HDPE(High Density Polyethylene) water supply pipes are used more widely, municipal engineering (HDPE) high density polyethylene pipes are suitable for the general use of pressure conveying water and drinking water that the temperature does not exceed *0 ℃, nominal pressure at 1.6MPa or less. There are municipal underground water supply, building to the (row) of water, irrigation, water projects and so on. In the water supply pipeline project, HDPE water pipes will eventually replace UPVC pipe. UHMW-PE’s full name is ultra-high molecular weight polyethylene pipe. It is the engineering thermoplastic that the average molecular weight greater than 2 million which is composed under the action of ethylene, butadiene monomer in the catalyst. This kind of material’s comprehensive performance is superior, it’s wear-resisting, low temperature resistance, corrosion resistance, lubrication itself and shock resistance are the highest among all of the plastic. The wear-resisting surpass PTEF, nylon and carbon steel etc. Its comprehensive performance can work in the condition of - **9 to *0℃ for a long time, wear-resisting, low temperature resistance is known as “amazing” engineering plastics. UHMW-PEengineering plastics pipe technology has matured gradually in China, more and more projects start to use this kind of wear-resistant material, and it becomes a new engineering thermoplastics with moderate price and excellent performance. It can be widely used in mining, mineral powder, pulp, tailings discharge pipeline), metallurgy, electric power, petroleum, textile, papermaking, food, chemical, mechanical, electrical and other industries.
