Vancouver, Washington-based welded steel pipe and tube products manufacturer Northwest Pipe Company announced Tuesday that its Bossier City facility, which manufactures Electric Resistance Welded (ERW) steel pipe for the company's Tubular products group, can begin production of carbon grade casing (OCTG casing) and line pipe due to a recently completed American Petroleum Institute (API) audit for 5L and 5CT.
Bob Mahoney, President of Northwest Pipe Company's Tubular Products Groups commented that "our API certification will position this facility to produce both OCTG casing products and line pipe. It is part of our continuing Tubular Products strategy to grow our energy products offerings."
