What ASME code symbol indicates a high pressure power boiler?

The ASME code symbol that indicates a high pressure power boiler is associated with the letter "S". This symbol is part of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, which establishes standards for the design, manufacture, and inspection of boilers and pressure vessels.

In the context of boiler designations, the "S" symbol signifies that the boiler is designed and intended for high pressure service, ensuring that it meets the stringent requirements for safety and efficiency in its operation. This designation is critical for maintaining safety standards and ensuring that the equipment is suitable for handling the pressures involved in power generation processes.

Understanding these symbols is important for professionals in the field as they indicate compliance with safety and operational standards critical for high pressure systems.
