What code regulates the rules for construction of Power Boilers?

The correct answer is ASME Section I, as it specifically addresses the rules and guidelines for the construction of power boilers. ASME stands for the American Society of Mechanical Engineers, and Section I is dedicated to the design, fabrication, and inspection standards for power boilers. This code sets the foundation for ensuring that boilers operate safely under pressure and are constructed with materials that can withstand the high temperatures and pressures involved in power generation.

This section is critical for engineers and professionals in the power industry, as it outlines specifications that must be met to achieve safe and reliable boiler operations. Compliance with ASME Section I helps in minimizing the risks associated with boiler failures, which can have severe consequences.

The other choices refer to different codes or standards. For example, CSA B51 oversees the construction and maintenance of boilers and pressure vessels in Canada, but it does not directly pertain to the power boiler construction guidelines outlined in ASME Section I. ANSI B16.5 is related to pipe flanges and fittings but does not address boilers specifically. ASHA Code 32 focuses on safety and health regulations but is not specific to power boiler construction. Thus, ASME Section I is the most relevant and appropriate choice for this question.
