HDPE Pipe High Strength, Good Toughness
May 27, 2017

Application and Economic Evaluation of HDPE Pipe

Plastic pipe in the construction of the design theory and construction technology has made great development and improvement, and accumulated a wealth of practical experience, to promote the plastic pipe in the construction of water supply and drainage pipeline project occupies a very important position, and the formation of a The unstoppable trend of development. In China, the water pipe used in more plastic pipe mainly PVC-U water pipes, PP-R pipe, aluminum-plastic composite pipe (PAP), steel-plastic composite pipe (SP), HDPE pipe. HDPE pipe is the last two or three years before the emergence of the market, is the use of advanced production technology and technology, formed by hot extrusion, with corrosion resistance, smooth wall, small flow resistance, high strength, good toughness, light weight and so on.

HDPE pipeline is following the PVC-U water supply pipe, has become the world's second largest consumption of plastic pipe varieties.

First, HDPE water pipe development

At present, in the water supply and drainage pipeline system, the plastic pipe gradually replaced the cast iron pipe and galvanized steel pipe and other traditional pipe has become the mainstream use of pipe. Compared with the traditional pipe, plastic pipe has the advantages of light weight, corrosion resistance, low water flow resistance, energy saving, simple installation and low cost, and is favored by the pipeline engineering industry. At the same time, with the rapid development of the petrochemical industry, plastic manufacturing technology continues to progress, the rapid growth of plastic pipe production, product variety more diversified. Moreover, the plastic pipe in the building design theory and construction technology has made great development and improvement, and accumulated a wealth of practical experience, to promote the plastic pipe in the construction of water supply and drainage pipeline project occupies a very important position, and The formation of an irresistible development trend.

In China, the water pipe used in more plastic pipe mainly PVC-U water pipes, PP-R pipe, aluminum-plastic composite pipe (PAP), steel-plastic composite pipe (SP), HDPE pipe. HDPE pipe is the last two or three years before the emergence of the market, is the use of advanced production technology and technology, formed by hot extrusion, with corrosion resistance, smooth wall, small flow resistance, high strength, good toughness, light weight and so on.

HDPE pipeline is following the PVC-U water supply pipe, has become the world's second largest consumption of plastic pipe varieties. At present, the transmission of gas should be used PE80 and PE100 grade medium or high density polyethylene pipe; water pipe is usually PE80 and PE100 grade medium or high density polyethylene pipe, PE63 has gradually become out. In the water, the fastest growing PE100 pipeline system, the next five years is expected to reach more than 10% growth rate.
