UHMWPE管疏浚和填

The characteristic of UHMWPE pipes Anti-abrasion: the abrasion value of UHMWPE pipe is 1/4 of steel pipe, 1/3 of HDPE pipe under same working conditions. Water hammer resistance: UHMWPE pipes have strong enduring capability to the impacts from various sands, mud and slurries. Corrosive resistance: Higher structure stability, corrosion resistant to various chemical mediators. No electrochemical corrosion, no need anti-corrosive coating. Self-lubrication: The roughness of UHMWPE is 0.00022mm. The pressure loss of UHMWPE pipe is 1/10 of steel pipes, 1/7 of nylon pipes. Over 20% of transfer efficiency will be increased. Non-scaling: the internal wall is very smooth, preventing the fouling on the wall and no influence to the production efficiency. Light weight: the density of UHMWPE pipe is only 1/8 of steel pipe. It is easy to move and install, especially suitable for the working sites at where the lifting machines could not work. Easy connection: flanges are available to connect the pipes, no need washers. The installation will be very easy and fast. There are no dangers and concerns of water leakage. Anti-aging: the UHMWPE pipes will not be aging in 50 years under hot sunlight, and it could work over 100 years if buried underground. Environment friendly: UHMWPE pipe is nontoxic, no bacteria, and no pollution to environment.Low carbon: the discharge of carbon dioxide during UHMWPE pipe production is only 15% of steel pipe production, which is good for environment protection.Temperature Resistance: UHMWPE pipes could be used under the temperature of -70°C—80°C, and there is no deformation.Long working life: the working life of UHMWPE pipe is 4 times longer than steel pipe under same working condition.
