What does ASME B31.3 address?

ASME B31.3 is specifically focused on the requirements for the design, materials, fabrication, assembly, and inspection of process piping used in various industries, notably the petrochemical sector. This code sets forth safety and performance criteria to ensure that piping systems can handle the specific demands of process industries, including considerations for pressure, temperature, and fluid properties.

The importance of this standard lies in its comprehensive approach to ensuring that piping systems are built and maintained to industry standards, which significantly contributes to the safety and reliability of operations in facilities that rely on such systems. By addressing not just the construction but also the maintenance and inspection nuances of process piping, ASME B31.3 plays a crucial role in minimizing risks associated with piping failures and ensuring compliance with regulatory requirements.

In contrast, the other options mention topics that are outside the scope of ASME B31.3, such as structural integrity assessments, electrical wiring, and non-destructive testing, which are governed by different standards and codes.
