What is 3PE coating

• 3PE anti-corrosion steel pipe is a very common anti-corrosion material, and its anti-corrosion performance is very superior. There are three main base materials for 3PE anti-corrosion steel pipes, namely seamless steel pipes, straight seam steel pipes and spiral steel pipes. Of course, the materials used are different, and the performance of 3PE steel pipes is also different. However, no matter what kind of base material is used, The anti-corrosion performance of anti-corrosion pipes is very excellent. The excellent anti-corrosion performance of 3PE is inseparable from its own anti-corrosion layer. Generally, pipes made of the same material may rot after being buried underground for a few years, while anti-corrosion steel pipes can be guaranteed not to rot for decades. The key is the anti-corrosion layer.

• Anti-corrosion structure

3PE anti-corrosion generally consists of a three-layer structure, namely epoxy powder, adhesive and polyethylene.
In actual operation, these three materials are mixed and melted into one. After processing, these materials are firmly combined with the steel pipe to form a very excellent anti-corrosion coating, which is the fitting of the anti-corrosion steel pipe.
3PE anti-corrosion steel pipe coating is also a three-layer polyethylene anti-corrosion coating. It is a new type of anti-corrosion steel pipe coating that is cleverly combined with 2PE anti-corrosion coating and epoxy powder anti-corrosion steel pipe coating widely used in North America. It has been recognized and used in the world for more than ten years.
The coating of 3PE anti-corrosion steel pipe is epoxy powder anti-corrosion coating. Contact between the bottom layer and the surface of the steel pipe, the middle layer is a copolymer adhesive with branched structural functional groups. The surface layer is high-density polyethylene anti-corrosion coating.

3PE anti-corrosion coating combines the high impermeability and high mechanical properties of epoxy resin and polyethylene materials. So far, it is recognized as the best pipeline anti-corrosion coating in the world in terms of application effect and performance. 3PE anti-corrosion steel pipes are widely used in various projects because of their superior performance.
Polyethylene anti-corrosion steel pipe and anti-corrosion technology
There are two types of anti-corrosion for the inner wall of steel pipes: one is hot-melt epoxy resin powder anti-corrosion (sintered at high temperature), and the other is liquid epoxy coating, which is sprayed at room temperature and low temperature.
