ASME PCC-2:2006 pdf download Repair of Pressure Equipment and Piping
1 SCOPE
This Standard provides methods for repair of equipment and piping within the scope of ASME PressureTechnology Codes and Standards’ after it has beenplaced in service. These repair methods include relevantdesign, fabrication, examination, and testing practicesand may be temporary or permanent, depending on thecircumstances.
The methods provided in this Standard address therepair of components when repair is deemed necessarybased on appropriate inspection and flaw assessmentThese inspection and flaw evaluation methods are notcovered 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 outsideof the scope of this Standard.
ORGANIZATION
This Standard is divided into five Parts.(a) Part 1 covers the scope, organization, and intentand is applicable to all articles in this Standard. Tablel provides guidance for the applicability of repair meth-ods listed in this Standard.

(e) Part 5 covers examination and testing methodsand techniques.
3INTENT
31
This Standard provides technical information, procedures,and recommendations for repair methods thatwere determined by consensus to be recognized andgenerally accepted good engineering practice. Whereequipment repair is subject to jurisdictional regulationjurisdictional approvals may be required.
3.2
The words should, shall and may are used in the repairarticles of PCC-2 and they have the following intent:should: an action that is not mandatory. It indicates anaction that when performed, is generally considered tobe good practice;however, there are some circumstanceswhen the action is not appropriate or required, so theword should is used to provide flexibility for the article tocover a broad range of circumstancesIt is not mandatoryunless so specified by others in the application of thesearticles.
shall: an action that is mandatory. It indicates an actionthat is an essential element of the repair method thatcannot be eliminated.
may: indicates an action that is permitted, but notrequired.
3.3
For administrative requirements such as inspection,documentation, and quality control, the user is referredto an applicable post-construction code and to the jurisdictional requirements. In the absence of an applicablepost-construction code or jurisdictional requirementsthe owner of the pressure equipment or piping shouldestablish the administrative requirements.A post-construction code is one that provides requirements andguidance for inspection and/or repair of equipment
