The base material of 3PE (three-layer polyethylene) anti-corrosion steel pipe includes seamless steel pipe, spiral steel pipe and straight seam steel pipe. Due to its excellent corrosion resistance, water vapor permeability, and mechanical properties, three-layer polyethylene (3PE) anticorrosive coatings have been widely used in the oil pipeline industry. The anticorrosive layer of 3PE steel pipe is very important for the service life of the buried pipe. Because steel pipes are coated with different external anticorrosive coatings, they are made of the same material, so some steel pipes can be buried for decades without corrosion, but others can leak after a few years.

3PE coating structure:

Layer 1: Fused epoxy resin (FBE)

The second layer is: adhesive

Layer 3: Polyethylene (PE)

In actual operation, these three materials are mixed and integrated together and processed to make it firmly combined with the steel pipe, forming an excellent anti-corrosion layer. Processing methods are usually divided into two types: winding type and circular die coating type.

3PE coating is a new type of anticorrosive coating, which combines FBE widely used in North America with 2PE anticorrosive coating in Europe. It has been accepted by the market and widely used for more than a decade.

3PE anticorrosive coatings combine the high impermeability and mechanical properties of epoxy and polyethylene materials. It is recognized as the best performing, best-performing pipeline anticorrosive paint and has been used in many projects.

3PE anticorrosive steel pipe application:

Many people only know where and how to use 3PE-coated anticorrosive steel pipes. It is a kind of widely used anticorrosive steel pipe, that can be used in coal mine drainage, underground spraying, positive and negative pressure ventilation, gas extraction, fire sprinkler pipe network, thermal power plant process wastewater waste residue reuse. Water pipeline. It also has excellent maintainability in feed lines for fire and sprinkler systems. It is also suitable for high-rise building water supply, heating pipe network heating, water supply engineering, natural gas transmission, buried water pipelines, oil pipelines to transport corrosive media process pipelines, chemical and pharmaceutical, printing and dyeing industry, sewage treatment discharge pipe, sewage pipe, and biological tank anticorrosion engineering. Agricultural irrigation pipe, deep good pipe, drain pipe, etc. 3PE-coated anticorrosive steel pipe is very important in current civil infrastructure construction.
