Why is UHMWPE Pipe Good Liquidity?

Pulished on Jun. 20, 2020

As a High Flexibility UHMWPE Pipe Manufacturers, share with you. Ultra-high molecular weight polyethylene pipes have better wear resistance than PTFE, nylon, carbon steel and other materials, making them widely used in metallurgical mines, power, dredging and dredging, oil, natural gas, textile, paper, food, chemical, mechanical, electrical and other industries. The ultra-high molecular wear-resistant pipes are extruded using ultra-high molecular weight polyethylene resin with a molecular weight of about 2.5 million. UHMWPE is a kind of polymer compound, which has super wear resistance, self-lubricity, high strength, stable chemical properties and strong anti-aging properties. The ultra-high molecular wear-resistant pipeline inherits the excellent characteristics of ultra-high molecular weight polyethylene. So why does UHMWPE pipe have such good fluidity?



Here are a few factors that explain UHMWPE Pipe's excellent liquidity:

1. The pipe itself contains a waxy substance, the friction coefficient is only 1/6 of the new steel pipe, the flow resistance is small, and its internal diameter design can be reduced by 15.4% compared to the steel pipe.

2. The pipe itself is well lubricated, and its self-lubricating dynamic performance is better than oil-lubricated steel or brass. The surface will not cause thermal adhesion, especially in places with harsh environments, dust, and sand. This product's own dry lubrication The performance is more fully displayed, not only can move freely, but also protect the related workpiece from wear or strain.

3. The wear resistance and corrosion resistance of the pipe can keep the pipe wall smooth and unobstructed at all times, and the circulation capacity is more than 50% higher than that of the steel pipe, so that the transmission system can maintain a low-pressure smooth state for a long time.

4. It is not easy to scale. When the medium flow rate in the pipe reaches 2.3 meters per second, the pipe will not scale, which greatly reduces the cost of cleaning and avoids secondary pollution.

Because the UHMWPE pipe not only has good fluidity, but also has the advantages of wear resistance, impact resistance, self-lubrication, non-scaling, good resistance to environmental stress cracking, high resistance to internal pressure, and lightness, it replaces steel pipes and expensive alloys. Steel pipes and stainless steel pipes are used for the transportation of slurry-like solid-liquid mixtures in various industries, to solve the problems of pipeline wear, decay and scaling in the transportation process, such as coal, mining slurry transportation, coal water slurry transportation, and thermal power plant fly ash Transportation, river and lake dredging, municipal sewage sludge and sludge transportation, salt-making chemical slurry transportation, etc.
