(1) Welding connection of 3PE anti-corrosion steel pipe
If there is no need to disassemble, then welding can be used. This is a relatively traditional connection method, with a simple structure, and components of any method can be directly connected; economical materials, no weakening of the cross section; convenient manufacturing and processing, and automatic operation can be realized; The tightness of the connection is good, and the structural rigidity is large. In terms of repair efficiency, it is not suitable for today's environment.
(2) Flange connection of 3PE anti-corrosion steel pipe
The flange is welded to the nozzle, and the connection between the two nozzles is firstly welded to the flange or wire-connected to the flange, and then the two welded flanges are used for the butt joint, and a gasket is added in the middle.
(3) Connection of grooved pipe fittings for 3PE anti-corrosion steel pipes
This connection method is 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 with elbows, tees, crosses, Reducer, blind plate, etc.
