3. The only one in the country set large-caliber steel pipe, anti-corrosion processing, anti-corrosion materials allproduced in one enterprise.
Product Description

Internal Epoxy External Double-layer Epoxy Coated Pipe
The High-quality steel pipe is used as the base pipe,and a layer of expoxy resin material is coated on the inner and outer surfaces of the pipe through the thermal fusion process.

Product Parameters
Product Features
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




Good compatibility and easy mending
Double-layer epoxy inner and outer layers are both epoxy resin-based resin coating, the two are compatible with each other, patching using solvent-free epoxy coatings, good compatibility.
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.
Connection Method

The flexible cap and insert coated plastic steel pipe is based on high-quality steel pipe, one end of the pipe is bevelled, one end is flaring, and then coated with plastic. The T-shaped rubber ring with the same structure as the spherical ink pipe is directly connected with the cap and insert. On the basis of retaining the advantages of coated steel pipe, it inherits the advantages of fast and reliable connection of ductile iron pipe flexible socket and socket, and complements the advantages of the two. And the two advantages complement each other.
