Analysis Of The Advantages Of Hdpe For Water Pipes.

- Jan 27, 2018-

A good pipeline should not only have good economic performance, but also have a series of advantages such as stable and reliable interface, anti-impact of material, anti-cracking, aging resistance and corrosion resistance. HDPE water pipe is a synthetic resin additive with additives made from melting and molding. Additives include plasticizers, stabilizers, fillers, lubricants, colorants, ultraviolet absorption agents, modifiers, etc. HDPE pipe is mainly used for: municipal engineering water supply systems, building indoor water supply system, outdoor buried water supply system and the residential area, plant area of buried water supply system, the old pipeline repair, plumbing and water treatment engineering, the botanical garden, irrigation and other areas of industrial pipes and so on. Compared with traditional pipe, wei star Hdpe water pipe has the following a series of advantages: 1. The connection is reliable, polyethylene pipe system using electric hot melt connection between, the strength of the joint is higher than the strength of pipe body. 2. Good low-temperature impact resistance: polyethylene of low temperature embrittlement temperature is extremely low, can be in 60-60 ℃ temperature range for safe use. During the winter construction, because of the good impact resistance of the material, the pipe will not crack. 3. Good anti-stress cracking: HDPE has low notch sensitivity, high shear strength and excellent resistance to scratch, and environmental stress cracking is also very prominent. 4. Good chemical resistance: the HDPE pipeline can withstand the corrosion of various chemical media, and the chemical substances present in the soil will not cause any degradation of the pipe. Polyethylene is an electrical insulator, so there will be no decay, rust or electrochemical corrosion; Nor does it promote the growth of algae, bacteria or fungi. 5. Aging resistance and long service life: a 2-2.5% uniform carbon black polyethylene pipe can be stored in open air for 50 years and will not be damaged by ultraviolet radiation.

In the field of mud conveying, HDPE is compared with steel pipe.

The pipeline has better wear resistance, which means the HDPE pipeline has longer service life and better economy.
