The ASME Code recommends that safety valves should be adjusted by which personnel?

The American Society of Mechanical Engineers (ASME) Code emphasizes the importance of safety valves in ensuring the safe operation of boilers and pressure vessels. Safety valves are critical devices designed to open automatically to relieve pressure when it exceeds a predetermined limit, thereby preventing potential accidents or equipment failure.

The adjustment of safety valves is a task that requires specialized knowledge and expertise to ensure they function correctly and in accordance with safety standards. Manufacturers or their authorized representatives are the best-qualified personnel for this task because they have the specific training and detailed understanding of the design and operational requirements of their safety valves. They are familiar with the manufacturer’s specifications and can ensure that adjustments are made accurately, maintaining compliance with ASME standards.

Personnel like certified boiler operators, maintenance engineers, or third-party inspectors may have substantial knowledge about boiler operations and maintenance, but they do not possess the in-depth understanding of specific safety valve specifications that the manufacturer’s representatives do. Therefore, having the manufacturers or their authorized representatives adjust the safety valves ensures proper calibration and compliance with safety regulations, which is vital for reliable and safe operation.
