications. But it has a high-end pressure drop due to a sudden change in the direction of the flow.

Reducing elbow

Under the PVC plumbing fitting, the 90-degree reducing elbow is specifically designed to change the direction as well as to reduce the size of the pipe piping system. It will eliminate the one pipe fitting and also reduce the welding by more than one third. This will lower the resistance to flow and reduce the effect of stream turbulence and potential internal erosion. It is for these outcomes, gradual reduction in diameter is employed throughout the arc.

Pipe bend

When pigging is required in fluid transportation, long radius pipeline is used. Pipe bend can help with long radius and smooth change of direction as it has very less pressure drop. It makes board smooth flow of the fluid and pig possible. Three dimensional and five-dimensional pipe bends are very commonly available.

Miter bend

These are not standard pipe fittings but they are fabricated from pipes. Preference for this is size 10 inch. Large size elbows are also available. However, you cannot use the miter bend to restrict the low-pressure Water Line. They are generally fabricated in 2, 3 and 5 pieces.
