(1) Welding connection:
If there is no need to disassemble, you can choose welding. This is a more traditional connection method. It has a simple structure and can directly connect components of any form. It is economical to use materials and does not weaken the cross-section. It is easy to manufacture and process and can realize automated operations. The connection has good airtightness and high structural rigidity. Emergency repair efficiency is not suitable for today’s environment.
(2) Flange connection:
Weld the flange to the pipe mouth. To connect the two pipe mouths, first weld the flange or wire the flange, and then use the two welded flanges to butt together, with a gasket in the middle.
(3) Groove pipe fitting connection:
This connection method is currently the main technology for connecting liquid and gas pipelines. The pipe fittings required for this connection method include rigid joints, flexible joints, mechanical tees, and grooved flanges including elbows, tees, crosses, Reducers, blind plates, etc.
