Epoxy Coated Steel Pipe
The epoxy coated steel pipe is widely applied in the petroleum, natural gas, chemical engineering, sewage disposal, bridge piling, and other fields. It is made by spraying epoxy powder onto the surface of an ordinary steel pipe. The fusion bonded epoxy coating is pollution-free and it has good resistance to impact, bending, and high temperature.

The epoxy powder is a kind of thermosetting and non-toxic paint. After curing, it can form the high molecular weight crosslinked coating which features excellent chemical corrosion resistance and high mechanical property, especially outstanding abrasion resistance and adhesion power. This kind of paint is 100% solid with no solvent and pollution. The powder utilization rate is 95% or higher. Hence, the epoxy coating is ideal for buried steel pipe.
Product Usage
1. The epoxy coated steel pipe is successfully applied in the Shanghai Yangtze River Bridge project. This sets a precedent for the application of fusion bonded epoxy powder coating technology in the external corrosion protection of large diameter steel pipe piles.
2. The fusion bonded epoxy powder coating for large diameter steel pipe pile realizes industrialization and automation, free from the impact of human factors and weather factors. The pass rate of first coating reaches 100%, which is superior to that of other processes.
