SSPE Polyethylene composite pipe

Polyethylene (PE) pipes used in coal mines are made of polyethylene as the main raw material, mixed with high-quality conductive carbon ink and flame retardant, and processed by one-time extrusion molding through a proprietary technology. The quality of its products meets the requirements of the national standard GB/T13663-2003 polyethylene pipes for water supply and the industry standard MT558.1-2005 polyethylene pipes for underground coal mines. The safety performance meets the requirements of MT181-88.

1. Light weight, long life, and convenient construction: the weight of the pipe is light, only 1/8 of the steel pipe, but the service life is 4 to 5 times that of the steel pipe. It is convenient to transport and install, especially in the underground, which can greatly reduce the labor intensity of the workers and improve the work. effectiveness.

2. Strong corrosion resistance: The pipe has strong corrosion resistance, strong non-scaling property, no anti-corrosion treatment, and saves related costs. The comprehensive economic benefit is 5-6 times that of steel pipes, especially suitable for underground gas transportation. gas.

3. Self-lubricating: The pipe wall has high smoothness, low fluid resistance and not easy to scale. The pipe has strong anti-scaling ability, and it is not easy to scale when used underground, which can save a lot of descaling costs. The inner wall is smooth, the roughness is 2/5 of the steel pipe, and the conveying resistance is small. Under the same conditions, the conveying capacity can be increased by 30%.

4. Good water tightness and environmental protection. The construction is convenient, and the flange connection is adopted, which is simple and quick, safe and leak-free. The pipes are well-joined and convenient for construction. The raw material is PE resin, which has good hygienic performance, no pollution, harmless to workers, green environmental protection, clean and non-toxic.

5. Good wear resistance, high strength, impact resistance, and superior mechanical properties: The comparison test of the wear resistance of polyethylene pipes and steel pipes for coal mines shows that the HDPE resin used in polyethylene pipes has a wear resistance of 5 ~6 times. Good aging resistance, not easy to embrittlement, good crack resistance; good toughness, can absorb impact energy, good resistance to rapid cracking; moderate flexural modulus, and elongation at break can reach more than 300%. In coal mines, under special operating conditions where geological subsidence and other phenomena occur from time to time, compared with traditional rigid pipes, polyethylene pipes used in coal mines can effectively avoid fracture accidents, and installation is less affected by terrain subsidence. This means that polyethylene pipes used in coal mines have a longer service life and good economic benefits.

6. Flame retardant and antistatic. The antistatic and flame retardant components are evenly distributed in the pipe body, so the antistatic and flame retardant properties will not be affected by the long use time. The antistatic and flame retardant properties are in line with national standards, and are suitable for specific places that are flammable and explosive underground.
