Does your company fabricate or market boilers?  Do you need to have your boilers certified in accordance with the standards for Power Boilers from the American Society of Mechanical Engineers (ASME)?  Well then, an S-Stamp is for you. In this case, the S-stamp is for Power Boilers and applies to two types of boilers under Section I of the latest copy of the ASME Boiler and Pressure Vessel Code.   First, it applies to boilers in which steam or other vapor is produced at a pressure greater than 15 psig (100 kPa) external to itself.  Second, it applies to high temperature water boilers intended for use with operating pressures greater than 160 psig (1.1 MPa) and/or has temperatures exceeding 250 degrees F (120 degrees C).

Getting the S-stamp is not easy as there are many things a company needs before ASME will issue the stamp.  These “things” include but are not limited to:  A Quality Control (QC) System, initial investments and personnel to maintain.  These subjects are covered in more detail under  sections  PG-104 through 109, and PG-111 of Section I of the most recent revision of the ASME Boiler and Pressure Vessel Code.  These sections cover general information, types of stamps relative to Section I, applications, agreements, quality control systems required, and stamping of boilers and associated power piping as well as field-assembled boilers.   Once a company has satisfied the ASME requirements, it will receive the S-Stamp (and thus use it to stamp boilers) and a Certificate of Authorization from ASME to enable them to start code construction.  Additionally, although a company may have an S-stamp, it is also “good business practice” that the company has product liability insurance on the boiler prior to delivery.
