About United Piping, Inc.

Your trusted partner in pipeline construction

United Piping, Inc. (UPI) is a pipeline general contracting company located in Duluth, Minnesota. We provide new and existing facility construction, pipeline fabrication and other specialized services to the oil and gas pipeline industry.

Our location on Lake Superior offers us easy access to the Port of Duluth-Superior, one of the largest inland seaports in the world and the largest port on the Great Lakes. While our pipeline construction portfolio has primarily been built on projects throughout the Midcontinent Region, United Piping, Inc. is prepared to expand our reach at any time. We are large enough to handle contracts big and small and specialized enough that our upper level management is involved in all aspects of all jobs.

UPI began in February of 1997, out of our predecessor, Ogston’s Inc., which enjoyed 35 years in the business and helped build the strong reputation we uphold today. In February of 1997, UPI was formed and in May of 2000, we built our current pipeline Fabrication and Maintenance facility that tripled our shop’s capacity and further expanded our fabrication capabilities. In 2009, UPI became a subsidiary of APi Group. In just four short years, our company has grown tenfold. With over 1,000,000 safe man-hours in the last two years, we pride ourselves on providing quality work, on time and completed safely. We are a growing organization, constantly building to take on larger and more complex projects within the oil and gas pipeline industry. It is all that we do!
