Gas Drainage Pipes:

0.6 Mpa Coal Seam Flame Proof Gas Drainage Pipes

1. retardant antistatic

mining of high-strength PVC pipe through a unique formula designed to make the product antistatic, flame retardant over China MT558.2-2005 standard specifies the technical indicators that antistatic agents and flame retardant agents will not be used for a long time precipitation occurred, dual resistance constant, lasting for underground gas drainage and other flammable places.
2. high strength, anti-aging

Coal Mine high strength PVC pipe through technical innovation, quality upgrading, thus solving the PVC pipe brittle hair and the problem of poor impact resistance, good toughness and resistance to aging, which can effectively absorb impact energy, and coal have been peer beyond standard forefront.
3. lightweight and easy disassembly

Coal Mine with PVC pipe because of light weight (per unit weight of steel is only 1/5), not only to transport, easy accessibility, but also greatly reduce the labor intensity, and save a lot of installation costs and time.
4. corrosion, fouling, long service life

Factory produced the coal mine with PVC pipe corrosion resistance, no scaling, long life, overall economic efficiency is 6-8 times that of steel, can greatly save material and maintenance costs during use.
5.  friction is small

mining of high-strength PVC pipe wall is smooth without fouling, transmission fluid friction is small, the same conditions, the output capacity 30% higher than steel.
6. easy maintenance and replacement after damage

As the mine complex conditions, no matter what material the pipes are likely to encounter some damage, and steel pipe, PE pipe and some pipe compared to mine high-strength PVC pipe application-specific solvent adhesive repair time is short, the effect is good, replaced by more simple and convenient, no security risks.
