Along with the years of entrepreneurial journey of Zhongyuan people, she gradually formed her own spiritual pillar and behavioral norms. In the silent inheritance, she guided Zhongyuan Company towards a more brilliant tomorrow.
Enhanced 3PE anti-corrosion steel pipe is a corrosion-resistant steel pipe that is coated with 2 or 3 layers of polyethylene (3PE) on its outer wall to slow down or prevent the pipeline from being eroded and deteriorated by the chemical or electrochemical action of the external medium or the metabolic activity of microorganisms when used in different working environments. It consists of a three-layer structure, with the first layer being epoxy powder (FBE 100um), the second layer being adhesive (AD) 170-250um, and the third layer being polyethylene (PE) 1.8-3.7mm (reinforced grade). The three materials are integrated and firmly bonded with the steel pipe to form an excellent anti-corrosion layer.

Definition and Structure
Enhanced 3PE anti-corrosion steel pipe is a corrosion-resistant steel pipe that is coated with 2 or 3 layers of polyethylene (3PE) on its outer wall to slow down or prevent the pipeline from being eroded and deteriorated by the chemical or electrochemical action of the external medium or the metabolic activity of microorganisms when used in different working environments. It consists of a three-layer structure, with the first layer being epoxy powder (FBE 100um), the second layer being adhesive (AD) 170-250um, and the third layer being polyethylene (PE) 1.8-3.7mm (reinforced grade). The three materials are integrated and firmly bonded with the steel pipe to form an excellent anti-corrosion layer.
FEATURES
Good anti-corrosion performance
The 3PE anti-corrosion coating combines the high impermeability and mechanical properties of epoxy resin and polyethylene materials, and can effectively resist corrosion from soil, water, mold, etc. Ordinary steel pipes will corrode severely under harsh conditions, while reinforced 3PE anti-corrosion pipes can greatly extend their service life and can be used for about 30-50 years.
High mechanic strength
Clear regulations have been established on the carbon black content of certain specialized materials, ensuring the mechanical strength and temperature self-protection performance of the 3PE anti-corrosion layer. It also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly embedded in frozen soil.
Operational and production advantages
Easy to operate, high production efficiency, and high-quality rust removal, it is considered a high-quality pipeline external anti-corrosion technology internationally. Its own use of fusion welding connection ensures the integration of interface materials, realizes the integration of joints and pipes, and has good sealing performance. Compared with the pipe body, its interface has higher tensile strength, which can effectively resist the circumferential stress and axial stress generated by internal pressure, and there is no risk of leakage caused by joint distortion. The sealing performance is quite excellent.
Good electrical insulation
When used in conjunction with cathodic protection, the anti-corrosion coating should have a certain ability to resist cathodic peeling strength and good electrical insulation.
production process
On the 3PE anti-corrosion pre installation program, input the following steps in sequence: surface dust treatment of steel pipes, preheating of steel pipes, epoxy powder rolling or spraying, adhesive coating and polyethylene tape winding, circulating water cooling, cutting and leaving heads, and grinding of pipe ends. Finally, press the confirmation button, and the 3PE anti-corrosion equipment will process the anti-corrosion steel pipes in the above order. During production, adhesive coating and epoxy powder bonding are carried out simultaneously. When using lateral winding technology, it is necessary to ensure that the polyethylene in the overlapping part and the polyethylene rolls on both sides of the weld are tightly pressed.
