- The flame retardant and antistatic properties are stable: The flame retardant and antistatic properties are stable, and the flame retardant and antistatic properties are not lost due to long use time.
- Corrosion resistance: Polyethylene material can withstand the erosion of a variety of chemical media, no chemical corrosion, suitable for coal mine gas and water supply.
- Flow resistance: The inner wall roughness of the pipe is not more than mm, and the roughness of the steel pipe and the glass pipe is greater than mm. This can reduce energy consumption and save energy.
- Excellent flexibility: Pipes can be coiled and supplied in longer lengths, avoiding a large number of joints and fittings, saving pipeline construction costs.
- Good resistance: With good resistance to rapid crack propagation, excellent scratch resistance and environmental stress cracking performance.
- Long service life: The pipeline is used stably and has a life span of 70 years.
- Light weight: convenient transportation and installation.
It is suitable for methane extraction in coal mines with normal temperature not exceeding 60 °C, water supply, exhaust, pressure, spray and other places. The pressure of the pipe is up to 1.6 Mpa.
