ASME PCC-2-2022

ASME PCC-2 provides methods for repair of equipment, piping, pipelines and associated ancillary equipment 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 seal welding of leaking water systems; qualification of nonmetallic composite repair systems, and updates to Part 1 – Scope, Organization and Intent; Article 206 on Full Encirclement Steel Reinforcing Sleeves for Piping; Article 207 on Fillet Welded Patches With Reinforcing Plug Welds; Article 211 on Weld Buildup, Weld Overlay, and Clad Restoration; Article 401 on Nonmetallic Composite Repair Systems: High Risk Applications; Article 402 on Nonmetallic Composite Repair Systems: Low-Risk Applications; Article 501 on Pressure and Tightness Testing of Piping and Equipment; and Article 503 on Test Devices for Localized Pressure or Tightness Testing of Welded Repairs.
