Imperial Industries, Incorporated can now also offer "Pressure Vessels". As of July 16, 2009 Imperial Industries, Inc. successfully completed the ASME Audit performed by members of ASME, the National Board and Hartford Steam Boiler. As a result of this audit, we have been issued a "U" stamp for fabrication of pressure vessels per ASME Section VIII, Division 1 and an "R" stamp for the repair and alteration of "Pressure Vessels" that are constructed per ASME Section VIII, Division 1. This allows us to fabricate tanks and vessels that are capable of holding pressures exceeding 15 PSI and up to 3,000 PSI internal pressure.
