Pipe Fittings

Pipe fitting is a component that connects segments in a series, offset, multiport, or installation configuration. Pipe fittings come in a variety of shapes and sizes and are composed of a variety of materials. Pipe joints, elbows, tees, sleeves, flanges, diaphragm pipe fittings, reducers, valves, and so on are all examples of pipe fittings. Pipe fittings are a type of pipe system. Steel pipes, pipe fittings, flanges, bolts and nuts, washers, valves, and pressure bearing elements of other piping components comprise the entire piping system.

What is Pipe Fitting?


Pipe Fittings are pipeline components that aid in the routing of pipes for directional changes, size modifications, and branch connections. Pipe fittings such as piping elbows, piping reducers, tee connections, olet connections, caps, crosses, and so on are widely used in the piping and plumbing industries. Depending on the layout or process requirements, different pipe fittings fulfill different tasks. Pipe fittings are made individually and must be purchased separately. End connectors are used to connect pipe fittings to pipework. Pipe fittings are critical to the effective operation of pipes and tubes in a variety of applications. This article will provide an overview of the many types of pipe fittings used in the piping, pipeline, and plumbing industries.

Types of pipe fittings & applications of pipe fittings

Pipe Elbow

To alter the angle or direction of a pipe run. 90-degree and 45-degree rotations are the most prevalent. The fitting’s sweep specifies how quickly a transition or change in direction occurs.

Pipe Tee

Allows for branch lines since it is shaped like the letter T.


Used to connect two straight lengths of the same diameter pipe.


Used to connect pipes of varying sizes. Changes in diameter gradually.


Control devices for the movement of liquid or gas through or from a pipe. (For example, compression valves, ball valves, sleeve-cartridge valves, ceramic disc valves, and so on.)

Connection Types of Pipe Fitting

Butt Weld Fittings

This is a type of weld that is used to bind two or more pieces together. Alternatively, it refers to the process of welding two or more parts together, which includes the weld, the fusion zone, and the heat impacted zone. A high-temperature heat source is used to generate the welded connection in fusion welding. The weld metal, the fusion zone, the heat impacted zone, and the base metal make up the welded connection. The temperature and heat concentration of the heat source used in various welding methods vary. As a result, the size of the heat-affected zone and the microstructure of the welded connection, as well as the quality of the joint, vary. Furthermore, the mechanical protective benefits of various welding methods vary. As a result, weld metal purity, or the concentration of harmful contaminants in the weld, will vary, as will weld performance.

Socket Weld Fittings

Socket welded pipe fittings extend the pipe into the valve body for welding. After forming, the shape is similar to that of an internal thread connection. Carbon steel tubing with a diameter of less than 2″ is used for socket welding. Inserting the pipe into the socket of the pipe fitting, reaching the socket placement stage, and then welding an argon protective fusion ring along the contact between the socket end of the pipe fitting and the pipe’s outer wall are the specific connection methods. During the welding operation, there was no use of welding wire (replaced by the socket end edge of the pipe fitting). It’s linked to a specific sort of welding. Pipe connection method with “no joint connection.”
