性能：介质工作温度：-25℃–+70℃；
规格：DN25-DN300
介质工作压力：正压1.6Mpa
负压在常温下为75Kpa
耐腐蚀性：对非氧化性酸（如盐酸、稀硫酸、氢氟酸）、稀硝酸、碱和盐酸都有良好的耐蚀性，但不耐浓硝酸、浓硫酸和其他强氧化剂的腐蚀。对有机溶剂常温下一般耐蚀性良好。
Steel-Polythylene Plastic Compound Pipe
PEATURE :Medium working temperature range :- 25℃–+70℃
Size:DN25-DN300.Medium working pressure :plus pressurel 1.6Mpa minus pressure 75Kpa under normal temperature.
Anticorrosive character :the pipe is better corrosion-resisting to iroxidability acid (such as hydorochloric acid, thin sulphuic acid, hydrofluoric acid), thin nitric acid, soda andsaltsolution, but it can not resist the corrosions of concentrated nitric acid, cincentrater sulphurcia other storn oxidants. When used under normal temperature, it is better corrosion -resisting to orsolrent.
