ASME PCC-2 provides methods for repair of equipment and piping within the scope of ASME Pressure Technology Codes and Standards after it has been placed in service. These repair methods include relevant design, fabrication, examination, and testing practices and may be temporary or permanent, depending on the circumstances. The methods provided in this Standard address the repair of components when repair is deemed necessary based on appropriate inspection and flaw assessment. These inspection and flaw evaluation methods are not covered in this document, but are covered in other post-construction codes and standards. Only technical procedures and information are provided, administrative or policy requirements are outside of the scope of this Standard. Key changes to this revision include new supplemental articles on welded lip seals, welded hot taps, crimping of metallic pipe, test devices for localized pressure or tightness testing of welded repairs, and updates to Part 1 â?? Scope, Organization and Intent, Article 2.3 on Seal-Welded Threaded Connections and Seal Weld Repairs, Article 2.6 on Full Encirclement Steel Reinforcing Sleeves for Piping, Article 4.1 on Nonmetallic Composite Repair Systems: High Risk Applications, Article 4.2 on Nonmetallic Composite Repair Systems: Low-Risk Applications, and Article 5.1 on Examination and Testing.
