When referring to the installation of a high-pressure boiler in Massachusetts, which ASME code section should be consulted?

The correct choice is B31.1 because it specifically addresses the requirements related to the construction and installation of power piping, which includes high-pressure boilers. This section of the ASME (American Society of Mechanical Engineers) code is crucial for ensuring safe and reliable operation of systems that generate steam or use high-pressure application methods.

B31.1 covers various aspects such as material selection, design criteria, fabrication, inspection, and testing of piping systems associated with power plants, which is directly relevant for high-pressure boiler installations. Therefore, consulting this code is essential for any pipefitter or engineer involved in the design and installation of power piping systems, ensuring compliance with safety standards and legal requirements in Massachusetts.

The other options refer to different areas of piping codes: B31.2 focuses on gas transmission and distribution piping systems, B31.5 deals with refrigerant piping, and B31.8 covers gas transmission and distribution. Each of these is tailored for specific applications that don’t directly relate to high-pressure boilers.
