What are the common connection methods of
3PE anti-corrosion steel pipes?
(1) Welding connection: If there is no need to disassemble, then welding can be used. This is a more traditional connection method, with a simple structure, and components of any form can be directly connected; economical materials, without weakening the section; manufacturing, and processing It is convenient and can realize automatic operation; the airtightness 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: Weld the flange to the nozzle. 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. The center should be spaced.
(3) Connection of grooved pipe fittings: This connection method is the main technology for connecting liquid and gas pipelines. The pipe fittings required by this connection method include rigid joints, flexible joints, mechanical tees, and grooved flanges with bends Head, tee, cross, reducer, blind plate, etc.
