Product Description 

Transportation: Pipes are indispensable for the efficient long-distance transportation of oil, gas, and a variety of other essential commodities. Large-diameter transmission pipelines are critical in transferring crude oil, natural gas, and refined products from their production origins to refineries, processing facilities, and key distribution hubs.

Epoxy & Plastic Coated Anti-Corrosion Steel Pipe: Engineered to withstand diverse working conditions, these adaptable pipes can be customized with an array of robust anticorrosive solutions. Ideal for buried installations, trenchless traction, pipe jacking, and open-air applications, available anticorrosion solutions include:
- Buried: Inner epoxy with outer PE, inner epoxy with outer 3PE, inner epoxy with outer 3PP, and fully coated with inner & outer epoxy.
- Pipe Jacking: Inner epoxy with outer 3PE, inner epoxy with outer 3PP, and inner epoxy complemented by double-layer epoxy.
- Trenchless Traction: Inner epoxy paired with outer 3PE, inner epoxy paired with outer 3PP, and inner epoxy paired with double-layer epoxy.
- Open-Air Application: Inner epoxy with an outer anti-UV coating.

Inner Epoxy Resin Outer Polyethylene Coating Composite Steel Pipe: This meticulously pre-treated steel pipe boasts an inner surface shielded with fusion-bonded epoxy powder and an outer surface fortified with polyethylene powder. The outcome is a high-performance, corrosion-resistant steel-plastic composite product.
