Which of the following ASME codes is focused on process piping?

• A. ASME B31.1
• B. ASME B31.3
• C. ASME B16.1
• D. ASME B31.8

Answer: (B)

The ASME code that is focused on process piping is ASME B31.3. This code provides standards for the design, materials, fabrication, assembly, inspection, and testing of piping systems used in chemical facilities, refineries, and similar plants. It addresses piping that carries process fluids, including both liquids and gases, ensuring safety and efficiency in the handling of potentially hazardous and high-temperature materials.

ASME B31.3 is specifically tailored to manage the unique challenges of process piping, which can involve complex configurations, varying pressure and temperature conditions, and the need for stringent regulatory compliance. This is why it stands out among the ASME codes as the go-to guideline for professionals working with process piping systems.

In contrast, the other codes mentioned focus on different aspects of piping systems; for example, ASME B31.1 covers power piping, ASME B16.1 pertains to cast iron pipe flanges and fittings, and ASME B31.8 deals with gas transmission and distribution piping. Each code has its domain and application, but when it comes to process piping specifically, ASME B31.3 is the relevant standard.
