The use characteristics of PPH pipeline: long service life, under rated temperature and pressure conditions, it can be used safely for more than long-term durability according to standards; corrosion resistance, PPH pipeline can withstand high-concentration acid and acid with a pH range of 1-14 in a wide range Alkali corrosion; heat-resistant heat preservation saves energy, small thermal conductivity, has good heat preservation performance; has reliable connection performance, the strength of the hot-melt joint is higher than that of the pipe body, and the seam will not be broken due to soil movement or load Open; good construction performance, PPH pipeline is light in weight, simple welding process, convenient construction, low overall project cost, and can adapt to complex process pipelines.
