Water is the source of life. For the carrier of drinking water transportation, coated spiral steel pipe is the most common.

TPEP anticorrosive spiral steel pipe, which is externally wound three-layer polyethylene inner melted epoxy anticorrosive spiral steel pipe, has the advantages of high strength, good integrity, good plasticity, can withstand high external pressure and internal pressure, and has good adaptability to foundation. Compared with the manifold and ductile iron pipe, it is lighter in weight, easy to install, less joints and no leakage. The inner wall hot-melt epoxy resin coating has good adhesion, long durability, strong corrosion resistance and a service life of more than 50 years. 

The coating of TPEP anticorrosive spiral steel pipe adopts high pressure extrusion winding technology. The coating is tough, wear resistant, impact resistant and bending resistant. It can effectively prevent the mechanical damage in construction and the damage of plant roots and soil environmental stress in use .

TPEP anticorrosive steel pipe, the inner wall of the product adopts thermal spraying epoxy powder anticorrosive method, the powder is uniformly coated on the surface of the pipe after high temperature heating and melting. The product is suitable for pipeline transportation under various conditions. The outer wall adopts 3PE anti-corrosion technology, which is a 3-layer structure of polyethylene outer wall anti-corrosion, widely used, and has good anti-corrosion protection for steel pipes and long service life.

The externally wound polyethylene inner melted epoxy anticorrosive steel pipe (TPEP pipe) is the fourth generation of pipeline anticorrosive form. It is a special anticorrosive technology. The anticorrosive material used for pipeline anticorrosion is customized according to the production process and is specifically used for pipeline Epoxy powder is a thermosetting powder coating, which has the characteristics of corrosion resistance and toughness. The particular epoxy powder is uniformly coated on the surface of the pipe body by heating the steel pipe matrix, and the epoxy powder adhering to the surface of The preheated steel pipe has a high pressure by bonding with a surface coating of a steel pipe, and has a good chemical resistance and a cathodic peeling resistance.
