What disadvantages does e-PSP steel-plastic composite pressure pipe solve for traditional pipelines?

Disadvantages of 1 and ppr: large expansion coefficient, weak compression resistance and good environmental protection;

2, galvanized steel pipe: easy to rust, corrosion, poor environmental protection performance, affecting water quality;

3, stainless steel: high cost, usually using 304 thin-walled stainless steel pipe, welding (connection) there are security risks;

4. Plastic-lined steel pipe: It is easy to run water at the joint, which makes the inner wall of the pipe rust and corrode, and has poor environmental protection performance, which affects the water quality and greatly shortens the service life.

5.e-PSP steel-plastic composite pressure pipe: combines the advantages of plastic pipe and metal pipe, and eliminates the disadvantages; The inner and outer plastic lining (ppr) enhances the anti-corrosion ability, prolongs the service life, and has stable long-term energy consumption. The middle steel pipe increases the bearing capacity of the system, and the water leakage rate of the intelligent connection mode (electromagnetic welding) system is zero.
