Complete Retube

Customers rely on Rasmussen Mechanical Services to perform maintenance tasks during planned plant outages. For the GPRE Superior project, it included removing 494 boiler tubes that were nearly 30 ft long. To increase the boiler's efficiency, rifled (XID) boiler tubes were installed mechanically and then welded to ensure a proper seal. The boiler was hydrostatically tested and witnessed by an Authorized Inspector. The boiler was then boiled out, tuned for optimal efficiency, and brought back online with our Burner Services Division. Shoutout to our Sioux City Boiler Repair for the great work!
