3PE
anti-corrosion steel pipe base material includes seamless steel pipe, spiral steel pipe and straight seam steel pipe. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the petroleum pipeline industry for its good corrosion resistance, water vapor permeability and mechanical properties. 3PE anti-corrosion steel pipe An anti-corrosion layer is very important for the life of buried pipelines. Some pipes of the same material are buried in the ground for decades without corrosion, and leaks occur in some years. It is because they use different outer coatings.
Steel pipe outer wall anti-corrosion form
3PE anti-corrosion generally consists of three layers of structure:
A layer of epoxy powder (FBE>100um)
Two-layer adhesive (AD) 170～250um
Three layers of polyethylene (PE) 1.8 ~ 3.7mm
In the actual operation, the three materials are mixed and integrated, and processed to make it firmly combined with the steel pipe to form an excellent anti-corrosion layer. The processing method is generally divided into two types: a winding type and a round mold coating type.
3PE anti-corrosion steel pipe coating is also (three-layer polyethylene anti-corrosion coating), which is a new anti-corrosion produced by the combination of European 2PE anti-corrosion layer and North American widely used epoxy powder anti-corrosion steel pipe coating (FBE). Steel tube coating. It has been recognized and used in the world for more than ten years.
The coating of the 3PE anti-corrosion steel pipe is an epoxy powder anticorrosive coating which is in contact with the surface of the steel pipe, and the intermediate layer is a copolymerized binder with a branch structure functional group. The top layer is a high density polyethylene anticorrosive coating.
3pe anti-corrosion coating combines the high impermeability and high mechanical properties of epoxy resin and polyethylene. It has been recognized worldwide as a pipeline anti-corrosion coating with good effect and good performance, and has been applied in many projects.
