TMK IPSCO, the American division of Russia’s TMK, was formed in June 2008 when TMK purchased ten pipe-manufacturing facilities from SSAB, a Swedish steel company that had acquired Chicago-based IPSCO a year earlier in 2007. Previously, Interprovincial Steel and Pipe Corp, IPSCO’s origins can be traced back to 1956 when its predecessor, Prairie Pipe Manufacturing Co., was established in Regina, Saskatchewan to meet western Canadian demand for welded line pipe.

Much of TMK IPSCO’s current production capacity comes from IPSCO’s 2006 acquisition of Newport, Kentucky-based NS Group Inc., a producer of seamless and welded pipe. This acquisition brought together core steelmaking and seamless pipe manufacturing operations in Koppel and Ambridge, Pennsylvania; welded pipe manufacturing and finishing operations in Wilder, Kentucky, Catoosa, Oklahoma, and Baytown, Texas; as well as Ultra Premium Oilfield Services, an Odessa, Texas-based producer of premium connections.

Today, TMK IPSCO comprises 12 manufacturing facilities in the U.S. and Canada. Welded and seamless pipe produced by the company is used in a variety of complex oil and gas drilling environments, from the Marcellus Shale in Pennsylvania and Ohio to the Eagle Ford Shale in Texas to the petroleum-producing regions of western Canada to challenging offshore projects in the Gulf of Mexico.
