Lined plastic ore concentrate conveying pipe introduction: Lined plastic ore concentrate conveying pipe is based on the requirements of different corrosion, the base pipe with inner and outer coating, through a special process to make plastic layer with a high temperature sintered steel outer wall. Lined plastic ore concentrate conveying pipe is mainly used in civil construction, municipal construction and other water pipe size diameter, drinking water pipelines, pharmaceutical, food and other industries conveying process piping food media. Lined plastic ore concentrate conveying pipe characteristics 1, has a good temperature resistance. Suitable water temperature is -30 ℃ ~ 80 ℃. 2, has a good chemical stability and water resistance. No rust, no fouling, no microbial growth, in line with the Ministry of Health "drinking water transmission and distribution equipment and safety evaluation criteria protective materials." 3, smooth wall, the flow is not reduced caliber, improve transport efficiency. 4, with good pressure resistance, not aging, embrittlement, especially those with a better performance in terms of resistance to thermal expansion and contraction. 5, demanding to adapt to the natural environment, can be laid directly buried use.
