There are three common connection methods for 3PE anti-corrosion steel pipes

The connection of 3PE anti-corrosion steel pipes is also common in daily projects. For the connection of anti-corrosion steel pipes, the following are three common connection methods. I believe that after understanding these three common connection methods, you will have a different understanding of the connection of 3PE anti-corrosion steel pipes.

(1) Welding connection. If there is basically no need to disassemble, then welding can be used. Compared with the traditional connection method, the structure is simple, and the components of any method can be directly connected; the material is economical, and the section is not weakened; manufacturing and processing It is convenient and can complete automatic operation; the tightness of the connection is good, and the structural rigidity is large. In terms of emergency repair power, it is not suitable for today's environment.

(2) Flange connection. When the flange is welded to the nozzle, the connection between the two nozzles is to weld the flange or wire the flange respectively, and then use the two welded flanges for the butt joint. Add a spacer to the center.

(3) Connection of grooved pipe fittings. This connection method is the main push technology for the connection of liquid and gas pipelines. The pipe fittings required by this connection method are rigid joints, flexible joints, mechanical tee, and grooved flanges. head, tee, cross, reducer, blind plate, etc.
