As we all know, steel products are prone to severe corrosion under harsh environmental conditions, thereby shortening the service life and service life of steel pipes and increasing costs, while the service life of thermal insulation and anti-corrosion steel pipes is relatively long. Typically, it has a service life of 30 to 50 years, which actually reduces the cost of use.
3PE anti-corrosion and insulated steel pipes have good thermal insulation properties, and their heat loss is only 25% of traditional steel pipes. Although short-term operation has no obvious effect, long-term operation can save a lot of resources, significantly reduce operating costs, and has relatively strong waterproof and corrosion resistance.
3PE steel pipe has excellent corrosion resistance and can maintain stable performance in complex oil and gas transportation environments, so it is widely used in oil and natural gas transportation. In long-distance transportation, 3PE coated anti-corrosion steel pipes can effectively reduce leakage and maintenance costs and improve transportation efficiency.

3PE anti-corrosion coating steel pipes
3PE anti-corrosion generally consists of 3 layers of structure:
The first layer of epoxy powder (FBE>100um)
The second layer of adhesive (AD) 170~250um
The third layer of polyethylene (PE) 1.8~3.7mm
The preservatives for the inner wall of steel pipes include: one type of thermal melting glass powder preservative (high temperature melting), one type of liquid environmental protection agent, and a common liquid environment IPN8710 (room temperature cold heating). Various types of internal wall preservatives have different performance characteristics:
