VANCOUVER, WA--(Marketwire - February 2, 2011) - Northwest Pipe Company (NASDAQ: NWPX), an industry leader of engineered welded steel pipe and tube products, has plans to expand its Atchison, Kansas mill facility. The Atchison location is home to one of three Tubular Products Group locations. The facility currently operates two pipe mills with a product range of 3.5 inches to 16 inches outside diameter and wall thickness up to 0.281 inches. The expansion, anticipated to be complete by the fourth quarter of 2011 will increase the production capacity by more than 50 percent, improve productivity and enable the Group to produce product up to 0.375 inch wall.

"The project is consistent with our view that there are very attractive opportunities in our Tubular Products segment," added Bob Mahoney, President of Northwest Pipe Company's Tubular Products Group.
