Coal Mine Waste Gas Drainage Pipe machine is developed by Goldstone based on the normal polyethylene corrugated pipe.

The innovated reinforced corrugated pipe provide the steel reinforced structure
definitely   Antistatic, flame retardant;In the mean time, the weight of the pipe has been obviously reduced.

The pipe diameter could be ranged from 300mm to 800mm.

The pipe has innovated three layers wall structure. The steel reinforced layer is
in the middle structure to provide the high stiffness.and either the inner layer
or outer layer is formed by high-density polyethylene that protects the pipe out of corrosion.

And there is a super bond medium between steel and polyethylene which integrate them tightly into one piece. The waste gas could be drainaged sufficiently without the any residue in the inner pipe.
