7)         Drawings and Specification Control – The drawings and specification control system shall provide procedures assuring that the latest applicable drawings, specifications and manufacturer's available instructions required are used for valve repair, inspection and testing.


A)        Specific reference shall be made to the materials used for the repair of the various valve parts (PG-73.2.3, Section I and UG-136(b)(3), Section VIII, Division 1 of the ASME Code).


B)        Mechanical requirements shall comply with the ASME Code.  See applicable Code Section.


8)         Material and Part Control – The material and part control section shall describe procurement of parts from the original valve manufacturer or their designated representative, if applicable, and of material with request for mill test certification as required.  It shall also describe receiving, storage and issuance, as well as the following:


A)        State the title of the individual responsible for the procurement of all material and parts.


B)        State the title of the individual responsible for certification and other records as required.


C)        All incoming material and parts shall be checked for conformance with the purchase order and, when applicable, the material specifications or drawings.  Indicate how the material or part is identified and how identity is maintained by the Quality Control System.


D)        All critical parts shall be fabricated by the valve manufacturer.  Critical parts are defined as any part that may affect the flow passage, capacity, pressure rating or valve function.


9)         Repair and Inspection Program – The repair and inspection program section shall include reference to a document (such as a report, traveler or checklist) that outlines the specific repair and inspection procedures to be used in the repair of safety and safety relief valves.  Provisions shall be made to retain this document for a period of at least five years as a part of quality control traceability documents.


A)        Each valve or group of valves shall be accompanied by the document referred to in subsection (b)(9) for processing through the plant.


B)        The document referred to in subsection (b)(9) shall include material check, reference to items such as the welding procedure specifications (WPS), fit-ups, NDE technique, heat treatment, and pressure test methods to be used.  There shall be a space for "sign-offs" at each operation to verify that each step has been properly performed for each valve.


C)        The system shall include a method of controlling the repair or replacement of critical valve parts.  The method of identifying each spring shall be indicated.


10)         Welding, NDE and Heat Treatment (when applicable) – When welded repairs are made by the Certificate holder, the Quality Control System Manual shall indicate the titles of the persons responsible for the development and approval of the welding procedure specifications and their qualifications, and the qualifications of welders and welding operators.
