PE Mining Pipe

Raw material properties: High performance superconducting carbon black is used as an anti-static agent, decabromodiphenyl ether and antimony trioxide are used as flame retardants, and thoroughly mixed and plasticized into granules. The physical and mechanical properties of the pipes produced with this special material meet the PE-80 level water supply pipe standard, and the anti-static and flame retardant properties meet the requirements of the MT558.1-2005 standard of the Ministry of Coal Industry.

What is the definition of PE coal mine pipe?

A mining pipe made from polyethylene resin as the main raw material, with an appropriate amount of additives added, and extruded into shape. This type of pipe has outstanding anti-static and flame retardant properties, as well as high strength, good processing performance, strong environmental adaptability, excellent stress cracking resistance, and good creep resistance.

What are the raw materials for producing PE mining pipes?

The raw material is a special material made of PE resin with anti-static and flame retardant agents added.

What are the characteristics of PE mining pipe special raw materials?

The special raw material for PE mining pipes not only has long-term compressive strength, but also has resistance to slow stress cracking growth and rapid stress propagation. HE3490-LS is a special material for black PE100 pipes, which also has excellent anti sagging performance.

Product performance:

1. Flame retardant and anti-static: The anti-static and flame-retardant components of polyethylene pipes used in coal mines are evenly distributed in the pipe body, so the anti-static and flame-retardant performance indicators will not be affected by long-term use. The anti-static and flame retardant properties meet national standards and are suitable for specific locations underground that are flammable and explosive.

2. Lightweight and easy to install: Polyethylene pipes used in coal mines have a low density, with a unit weight of only 1/8 of steel pipes and 1/3 of fiberglass pipes. Therefore, polyethylene pipes used in coal mines are not only easy to transport and install, but also can greatly reduce the labor intensity of workers and improve work efficiency when used underground.

3. Corrosion resistance and non scaling: Polyethylene used in coal mines has strong corrosion resistance and non scaling properties, making it particularly suitable for underground transportation of high sulfur water and water containing calcium and magnesium ions. Greatly saving the cost of anti-corrosion and descaling, the service life is much longer than that of steel pipes, and the comprehensive economic benefits are high.

4. Self lubrication: The inner wall of polyethylene pipes used in coal mines is smooth, with low resistance when transporting fluids and much lower roughness than steel pipes and fiberglass pipes. Under the same conditions, the conveying capacity can be increased by 30%. Good flexibility and strong resistance to geological subsidence;

5. Good resistance to rapid cracking: Polyethylene pipes used in coal mines have good performance, are not easily brittle at low temperatures, and have good resistance to rapid cracking; Has good toughness and can absorb impact energy; The bending modulus is moderate, and the elongation at break is over 400%. Under special operating conditions such as geological subsidence that occur underground in coal mines, polyethylene pipes used in coal mines can avoid fracture accidents compared to traditional rigid steel pipes and fiberglass pipes.

6. Good wear resistance: Comparative tests on the wear resistance of polyethylene pipes and steel pipes used in coal mines show that the wear resistance of polyethylene pipes used in coal mines is four times that of steel pipes. In the field of coal transportation, compared with steel pipes, polyethylene pipes used in coal mines have better wear resistance, which means that polyethylene pipes used in coal mines have a longer service life and better economy.

7. Impact resistance: Polyethylene has a low low-temperature brittleness temperature and can be used at lower temperatures. 

8. High toughness: The elongation at break generally exceeds 500%. 

9. Good flexibility: The pipeline can be bent and used for offshore dredging pipelines, which can reduce rubber soft joints. 

10. Easy to connect: using hot melt connection, pipe clamp connection or flange connection, easy to construct.
