Definition and Classification of Pipe Fittings


Definition of pipe fittings:
Pipe fittings are parts that connect pipes into pipelines. According to the connection method, it can be classified into socket pipe fittings, threaded pipe fittings, flange pipe fittings and welded pipe fittings. It is made of the same material as the pipe. There are elbows, flanges, three-way pipes, four-way pipes (crossheads) and reducer pipes (large and small heads), etc. Elbow is used for the place where the pipe bends; Flange is a part used to connect the pipe ends to each other. Three-way pipe is used at the place where the three pipes converge. The four-way pipe is used for the place where four pipes converge; Reducing pipes are used where two pipes of different diameters are connected.
 

Classification of pipe fittings:
Classified by application:
1. The pipe fittings used for connecting pipes are: flange, union, pipe clip, clamping sleeve, clamp, etc.
2. Pipe fittings for changing pipe direction: elbows.
3. Pipe fittings for changing pipe diameter: reducing diameter.
4. Add pipe fittings for pipeline branches: tee and cross.
5. Pipe fittings for pipeline sealing: gaskets and sealing tape.
6. Pipe fittings for pipeline fixing: snap ring, towing hook, lifting ring, bracket, etc.
