Description :
The base materials for 3pe anti-corrosion steel pipes include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the petroleum pipeline industry due to its excellent corrosion resistance, water vapor permeability, and mechanical properties. The anti-corrosion coating of 3PE anti-corrosion steel pipes is crucial for the service life of buried pipelines. For pipelines of the same material, some may not corrode after being buried underground for decades, while others may experience leakage within a few years. It's because they use different external anti-corrosion coatings.
The Chinese name is 3PE anti-corrosion steel pipe, and the foreign name is 3PE anti-corrosion steel pipe. The types of seamless steel pipe, spiral steel pipe, and straight seam steel pipe have the meanings of 3-layer structure polyethylene wrapped external anti-corrosion steel pipe.
Many people only know one thing about the use of 3PE anti-corrosion steel pipes, but they don't know the other. Its function is really broad, and it is suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, fire sprinkler and other pipe networks in coal mines. Thermal power plant process water waste residue and return water transportation pipeline. The water supply pipelines for anti spray and sprinkler systems have greater applicability. Cable protection sleeves for power, communication, highways, etc. Suitable for high-rise building water supply, heating network, water supply engineering, gas transmission, buried water transmission and other pipelines. Process pipelines for transporting corrosive media in industries such as petroleum transportation pipelines, chemical pharmaceuticals, and printing and dyeing. Anti corrosion engineering for sewage treatment discharge pipes, sewage pipes, and biological tanks. For agricultural irrigation pipes, deep well pipes, drainage pipes and other network applications, it can be said that 3PE anti-corrosion steel pipes are essential in current construction, and we believe that with the extension of technology, they will have even more brilliant achievements in the future.
Introduction to 3PE anti-corrosion steel pipe:
3PE anti-corrosion steel pipe refers to a three-layer structure polyethylene coating (MAPEC) external anti-corrosion steel pipe, which is a commonly used type of anti-corrosion pipeline in China. Other anti-corrosion methods include IPN8710, FBE epoxy powder, epoxy resin, etc. Generally refers to the anti-corrosion of the outer wall of steel pipes.
3PE anti-corrosion steel pipe anti-corrosion structure:
Anti corrosion form of steel pipe outer wall;
3PE anti-corrosion generally consists of three layers of structure:
One layer of epoxy powder (FBE>100um).
Di two-layer adhesive (AD) 170-250um.
The third layer of polyethylene (PE) is 1.8-3.7mm.
In practical operation, the three materials are mixed and integrated into one, and processed to firmly bond with the steel pipe to form an excellent anti-corrosion layer. Its processing methods are generally divided into two types: winding and circular mold wrapping.
The 3PE anti-corrosion steel pipe coating, also known as the three-layer polyethylene anti-corrosion coating, is a new type of anti-corrosion steel pipe coating that cleverly combines the European 2PE anti-corrosion coating with the widely used epoxy powder anti-corrosion steel pipe coating (FBE) in North America. It has been recognized and used worldwide for over ten years. The coating of 3PE anti-corrosion steel pipe is an epoxy powder anti-corrosion coating in contact with the bottom layer and the steel pipe surface, and a copolymer adhesive with branched functional groups in the middle layer. The surface layer is a high-density polyethylene anti-corrosion coating. The 3PE anti-corrosion coating combines the high permeability and mechanical properties of epoxy resin and polyethylene materials. So far, it is globally recognized as an effective and high-performance pipeline anti-corrosion coating, which has been applied in many engineering projects.
