Specifications

focus on energy saving and environmental protection products.

Underground Coal mine coating composite steel pipe is using the special processing, inner steel pipe, coating a special polyethylene plastic powder or epoxy resin powder material on the surface ,it's antistatic, flame-retardant, anti-corrosion properties of composite products, the product are overcome to rust, corrosion, high pollution dyes and plastic pipe of low strength, and easy deformation and other defects, it has both advantages of steel and plastic products, which are focus on energy saving and environmental protection products.

Performance characteristics

 

1. high pressure bearing, good mechanical performance

 

2. strong chemical corrosion resistance
