Which of the following documents provides guidelines for the repairs of pressure piping?

• A. API RP 582
• B. NB-23
• C. ASME PCC-2
• D. ASME B31.8

Answer: (C)

The document that provides guidelines for the repairs of pressure piping is ASME PCC-2. This standard specifies the requirements for the repair and alteration of piping systems, including the conditions under which repairs can be made and the methodologies to be followed. It encompasses practices for various types of repairs, ensuring that safety and integrity are maintained in pressure piping systems.

ASME PCC-2 is essential for professionals in industries dealing with pressure piping, as it helps ensure compliance with safety standards and regulatory requirements, providing a framework for making acceptable repairs while preserving the operational reliability of the piping system.

Other documents mentioned have different focuses: API RP 582 relates to corrosion control in the refining industry, NB-23 outlines rules for the fabrication of pressure vessels, and ASME B31.8 covers gas transmission and distribution piping systems, which are not specifically oriented towards repair guidelines. Understanding these distinctions is crucial for selecting the appropriate standard for a given situation.
