Welded Tube is the largest independent OCTG producer in Canada. The company began producing OCTG products with proprietary specifications for limited service applications in the Appalachian region in the USA, back in 1981. From these modest beginnings, Welded Tube has grown to become one of North America’s most trusted suppliers of Oil Country Tubular Goods.
Welded Tube maintains an unmatched reputation for product quality, innovation and customer service. Our facilities are strategically located in close proximity to both our supply base, as well as truck and rail access designed to service key energy markets across North America.
Welded Tube was the first ERW tube producer in North America registered to the now widespread, ISO 9001 Quality Management System. Today, Welded Tube-Concord’s current business management system is registered to ISO 9001:2008.
