Which ASME code covers power boilers?

The correct answer highlights the specific focus of ASME Section I, which is dedicated to the construction of power boilers. This section provides guidelines for the design, fabrication, inspection, testing, and certification of power boilers that operate at high pressures and temperatures. The standards outlined in Section I ensure that power boilers function safely and efficiently, while minimizing the risk of catastrophic failures.

Section II does not cover power boilers specifically; instead, it addresses material specifications necessary for the construction of various pressure-retaining components, providing the requirements for materials and their safe use in pressure equipment. Section III pertains to nuclear facility components and is not relevant to power boilers. Section IV speaks to heating boilers, which generally operate at lower pressures than those covered in Section I, thereby distinguishing it further from the high-pressure context that Section I encompasses.
