The raw material of the PPH tube contains only carbon and hydrogen elements, and no other harmful or toxic elements exist, so it is more hygienic and reliable. The special material of this kind of pipe, high-performance polyethylene pipe, has developed rapidly in recent years, which has obviously enhanced its advantages in use and expanded its use scale; the appearance of the supplied material should meet the following requirements: the end surface is perpendicular to the axis of the pipe; the pipe fittings are complete , No defects, no deformation; the inner and outer walls of the pipes and pipe fittings are smooth and flat, without bubbles, cracks, peeling, and obvious marks and depressions, and the color is basically the same.
PPH duct has good analytical chemistry credibility, it can be corroded by sulfuric acid and concentrated sulfuric acid, and it is stable to various chemicals. The low content of aliphatic hydrocarbons, aliphatic hydrocarbons and isopropyl titanate hydrocarbons will loosen and dissolve polypropylene. As the crystal size increases, its analytical chemistry credibility also increases. Polypropylene is suitable for the manufacture of various chemical pipelines and parts, and the expected anti-corrosion effect is high-quality. General plastic pipes have the advantages of light weight, corrosion resistance, and non-scaling. PPH pipes also have the characteristics of non-toxic and hygienic.
