1. The parent material and structure of 3PE anti-corrosion steel pipe
The parent material of 3PE anti-corrosion steel pipe 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 oil pipeline industry for its good corrosion resistance, water vapor permeability resistance and mechanical properties.
2. The importance of 3PE anti-corrosion layer to pipeline life
The anti-corrosion layer of 3PE anti-corrosion steel pipe is crucial to the life of buried pipelines. Some pipelines of the same material are buried underground for decades without corrosion, while others leak in a few years. This is because they use different external anti-corrosion layers.
3. Definition and common methods of 3PE anti-corrosion steel pipe
3PE anti-corrosion steel pipe refers to a 3-layer polyethylene coating (MAPEC) external anti-corrosion steel pipe, which is a commonly used anti-corrosion pipeline in China. Other anti-corrosion methods include IPN8710, FBE epoxy powder, epoxy coal tar and other anti-corrosion methods. Generally refers to the anti-corrosion of the outer wall of the steel pipe.
4. Diversified applications of 3PE anti-corrosion steel pipes
Many people only know one of the uses of 3PE anti-corrosion steel pipes, but its functions really cover a wide range. It is suitable for underground water supply and drainage in coal mines, underground grouting, positive and negative pressure ventilation, gas extraction, fire sprinkler and other pipe networks. Process water waste residue and return water transportation pipelines in thermal power plants. It has great applicability for water supply pipelines of anti-sprinkling and sprinkler systems. Cable protection casings for power, communications, highways, etc.
5. Application prospects of 3PE anti-corrosion steel pipes in various industries
Applicable to pipelines for high-rise building water supply, heating network heating, tap water projects, gas transportation, buried water transportation, etc. Process pipelines for transporting corrosive media in oil pipelines, chemical pharmaceuticals, printing and dyeing and other industries. Sewage treatment discharge pipes, sewage pipes and biological pool anti-corrosion projects. Agricultural irrigation pipes, deep well pipes, drainage pipes and other networks, etc. It can be said that 3PE anti-corrosion steel pipes are indispensable in the current construction, and I believe that through the extension of technology, it will still have more brilliant achievements in the future.
