ASME Construction Standards Boiler & Pressure Vessel
All boilers and pressure vessels, such as water heaters, are required to be manufactured, constructed and assembled in accordance with the appropriate ASME (American Society of Mechanical Engineers) standards in place at the time of manufacture. Increased emphasis on energy efficiency has resulted in increased interest in alternative fuel boilers. Building designers, mechanical engineers and heating contractors all need to be aware of the requirement for ASME listing and verify the construction specifications of any boilers or pressure vessels to avoid the problems and costs associated with removing or converting units that do not meet these standards.
