Characteristics Of Ultra High Molecular Weight Polyethylene Wear Resistant Pipe

May 21, 2019

1, high wear resistance

Ultra-high molecular weight polyethylene wear-resistant pipe has excellent wear resistance, and its wear resistance is 4-7 times that of Q235 pipe and 2.7 times that of 16-manganese steel wear-resistant pipe. The excellent wear resistance greatly increases the conveying capacity of the pipe and prolongs the service life of the pipe. Under the same conditions, its service life is more than three times that of the traditional steel wear-resistant pipe.

2, impact resistance

The impact resistance of ultra-high molecular weight polyethylene wear-resistant pipes is 5 times that of ordinary polyethylene pipes, twice that of polycarbonate and 10 times that of polytetrafluoroethylene. The good impact resistance makes it able to withstand the huge water hammer impact formed when the pumping station is opened during construction.

3, low energy consumption

Ultra-high molecular weight polyethylene wear-resistant pipe has high self-lubricity and non-adhesion, the friction coefficient is only 0.009, and the friction coefficient of steel pipe is 0.013. The medium-conveying flow rate of the ultra-high molecular weight polyethylene wear-resistant pipe of the same caliber is greater than that of the steel wear-resistant pipe. At the same flow rate, the use of ultra-high molecular weight polyethylene wear-resistant tubes saves 25%.

4, no scaling

Due to the smooth inner wall of the ultra-high molecular weight polyethylene pipe, the roughness is only Ra0.00022, which can effectively reduce the fouling of the pipe wall during the long-term transportation of the wear medium stone sand, and does not need to do the wall cleaning and descaling maintenance work. Significant savings in daily maintenance costs.

5, low temperature resistance

Ultra-high molecular weight polyethylene wear-resistant pipe has excellent low-temperature resistance, and can maintain its mechanical properties at a low temperature of minus 70 °C. It is particularly suitable as a conveying pipe for wear media in cold regions.

6, high pressure

Ultra-high molecular weight polyethylene wear-resistant pipe has high pressure and high toughness, tensile strength is twice that of PE100, 2.5 times that of PE80, and can withstand large fluctuations in internal pressure during media transportation.

7, maintenance-free

Because the ultra-high molecular weight polyethylene wear-resistant pipe has the characteristics of wear resistance, corrosion resistance, frost resistance and anti-fouling, the pipe does not need to be rust-proof, anti-freeze, descaling and other routine maintenance after running the pipe, which can save more than 95% of maintenance costs. .

8, high environmental protection

The production and processing of ultra-high molecular weight polyethylene wear-resistant pipes is a low-carbon environmental protection industry. The CO2 emissions from the production process are low, only 15% of the carbon dioxide emissions from the production of steel. There is no waste water, waste gas and waste residue; the production process is 20% more energy efficient than traditional steel products.

9, high toughness

The ultra-high molecular weight polyethylene wear-resistant pipe has good toughness and elongation ≥350%. When the application environment is settled, the pipe and the interface are not easy to crack, and the normal transportation of the medium is ensured to a large extent.
