PE Mining Pipe, PE Gas Drainage Pipe, PE Mining Permeation Pipe, Large-diameter PE Mining Pipe, PE Mining Pipe, PE Wear-resistant Mining Pipe
1. Super strong impact resistance, more suitable for harsh environments underground in coal mines:
The impact resistance ranks first among plastics, and it is difficult for them to crack due to strong external impact or internal pressure fluctuations. Its impact strength is 10 times that of nylon 66, 20 times that of polyvinyl chloride, and 8 times that of polytetrafluoroethylene; Compared to ordinary polyethylene, it has an impact strength four times higher, especially in low-temperature environments, where its impact strength reaches a certain value. Its flexibility provides an extremely strong guarantee for the conveying system.
2. Wear resistance:
Among all current engineering plastics, UHMW-PE has the highest wear resistance, which is remarkable. The higher the molecular weight of the material, the more wear-resistant it is, even surpassing many metal materials such as carbon steel, stainless steel, bronze, etc. The service life under strong corrosion and high wear conditions is 4-6 times that of steel pipes and 9 times that of ordinary polyethylene; And it also improves the conveying efficiency by 20%.
3. Good tensile performance:
The tensile strength reaches 22-28MPa, and the elongation at break is over 400%.
4. Corrosion resistance:
UHMWPE has high chemical stability. Except for some strong oxidizing acids that can corrode slightly at high temperatures, other acidic and alkaline solutions are not easily corroded and resistant to aging.
5. Extremely low friction coefficient, low fluid resistance:
The pipe wall has high smoothness and low friction coefficient.
6. Not easy to scale:
The surface adsorption force of UHMW-PE is very weak, and its anti adhesion ability is strong, so the surface of the pipe is not easy to adhere and scale with other materials.
7. Easy connection:
It can be directly flanged and connected on the mother body without welding the pipe fittings, avoiding the phenomenon of breakage due to poor welding of the pipe fittings and saving the cost of pipe fittings. Ordinary PE pipe flange connections are prone to U-turns
8. Stable flame retardant and anti-static performance:
The flame retardant and anti-static properties are good and meet the standard requirements.
