What document provides guidance on the design of welded leak boxes or clamps?

• A. API 577
• B. API 579
• C. ASME PCC-2
• D. ASME Section VIII, Div.2

Answer: (C)

The document that provides guidance on the design of welded leak boxes or clamps is ASME PCC-2. This standard, which is part of the American Society of Mechanical Engineers (ASME) guidelines, specifically addresses the requirements for repair and alteration of pressure equipment and piping. It includes detailed information on various types of clamps and leak boxes, including their design, installation, and testing methods. This makes it the appropriate reference for those designing such structures, ensuring that they comply with safety and integrity standards. In contrast, API 577 focuses on the welding processes and the metallurgical aspects related to welding, while API 579 deals with fitness-for-service evaluations of equipment, particularly addressing concerns like structural integrity. ASME Section VIII, Div. 2 covers the design and construction of pressure vessels but does not specifically address leak boxes or clamps in the detailed manner that ASME PCC-2 does. Thus, the focus of ASME PCC-2 on repair methods, including welded leak boxes, clearly establishes it as the correct guidance document for this topic.
