3PE anti-corrosion steel pipe connection method

1. Welding connection

This connection method is relatively traditional, its structure is simple, and any form of components can be directly connected. It is not only economical to use materials, but also does not weaken the cross-section, is easy to manufacture and process, and can even realize automatic operation. In addition, the welded connection has good airtightness and high structural rigidity. However, from the perspective of emergency repair efficiency, it may not fully meet the needs of today's environment.

2.Flange connection

In this connection method, the flange is welded to the pipe mouth, the connection between the two pipe mouths is achieved by welding or wire flange, and then the two welded flanges are used for butt joint, Spacers need to be added to the center part. This connection method has high applicability in some specific situations.

3.Trench connection

This is currently the main technology for connecting liquid and gas pipelines. The pipe fittings it requires include rigid joints, flexible joints, mechanical tees and grooved flanges, as well as elbows, tees, crosses, reducers, blind plates, etc. This connection method is widely used because of its efficiency and convenience.

Each connection method has its unique advantages and applicable scenarios. Which connection method to choose mainly depends on the specific usage environment and needs. In practical applications, it is necessary to comprehensively consider the specific situation and select the most appropriate connection method.
