Tenaris Ambridge, formerly IPSCO Koppel Tubulars, is a seamless steel tubing plant at 2225 Duss Avenue in Ambridge, Beaver County, Pennsylvania. Billets are heated in a gas-fired rotary furnace and processed into seamless tube. Tenaris S.A. acquired the plant from TMK in January 2020.
Overview
Operations at the plant involve the production of seamless steel tubing from steel billets, which are heated in a gas fired rotary furnace and then sent to the piercer mill. Finishing operations may include heat treating, straightening, end expansion and treatment with corrosion prevention coatings.
