Vancouver — Vancouver-based Northwest Pipe Co. said Thursday it has acquired Permalok Corp., a fabricator of steel piping. Permalok’s patented interlocking pipe-joining system “complements and expands” Northwest Pipe’s product line, the company said in a news release, and strengthens the company’s water transmission business.

Northwest Pipe — which manufactures steel pipe primarily for drinking water systems — said the acquisition also opens opportunities to “expand in other segments such as structural pipe, industrial and the water transmission business.”

Permalok will continue to operate out of its St. Louis and Salt Lake City manufacturing locations, Northwest Pipe said.
