Polyethylene pipes for coal mines, PE pipe fittings for coal mines are special environmental protection plastic pipes, applied to pressure and non-pressure pipelines that have flame retardant and anti-static requirements for products. In terms of light weight, corrosion resistance, and convenient construction, the material used is special polyethylene pipe material for coal mines, which can meet the special requirements of users.

According to the national coal industry standard MT588. 1-2005 (plastic pipe under the mine the first part of the polyethylene pipe), MT181-88 "Safety Inspection for Plastic Pipes under the Mine", AQ1071-2009 "Safety Technology for Non-metal Gas Pipes Used in Coal Mines The requirements of the "Requirements" organization of production and testing, and access to coal mines with polyethylene pipe [MA] coal mine safety signs.

This is the Standard we get in China markets.

HDPE underground mining pipes for gas/ methane drainage pipes can be used for water supply, exhaust, pressure, shotcrete and gas discharge in coal mine underground below 40 °C.

 

 

applications

Gas explosion is the most common accident in coal mine accidents. In order to ensure safe production, all coal mine companies and departments pay more attention to the research on gas drainage. The most commonly used measure in coal mine production is to extract gas through special pipelines. To make sure the safety of mine operations. Gas pipelines are customized pipelines for gas drainage in coal mines. The performance of gas pipelines directly affects the safety production of coal mines. It can be seen that the performance of gas drainage pipelines has a major impact on the safe production of coal mines.

Because of the special underground environment of the coal mine, which determines that the mining pipelines must have the basic characteristics of antistatic and flame retardant. Besides, due to the presence of acidic or alkaline solutions in coal mines, it is highly corrosive. So underground Gas drainage PE pipes must have acid and alkali resistance if work under the mine for a certain time. On the other hand, due to the landslide possibility under the mine road or mine collapse in mines, etc., the pipeline must have the characteristics of impact resistance and extrusion resistance.

The inner and outer walls of the polyethylene gas drainage pipes are covered with a high impact, high flame-retardant, antistatic polymer material layer. The inner wall of the pipe adopts a special antistatic agent produced by our company so that Underground Gas drainage pipes not only have strong impact resistance. Performance and anti-negative pressure performance, but also to ensure the pipeline in the coal mine meet the fire-retardant and anti-static requirements. The Underground Gas drainage pipelines break through the manufacturing technology and connection technology of large-diameter gas drainage pipes with diameters DN500MM and above, we provide the mining industry with a high strength, antistatic, high flame retardance, corrosion resistance, light weight, easy handling, and easy installation for large diameter pipelines.

Polyethylene gas (methane) drainage pipe applications:

1. Underground gas drainage pipes in coal mines.
2. Ventilation pipes in underground coal mines.
3. Flame-retardant pipe.
4. Antistatic piping.
5. Negative pressure piping.
6. Road and railway, tunnel ventilation, water drainage and methane drainage pipelines, etc.

advantages

HDPE Pipes For Underground Coal Mine Gas/Methane Drainage have outstanding antistatic and flame retardant properties, but also have the advantages of high strength, good processing performance, strong environmental adaptability, excellent stress crack resistance, and good creep resistance.

1. Quality guarantee: HDPE, made of PE resin, is flame retardant, antistatic, high impact, and environment friendly, which can provides better security assurance to workers.  

2. Light weight and easy installation: Low density of HDPE pipes used in coal mine makes its unit weight smaller, only 1/8 of steel pipes, 1/3 of FRP pipes.

3. Anti-aging and fast-crack resistance: The PE pipes used in coal mines have good properties of anti-aging, embrittlement, good toughness and high impact. With good impact resistance, its elongation rate is more than 200% , avoiding rapid cracking and breakage accidents.

4. Corrosion resistance and no layer:The PE pipes used in coal mines are highly resistant to corrosion and dirt, saving costs of corrosion protection and descaling.

5. Smooth inner face: The inner face is very smooth which gives PE pipes small resistance and distribution ability.
