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.
