Coal mine polyethylene pipe

Mine gas drainage PVC pipe Features: 1, flame retardant, anti-static: the use of advanced three-layer co-extrusion molding process, the antistatic performance only lasted for a long time, and flame retardant, antistatic effect and safety performance is much better than coating, and other pipes attached. 2, corrosion resistance, transmission fluid resistance: no knot strong, outer wall smooth, fluid resistance, particularly suitable for underground transport water quality sulfur ions, calcium and magnesium. 3, light weight, easy to install: density per unit weight of steel is only 1/5, 1/3 glass, easy to install, can greatly reduce the labor intensity. Improve work efficiency. 4, anti-aging: After aging test tube, impact resistance reaches (MT558.2-2005) requirements, with good toughness, not brittle, can effectively prevent breakage accident. 5, long life, cost-effective: maintenance-free, saving the costs of post-cleaning corrosion, life is much higher than steel, overall economic efficiency is 6-8 times that of steel.
