1) Elbow Pipe Fittings
Elbows are generally utilized to make a shift in the direction of the flow between two pipes. Elbow pipe fittings are mainly available with an angle of 22.5°, 45° or 90°. If the pipes are of the exact same diameter, then normal elbows are preferred, or else reducer elbows are utilized. Elbows are prepared using different types of substances. These usually come up with female threads and can be fixed easily by socket or butt welding as well.
2) Tee type Pipe Fittings
Tee type pipe fitting is a part of the plumbing system, which is basically in the form of a T-shape. It comprises one inlet and two outlets, and the outlets are organized at 90° to the central line connection, i.e. inlet. This type of pipe fitting can also be used for combining the flow from two inlets to a single outlet. If the three sides of T-fitting are of the same sizes, then it is known as "Equal Tee", and if it's not the same, it is called "Unequal Tee". Moreover, these are readily available in different sizes as well as different materials.
3) Reducer Pipe Fittings
Reducer is a pipe fitting element that helps in reducing the flow size from larger to smaller by curtailing the size of the pipe. Also, there are two types of reducer pipe fittings available in the market. The first one is called a concentric reducer, which is cone-shaped and gradually diminishes around the pipe, but in this particular case, there's a high chance of air being accumulated which may result in cavitation. The second is known as eccentric reducer, which has one edge parallel to the connecting pipe and due to which accumulation of air is just impossible.
4) Coupling Pipe Fittings
Coupling pipe fittings are mainly utilized to connect the pipes that share the same diameter. Coupling is also beneficial when there is a problem of leakage or if the pipe is broken. Typically, there are two types of coupling pipe fittings available - Compression coupling and Slip coupling.
Compression coupling is a normal coupling which is fused between two pipes, and it is highly useful in preventing leakage because the arrangement of gaskets or rubber seals is done on both sides, or else glue is provided, one can use that.
Slip coupling is simpler to put in, and it includes two pipes which are organized as one into another, where the inner pipe can be elevated up to some extent. So, a long length damaged pipe can be fixed by using slip coupling.
