Large caliber 3PE anti-corrosion spiral steel pipe, high-strength corrosion-resistant pipe for municipal water supply and drainage gas transportation

Description :

This product is a high-performance 3PE anti-corrosion spiral steel pipe designed specifically for harsh outdoor and underground environments. The product adopts advanced three-layer polyethylene (3PE) anti-corrosion technology, which perfectly combines epoxy powder, adhesive and polyethylene outer layer to form a dense protective barrier. This structure not only inherits the high adhesion and chemical corrosion resistance of epoxy resin, but also combines the excellent mechanical strength and impact resistance of polyethylene layer, which can effectively resist soil stress, plant root penetration, and mechanical damage during construction.

From the picture, it can be seen that this series of steel pipes has a large diameter, thick pipe walls, and spiral weld characteristics on the surface, indicating that they are manufactured using double-sided submerged arc welding spiral welding technology, ensuring the overall strength and pressure bearing capacity of the pipe body, and are particularly suitable for long-distance pipeline engineering. The inner and outer surfaces of the steel pipe are smooth and even in color, demonstrating good quality of anti-corrosion coating.

This product is widely used in key fields such as urban municipal water supply and drainage pipelines, natural gas transmission trunk lines, petrochemical pipelines, and seawater desalination projects. Its excellent corrosion resistance can significantly extend the service life of pipelines to over 50 years and significantly reduce maintenance costs in the later stages. For engineering projects that require crossing complex geological conditions or highly corrosive environments, 3PE anti-corrosion steel pipes are an ideal choice to ensure transportation safety and prevent medium leakage. The target customer group includes municipal engineering contractors, petrochemical companies, water companies, and large-scale infrastructure construction units. We provide customized specification services and can adjust the pipe diameter, wall thickness, and anti-corrosion level according to project requirements to ensure that every pipeline meets national standards and industry specifications.
