HSI has been an industry leader as a single source manufacturer of refractory lined vessels for many years now. Everyone, from our engineers to our welders, has the experience and knowledge necessary to deliver a superior product. We are fully compliant with ASME standards and maintain the ASME “U” stamp.
One of our largest competitive advantages is our ability to build and ship some of the largest completed vessels. We were one of the first to pioneer the Maximum Shop Assembly (MSA) technique. Using this method, we can ship completed vessels in one piece with finished internals ready for insulation.
Fired heaters have always been a specialty since we were founded, and they continue to be a primary service offering. Today, we maintain our reputation as the premier fired heater designer and manufacturer. As with all our vessels, we handle the entire process in-house, with no subcontractors.
