Final answer:
An Authorized Inspector or Quality Control personnel ensures conformity of piping systems to the ASME B31.3 Code and the engineering design, overseeing examinations and testing necessary for verifying piping integrity and safety.
Step-by-step explanation:
The individual who is responsible for verifying that all required examinations and testing have been completed, and inspecting piping to ensure conformation to applicable examination requirements of the ASME B31.3 Code and the engineering design, is often referred to as the Authorized Inspector or Quality Control personnel within an organization. This role is crucial because it involves ensuring that the piping systems meet the rigorous standards for safety and functionality set by the American Society of Mechanical Engineers (ASME). The Authorized Inspector must be well-versed with the ASME B31.3 Code, which details the requirements for process piping and is a subsidiary code of the ASME Boiler and Pressure Vessel Code (BPVC). They must have a thorough understanding of not only the code but also the engineering design requirements to confirm that all examinations, including nondestructive examinations, are conducted and that the pressure systems are constructed safely and efficiently.
