Which code contains Rules For Construction of Power Boilers?

The code that contains the Rules for Construction of Power Boilers is indeed ASME Section I. This section of the ASME Boiler and Pressure Vessel Code specifically addresses the design, fabrication, installation, and inspection requirements for power boilers to ensure their safe operation. It provides detailed guidelines that help engineers and manufacturers create boiler systems that can withstand the stresses and operational demands they will face in service.

ASME Section I is often used in industries where steam generation is critical, such as power plants, and it ensures that the boilers are constructed to high standards of safety and efficiency. This code is pivotal in establishing the baseline for the construction of these systems, allowing for uniformity and reliability across different types of power boilers.

In contrast, the other options focus on different aspects or types of boilers and pressure vessels. For example, CSA B51 pertains to the design and construction of boilers, pressure vessels, and pressure piping, but it is not specifically dedicated solely to power boilers like ASME Section I. ASME Section VIII covers the design criteria for pressure vessels but does not specifically include rules for power boilers. CSA B52 deals with mechanical refrigeration systems, which is unrelated to boiler construction.
