Learn how heating boilers unintentionally cross into ASME Section I power boiler classification, what inspectors look for, and how to avoid costly compliance surprises.
ASME Section I of the Boiler and Pressure Vessel Code (BPVC) governs the design, construction, and certification of power boilers—the heavy hitters used to generate steam or high‑temperature water for power generation, industrial processes, and large facilities. This section exists for one reason above all others: safety through standardization.
An S-Stamp is a certification mark issued by the National Board of Boiler and Pressure Vessel Inspectors (NBBPVI). It signifies that a manufacturer is authorized to build and stamp power boilers, which are pressure vessels designed to generate steam for various applications, such as power generation, heating, and industrial processes.
