HDPE methane extraction pipes

HDPE methane extraction pipes are special pipes used to extract methane gas from coal mine gas (coal bed methane). Coal mine gas, also known as coal bed methane, is mainly composed of methane and is a high-quality clean energy source. In coal mines, gas extraction is an important safety and production link. The gas is extracted through special pipes to ensure the safety of mine operations. The performance of these pipes directly affects the safe production of coal mines, and therefore plays a vital role in coal mine production. In addition, the design and construction of methane extraction pipelines need to take into account safety and efficiency to ensure the effective extraction of methane while ensuring the safety of workers.

Application field

The surface of HDPE pipes is generally white, and if other impurities are added during the production process, they may appear in different colors. The various physical and chemical properties of this pipe make it widely used in municipal engineering, agricultural irrigation, petrochemical, mining engineering, water supply and drainage engineering and other fields. Particularly in methane extraction applications, the durability and reliability of HDPE pipe is critical to ensuring the safe and efficient delivery of methane.‌

JUNNUO HDPE methane extraction pipe has the characteristics of antistatic, flame retardant, impact resistance, high strength, good flexibility, corrosion resistance, wear resistance, light weight, long service life, convenient installation and low overall cost. JUNNUO HDPE is the best solution for coal mine methane extraction pipes.

HDPE methane extraction pipe is made of high quality PE80 or PE100 raw material, the size range is 20-1200mm, and the performance is in accordance with ISO4427 standard. For coal mines or underground gas drainage HDPE pipes can be manufactured with five rated pressures: SDR11-PN16 bar, SDR13.6-PN12.5 bar, SDR17-PN10 bar, SDR21-PN6 bar, SDR26-PN6 bar, etc.                                                                                                                                                                                                                                       

• 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 0.03 mm, and the roughness of the steel pipe and the glass pipe is greater than 0.06 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.
