- Buried: Inner epoxy with outer PE, inner epoxy with outer 3PE, inner epoxy with outer 3PP, and inner & outer epoxy coated combinations ensure maximum durability.
- Pipe Jacking: Inner epoxy with outer 3PE, inner epoxy with outer 3PP, and inner epoxy with double-layer epoxy coatings ensure optimal performance.
- Trenchless Traction: Inner epoxy with outer 3PE, inner epoxy with outer 3PP, and inner epoxy with double-layer epoxy coatings provide superior resilience.
- Open-Air Application: Inner epoxy with outer anti-UV coated solutions offer excellent protection against the elements.
Inner Epoxy Resin Outer Polyethylene Coating: This composite steel pipe starts with a pre-treated steel base, followed by heating and coating the inner surface with fusion-bonded epoxy powder. The outer surface is then coated with polyethylene powder, creating a high-performance, corrosion-resistant steel-plastic composite product engineered for maximum longevity and durability.

| Product Features |
The inner and outer layers of our double-layer epoxy tubing feature an epoxy resin coating, ensuring superior compatibility. This solvent-free epoxy coating, which is patented, offers exceptional corrosion resistance.
Our double-layer epoxy coating harmonizes excellently with cathodic protection systems, ensuring no shielding of the cathodic protection.
Crafted from high molecular weight epoxy resin, our coating material boasts remarkable flexibility and superior resistance to bending.
The outer layer, a modified epoxy coating with special scratch-resistant materials, provides outstanding scratch resistance.
Our double-layer epoxy anticorrosive steel pipe withstands temperatures up to an impressive 110ºC.
