What is a pipe fitting

Pipe fittings are a general term for the components that play a role in connecting, controlling, changing direction, diverting, sealing, supporting, etc. in pipeline systems, mainly including elbows, tees, reducers, flanges, heads, and other types.

Definition and function of pipe fittings

Pipe fitting is an important component of pipeline systems, with core functions including connecting pipes, changing flow direction (such as elbows), diverting (such as tees), adjusting pipe diameter (such as reducers), sealing interfaces (such as flanges), and supporting pipeline structures. ‌‌

Main types and uses

Connecting fittings.
Flange: Used for detachable connections, facilitating installation and maintenance. ‌‌
Threaded fittings: Sealing is achieved by tightening the threads, suitable for low-pressure systems. ‌‌
Directional and diversion fittings.
Elbows: Divided into angles of 45 °, 90 °, etc., they are used to change the direction of pipelines and can be made through welding or molding processes. ‌‌
Three way/four-way: to achieve the diversion or convergence of pipelines, such as equal diameter tees or diagonal tees. ‌‌
Variable diameter and sealing fittings.
Reducing pipe (big and small head): Connecting pipes of different diameters, commonly used in steam or drainage systems. ‌‌
Head/Blind Plate: Closed pipe end or temporary isolation pipeline, blind plate can be divided into flange cover and plug-in type. ‌‌
Special craftsmanship and innovative design

Some pipe fittings adopt high-pressure forging (such as alloy steel elbows) or patented technology (such as clamp type pipe fittings with water leakage detection function) to meet specific working conditions. ‌‌‌‌
