Periodic Inspection Boilers and Pressure Vessels
The owner of a boiler or pressure vessel is required to have periodic inspections performed by a commissioned inspector to ensure that the boiler or pressure vessel meets the minimum code requirements and is safe to operate. A high-pressure boiler [in which steam is generated at a pressure of more than 15 P.S.I.] is required to be inspected each year including internal and external inspections. A steam heating boiler [in which steam is generated at less than 15 P.S.I.] or a hot water heating boiler [in which the operating pressure does not exceed 160 P.S.I. and/ or temperature does not exceed 250 degrees (F)] are required to be inspected every two years. Pressure vessels greater than 5 cubic feet and operating at a pressure greater than 125 P.S.I. are required to be inspected every three years.
