3PE anticorrosive steel pipe base materials include seamless steel pipe, spiral steel pipe and straight seam steel pipe. Anti-corrosion pipelines can be divided into two categories, lined with anti-corrosion steel pipes and outer-wall anti-corrosion steel pipes. The lining anti-corrosion mainly includes cement mortar-lined anti-corrosion steel pipe, which has more applications and lower cost. The cement mortar-lined anti-corrosion steel pipe uses the cement mortar anti-corrosion layer to protect the pipeline. Outer wall anti-corrosion pipes are more commonly used 3pe anti-corrosion pipes. The anticorrosion technology is a process of covering the outer wall or inner wall of the steel pipe with a protective effect on the pipeline itself. It can process various pipes such as straight seam steel pipe and spiral steel pipe. Among them, in order to prevent accidents such as personal injury, loss of property, etc. caused by explosion when conveying flammable and toxic fluids, Spiral Steel Pipe Plant adopts corresponding process standards to continuously meet important performance operations, and ensure quality and safety in the market during testing and measurement Use.
2PE anti-corrosion steel pipe: two layers of PE anti-corrosion structure for pipelines, the first layer of polyethylene (PE), the second layer of adhesive (AD), the two materials are fused together, and the thickness of each layer is the same as that of three layers of PE.
2PE anticorrosive steel pipe advantages:
1. Strong corrosion resistance, the construction side is simple and fast, and the service life can reach 30-50 years.
2. 2PE anti-corrosion steel pipe has extremely high tightness, long-term operation can greatly save energy, reduce costs and protect the environment.
3. At the same time, it has high epoxy strength, low water absorption of PE and good softness of hot melt adhesive, etc., and has high corrosion resistance.
4. It also has good corrosion resistance and impact resistance under low temperature conditions, and the water absorption of PE is low (less than 0.01%).
