Who We Are

Northwest Pipe Fittings is proud to serve the 7th largest city in North Dakota since 1968. Forbes has repeatedly ranked Mandan as a “Best Place for Small Business and Careers”. We are happy to be a part of that business community.

Mandan and its surrounding area is largely agriculture-based. At one time it had five grain elevators and a flour mill, even though these don’t remain today Mandan continues to support the agricultural industry. In recent years, Mandan has diversified its economy to include petroleum refining, software development, food processing and that is just to name a few. The weather is similar to the rest of the state, cold winters with warm to hot (and often humid) summers.
