What is Chemical Injection Line?
Coiled tubes for chemical injection line usually made of stainless steel, duplex stainless steel or nickel alloys, including stainless steel 316L, duplex 2205 and 2507, Nickel alloy 825 and alloy 625. The coiled tubes can be welded & redrawn tubes or seamless cold drawn tubes. Control lines are has very long continuous lengths coil, coiled tubing usually packed on coil wound on wooden drum or spool, also specific metal reels, Encapsulated and PVC coated are available.

MTSCO has been supplying control line to the heat exchanger/ oil and gas industry for more than a decade. In recent years, we have continued to make breakthroughs in the field of coiled tubing, downhole control lines, and chemical injection control lines. Our control line has been successfully used in kinds of heat exchanger, certain harsh subsea and downhole conditions, and through continuous research and development, is able to meet the stringent quality requirements of oil field and other industries.
