Product Description
3LPE anti-corrosion steel pipe is composed of three distinct layers:
- First Layer: Epoxy powder
- Second Layer: Adhesive
- Third Layer: Polyethylene
Advantages of 3LPE Pipe Coating
- High Sealing Performance: The 3LPE coating offers exceptional sealing capabilities, significantly reducing energy costs and promoting environmental protection over prolonged use.
- Durability: It provides strong corrosion resistance, is easy to install, and has a service life of 30-50 years.
- Low-Temperature Performance: The coating maintains good corrosion and impact resistance even in low temperatures, with polyethylene exhibiting low water absorption.
- Reliability: High epoxy strength, combined with the softness of the hot melt adhesive, ensures excellent anti-corrosion reliability. The production process is straightforward, resulting in effective corrosion protection at a low cost.
