The 3pe reinforced anti-corrosion spiral steel pipe structure has three layers: the first layer is epoxy powder, the second layer is adhesive, and the third layer is polyethylene. The three materials are integrated and firmly bonded with the steel pipe to form an excellent anti-corrosion layer.

Advantages of 3pe reinforced anti-corrosion spiral steel pipe:

1. 3PE anti-corrosion steel pipes have extremely high sealing performance, and long-term operation can greatly save energy, reduce costs, and protect the environment.

2. Strong corrosion resistance, quick construction, and a service life of up to 30-50 years.

3. PE also has good corrosion resistance and impact resistance under low temperature conditions, with low water absorption rate.

4. Simultaneously possessing high epoxy strength, low water absorption of PE, and good flexibility of hot melt adhesive, it has high anti-corrosion reliability. The characteristics of this anti-corrosion are simple production process, good anti-corrosion effect, and low price. It is a widely recognized anti-corrosion method in the pipeline manufacturing industry. 2. Three layer polyethylene (3PE) steel pipe anti-corrosion for oil and gas, two-layer polyethylene (2PE) steel pipe anti-corrosion, standard: SY/T0413-2002; DIN30670。
