Quality Assurance

The final step before tie-ing in a pipe line assembly or pipe segment is the hydrostatic test. This critical test is usually done in a cramped trailer full of fittings and hoses. Midwestern Contractors wanted something better for their customers, operators and inspectors.

The project was meticulously designed and the piping runs totaled over 9,000' with most installed on racks and some underground. The purpose of the project was to install piping to carry butane from the storage field and into the refinery for processing and blending.

The Great Lakes hold 20% of the world’s fresh water and they stretch 1,600 miles from Duluth, Minnesota to the St. Lawrence Seaway. 

December in Northern Illinois & Indiana usually brings freezing weather and light snow. This year has been different. 

A recent project awarded to Midwestern Contractors (MWC), involved the removal of temporary Black Diamond repairs to three bends where external corrosion was discovered. 

During the 2014 construction season Midwestern Contractors (MWC) completed a large gas integrity project in Northern Illinois. This project included fabrication, piping modifications, launcher and receiver installations, valve installations and hydro-testing of line segments.
