HDPE Pipe for Underground Coal Mining

Product features

A. Corrosion resistance: HDPE pipe for coal mining has high performance of anti-corrosion without the necessity of anti-corrosion treatment, to save cost. Its economy efficiency is 5~6 times of steel pipe, there, it is especially valuable for transporting high-sulfur water.

B. Excellent flow capacity: Highly smooth pipe wall and slight flow resistance to minimize scaling. Pipe has a perfect anti-scaling capacity; Scaling even will not occur in transporting water including calcium or magnesium to save de-scaling cost. Inner wall is smooth, its roughness is only 2/5 of steel to make a low flow resistance, and transporting capacity can be raised by 30% under same situation.

C. Safety: Excellent water tightness and environmental protection; Good joint connection; Easy handling; High safety and health performance with the raw material of HDPE resin; No pollution to environment; No harm to human; Environmental friendly; Non-toxic.

D. High strength: Supreme mechanical properties; Seldom embrittlement; Flexible to absorb impact; Good performance of rapid cracking resistance; Break elongation rate can be over 300%; Underground installation is seldom impacted by settlement.

E. Inflaming/static electricity resistance: Components of inflaming/static electricity resistance are distributed evenly in the pipe; Performance of inflaming/static electricity resistance will not be impacted by long-term service. Performance of inflaming/static electricity resistance is higher than national standards; Especially suitable for underground places of flammable and explosive.
