MTSCO have continued to make breakthroughs in the field of chemical injection line. We mainly supply materials of stainless steel, duplex steel and nickel alloy (such as 304/L,316/L, 2205, 2507,alloy 625, alloy 825). Diameters from 4mm to 25mm.
MTSCO chemical injection line has good corrosion resistance, fatigue resistance and weldability. It has been successfully used in certain harsh subsea and downhole conditions, used as chemical injection line, downhole tools, geothermal coiled tubing and so on. We can supply various kinds of plastic materials to make single core or multi-core coiled tubing according to customer needs.
