Description

Anti-freezing and corrosion-resistant PE pipe

Technical Field

The utility model relates to a PE tubular product technical field specifically is a corrosion-resistant PE tubular product prevents frostbite.

Background

PE, Polyethylene (english abbreviation of Polyethylene of insulated temperature resistance), generally, is applied to a PE pipe water supply pipeline at a temperature lower than 40 ℃, and cannot be used for a hot water delivery pipeline. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, the micro-thin section of the HDPE is semitransparent to a certain degree, the development of plastic pipelines in China is fast, and the quality of the plastic pipelines is continuously improved. Plastic pipe industries mainly including polyvinyl chloride (PVC-U) pipes, Polyethylene (PE) pipes, and polypropylene (PP-R) pipes have been primarily formed. Among them, Polyethylene (PE) pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas distribution, gas transmission pipes, electrical and telecommunication protective sleeves, industrial pipes, agricultural pipes, etc. due to their unique advantages. It is mainly applied to urban water supply, urban gas supply and farmland irrigation.

Some PE pipes in the current market have poor anti-freezing performance, corrosion resistance and tear resistance due to simple structures, and are difficult to meet the use requirements of people.

We have therefore proposed an antifreeze corrosion resistant PE pipe in order to solve the problems set out above.

SUMMERY OF THE UTILITY MODEL
