Product Description
Transportation: Pipes are crucial for transporting oil, gas, and related products over long distances. Large-diameter pipelines, known as transmission pipelines, are used to transport crude oil, natural gas, and refined products from production fields to refineries, processing plants, and distribution centers.
Epoxy & Plastic coated anti-corrosion steel pipe can adopt a variety of anticorrosive solutions to meet the needs of different working conditions. Applicable to buried, trenchless traction, pipe jacking and open-air applications and other environmental conditions, the following anti-corrosion solutions can be used respectively:
- Burried:inner epoxy outer PE,inner epoxy outer 3PE,inner epoxy outer 3PP,inner & outer epoxy coated
- Pipe Jacking:inner epoxy outer 3PE,inner epoxy outer3PP,inner epoxy outer double layer epoxy
- Trenchless traction:inner epoxy outer 3PE,inner epoxy outer 3PP,inner epoxy outer double layer epoxy
- Open-air application:inner epoxy outer anti-uv coated

Inner epoxy resin outer polyethylene coating composite steel pipe is a pre-treated steel pipe as the base pipe, pipe heating in its inner surface coated with fusion bonded epoxy powder, the outer surface of the polyethylene powder coated with a corrosion-resistant steel-plastic composite products made of performance.
Connection Method





Good compatibility, convenient connection
The inner and outer layers of the double-layer epoxy are epoxy resin coating based on epoxy resin, and the compatibility of the two is good. The solvent-free epoxy coating is used for patenting, which has good compatibility and excellent corrosion resistance.
Good cathodic protection
The double-layer epoxy coating has good compatibility with the cathodic protection and will not shield the cathodic prot


Good flexibility and resistance to bending
The coating material is made of epoxy resin with high molecular weight, which has good flexibility and excellent bending
Scratch Resistance
The outer layer is modified epoxy coating with special scratch material, which has excellent scratch resistance.

High Temperature Resistant
Double-layer epoxy anticorrosive steel pipe can withstand a maximum temperature of 110ºC.
