The outer wall of 3PE anti-corrosion steel pipe is protected by a three-layer structure polyethylene (3PE) anti-corrosion coating.Its base material includes seamless steel pipe, spiral steel pipe and straight seam steel pipe.
The three-layer polyethylene (3PE) anti-corrosive coating has good corrosion resistance, moisture permeability resistance and mechanical properties.
1. Structure composition
The outer anti-corrosion layer of 3PE anti-corrosion steel pipe is usually composed of three layers:
the first layer is epoxy powder;
the second layer is adhesive (AD);
the third layer is polyethylene (PE).
2. Performance advantage
3PE anti-corrosion steel pipe has strong corrosion resistance, and also has good corrosion resistance and impact resistance under low temperature conditions.
The water absorption rate of the coating is low (less than 0.01%), the epoxy strength is high, the PE water absorption is low, the hot melt adhesive has good softness, and has high anti-corrosion reliability.
3. Anticorrosion principle
The first layer of epoxy powder coating is directly bonded to the surface of the steel pipe, and has good chemical corrosion resistance and cathode stripping resistance.
The copolymer adhesive in the middle layer reacts with the epoxy groups of the epoxy powder coating to form hydrogen bonds or chemical bonds through polar functional groups, ensuring that the overall anti-corrosion layer has good bonding at higher temperatures.
The polyethylene surface layer mainly plays the role of mechanical protection and anti-corrosion, and the traditional two-layer structure polyethylene anti-corrosion layer has the same role.
4. Application field
3PE anticorrosive steel pipes are widely used in natural gas pipelines, oil transmission pipelines, chemical and pharmaceutical, printing and dyeing industries to transport corrosive media process pipelines, as well as sewage treatment discharge pipes, sewage pipes and biological pool anticorrosion engineering, agricultural irrigation pipes, deep well pipes, drainage pipes and other networks.
