3PE anti-corrosion steel pipe


The basic materials of 3PE anti-corrosion steel pipe include spiral steel pipe, seamless steel pipe and straight seam steel pipe. Three layers of polyethylene (3PE) anti-corrosion layer, good anti-corrosion performance. It has been widely used in the oil pipeline industry due to its good water and gas permeability and mechanical properties. 

The surface of the 3PE anti-corrosion steel pipe has been pretreated by different pretreatment methods, and all the steel pipes are under pressure. Application of circulating anti-corrosion steel pipe: The basic material of anti-corrosion steel pipe is spiral pipe, straight seam pipe, seamless pipe, etc., which are widely used in petroleum, chemical, natural gas and other industries. Thermal power, sewage treatment, water source, bridge, steel structure, seawater transportation pile and other pipeline engineering fields, suitable for high-rise building water supply, heating network heating and self-support. 

The processing method of 3PE anti-corrosion steel pipe is generally divided into winding type and round mold packaging type. At present, countries all over the world attach great importance to the research on corrosion control. Many achievements have been made in the field of pipeline anti-corrosion coatings. There are no new materials and techniques.   

3PE anti-corrosion steel pipe is the anti-corrosion form of underground long-distance pipeline. The outer wall adopts hot-melt winding technology to form three layers of epoxy resin anti-corrosion layer at the bottom, with adhesive in the middle and polyethylene anti-corrosion layer on the outside. The inner wall adopts thermal spray epoxy powder anti-corrosion method. The powder is heated and melted at high temperature and uniformly coated on the surface of the tube to form a steel-plastic alloy layer.
