Which body sets the visual examination standards that are followed for steam or heating media piping welds?

The American Society of Mechanical Engineers (ASME) establishes the visual examination standards for steam or heating media piping welds. ASME is widely recognized for developing codes and standards related to the design and manufacturing of mechanical devices and systems, including piping. Their standards ensure that welding practices meet safety and quality requirements, thus protecting the integrity of the piping systems. Visual examination is a critical aspect of weld inspection, and the guidelines provided by ASME help ensure that welds are made correctly, free from defects, and appropriate for high-pressure applications. This is essential in maintaining safety and operational efficiency in industrial piping systems.
