Pipe fitting is a general term for the parts and components in the pipeline system that can connect, control, change direction, shunt, seal and support.
Pipe is introduced
Steel pipe fittings are pressure pipe fittings. According to different processing technology, it can be divided into four categories, namely butt welding pipe fittings (divided into two kinds of weld and non-weld), socket welding and threaded pipe fittings, flange pipe fittings.
Commonly used classification
There are many types of pipe fittings, which are classified according to purpose, connection, material and processing method.
According to utility cent
1. Pipe fittings used for connecting pipes with each other are: flange, splice, pipe hoop, clamp, sleeve, throat hoop, etc
2. Pipe fittings that change the direction of the pipe: elbow and bend
3. Pipe fittings for changing pipe diameter: reducing pipe (reducing pipe), reducing elbow, branch pipe table and reinforcing pipe
4, add pipe branch fittings: three, four
The picture
5. Pipe fittings for pipeline sealing: gasket, raw material belt, thread hemp, flange blind plate, pipe plug, blind plate, head, welding plug
6. Pipe fittings for pipe fixing: clasp, hook, lifting ring, bracket, bracket, pipe card, etc
According to the connection points
1. Welding pipe fittings
2. Threaded pipe fittings
3. Clamp casing parts
4. Clamp pipe fittings
5. Intubation fittings
6. Stick the connecting parts
7. Hot melt pipe fittings
8. Bending double fuse pipe fittings
9. Rubber ring connecting pipe fittings
According to the material points
1, cast steel pipe fittings: ASTM/ASME A234 WPB, WPC
