Mining pipe performance introduction Edit 1, excellent impact performance, more suitable for the harsh environment of coal mines:
Shock resistance of the first plastic, whether it is strong external shocks,or internal pressure fluctuations, are hard to make it cracking. The impact strength is 10 times that of nylon 66, 20 times PVC, 8 times PTFE; 4 times higher than normal polyethylene impact strength, especially in the low temperature environment, the impact strength but reached the highest value, Its flexible properties provide extremely safe and reliable conveyor system.
Impact properties with other materials comparison table:
material | UHMWPE | HDPE | PA66 | PC | ABS |
Impact strength kJ / m ² | 130 | 37 | 8 | 80 | 15 |
2, Wear resistance:
UHMW-PE in the current engineering plastics in the highest wear-resistant plastic crown, the most eye-catching.The higher the molecular weight, the more wear-resistant the material is and more than many metallic materials (carbon steel, stainless steel, bronze, etc.). In the strong corrosion and high wear conditions, the service life of steel pipe is 4-6 times that of ordinary polyethylene 9 times; and improve the delivery efficiency of 20%.
3, good tensile properties:
Tensile strength of 22 ~ 28MPa,elongation at break of more than 400%.
4, corrosion resistance:
High chemical stability of UHMWPE, in addition to some strong oxidizing acid can be slightly corrosive at high temperatures, the other acid-base corrosion is not easy, anti-aging.
5, a very low coefficient of friction, fluid resistance is small:
Pipe wall finish, low coefficient of friction.
6, not easy scaling:
UHMW-PE surface adsorption is very weak, anti-adhesion ability, so the pipe surface is not easy to adhere to other materials, not easy to scale.
7, easy to connect:
Can be directly flanged on the parent flange connection, no longer welding pipe fittings, to avoid the tube due to poor welding and fracture phenomenon, can save the cost of pipe fittings Ordinary PE pipe flange to connect easily turn.
8, flame retardant, antistatic properties and stability:
Flame retardant, antistatic performance is good, have reached the standard requirements.
9, long service life:
Downhole life of more than 20 years, significant economic benefits.
