As a terminal technology product in the steel pipe industry chain, anti-corrosion steel pipes have always occupied a very important position in the industry. In recent years, with the development and application of new anti-corrosion technologies for steel pipes, anti-corrosion steel pipes have become more and more widely used in engineering, and many factories specializing in anti-corrosion steel pipe processing have sprung up. 3PE anti-corrosion steel pipe is an important variety of anti-corrosion steel pipes. 3PE anti-corrosion steel pipe is a three-layer polyolefin coating (MAPEC) anti-corrosion steel pipe commonly used in my country. The main base materials of steel pipes include seamless steel pipes, spiral structural steel pipes, straight seam welded pipes, etc.

The first layer of epoxy powder (FBE > 100 μm)
Use adhesive (AD) 170 ~ 250 um for the second layer
The third layer of polyethylene is 2.5 ~ 3.7mm

In practice, these three materials are mixed, processed, and mixed firmly with the steel pipe to form an excellent anti-corrosion coating. The processing technology methods can generally be divided into two types: winding type and round die coating type. The bottom layer of the 3PE anti-corrosion steel pipe coating is in contact with the surface of the steel pipe coated with epoxy powder anti-corrosion coating. The middle layer is a copolymer adhesive with a branched structure and function, and the surface layer is a high-density polyethylene anti-corrosion coating.

3PE anti-corrosion steel pipe coating (three-layer polyethylene anti-corrosion coating) is a new type of anti-corrosion steel pipe coating that combines Europe's 2PE anti-corrosion coating and epoxy powder anti-corrosion pipe coating (FBE), which was first introduced in North America in the early days Widely used, it has been used for decades now. 3PE anti-corrosion technology and coatings can combine the high impermeability and high mechanical system performance of epoxy resin and polyethylene, and so far it has been widely used in many projects.

As for the use of 3PE anti-corrosion steel pipes, its coverage is very wide. It is suitable for pipe networks such as underground water supply and drainage, underground shotcrete, positive and negative pressure ventilation, gas emissions, fire sprinklers, etc.; it is suitable for pipelines in the transportation system for waste residue and process water return in thermal power plants; it also has good performance for the water supply pipelines of automatic sprinkler fire extinguishing systems. Applicability; it can also be used as a working casing for cable protection in power supply, communications, roads, etc.

The long-term use of 3PE anti-corrosion and insulated steel pipes can reduce production costs and have relatively strong waterproof and anti-corrosion capabilities. It can be directly buried underground or in water without the need for attached pipe trenches. Construction is simple and fast, and comprehensive management cost control is relatively low.
