*ASME PCC-2 stands for the American Society of Mechanical Engineers (ASME) Post Construction Committee 2. It is a standard developed to provide guidelines and procedures for the repair of pressure equipment, including vessels, piping, and related components, after they have been constructed and put into service. ASME PCC-2 covers various aspects of repair, including design, fabrication, inspection, and testing, and it offers recommendations for both temporary and permanent repairs depending on the situation. The standard is widely used in industries where pressure equipment is prevalent, such as petrochemical, oil and gas, power generation, and manufacturing.
