3-layer PE reinforced anti-corrosion steel pipe manufacturer 3pe anti-corrosion seamless steel pipe polyethylene anti-corrosion steel pipe price

Description :

　　3PE anti-corrosion steel pipe refers to a three-layer polyolefin coating (MAPEC) external anti-corrosion steel pipe, which is a commonly used type of anti-corrosion pipeline in China. Other anti-corrosion methods include IPN8710, FBE epoxy powder, and epoxy coal tar. Generally refers to the anti-corrosion of the outer wall of steel pipes.

　　3PE anti-corrosion steel pipes have been widely used in the petroleum pipeline industry due to their excellent corrosion resistance, water and gas permeability resistance, and mechanical properties. The anti-corrosion coating of 3PE anti-corrosion steel pipes is crucial for the service life of buried pipelines. For pipelines of the same material, some may not corrode after being buried underground for decades, while others may leak within a few years. It's because they use different external anti-corrosion coatings.

　　The coating of 3PE anti-corrosion steel pipe is an epoxy powder anti-corrosion coating in contact with the bottom layer and the steel pipe surface, and a copolymer adhesive with branched functional groups in the middle layer. The surface layer is a high-density polyethylene anti-corrosion coating.

　　3PE anti-corrosion steel pipes generally consist of a 3-layer structure:

　　Layered epoxy powder (FBE>100um);

　　Second layer adhesive (AD) 170250um;

　　The third layer of polyethylene (PE) is 2.53.7mm.

　　Performance characteristics of 3PE anti-corrosion steel pipe:

　　1. Good insulation performance, with heat loss only 25% of traditional pipes, long-term operation can save a lot of energy and significantly reduce energy costs.

　　2. It has strong waterproof and corrosion-resistant capabilities, does not require a pipe trench, can be directly buried underground or in water, is easy and fast to construct, and has a low overall cost.

　　3. It also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in frozen soil underground.

　　4. The service life can reach 30-50 years, and correct installation and use can greatly reduce the cost of pipeline maintenance.
