Archiving and management of documentation for pressure vessels

Thread Content

Documentation: The production of pressure vessels must comply with **standards**, and the creation and archiving of completion documents must also adhere to **standards** just like product manufacturing. The quality of pressure vessel products is related to the safety of people’s lives and property; it is essential to carry out relevant work with rigor and responsibility. At the same time, in accordance with the regulations and technical standards for the management of pressure vessels, managing the completion documents and records is a fundamental task for enterprises. It is required that the preparation, review, and archiving of archival documents must be carried out in strict accordance with the requirements of the quality assurance manual. The quality assurance manual is a high-level directive document for the enterprise; it is prepared, drafted, and reviewed by quality assurance engineers, approved for issuance by the enterprise’s top management, and must be followed by all employees. The quality assurance system is applicable to the product documentation of pressure vessels manufactured by companies, as well as to the document control and archiving in various functional departments related to the system, such as the business department, technical department, production department, and quality supervision department. The control of archived documents and materials is carried out under centralized management by the Technical Quality Department in accordance with relevant regulations, while the manufacturing company assigns dedicated personnel for archived documents and materials to handle their specific control and management. Archived documents include quality records and forms, as well as external documents. The archived documents are prepared and reviewed by the responsible engineers. Except for the general and specific process specifications for pressure vessels, which are approved by the chief engineer, all other archived documents are approved by the quality assurance engineer. The product quality plan is prepared by the quality assurance engineer, reviewed by the relevant responsible engineers, and implemented and archived after approval. Changes: When there are changes in the company’s quality functions, when elements of the quality system and quality activities are added or removed, or when corporate policies conflict with newly issued regulations, the quality assurance engineer shall organize the timely revision of the Quality Assurance Manual. When a controlled document needs to be modified, the relevant personnel from the competent department shall fill out the \"Document Modification Approval Form\" and proceed with the approval process in accordance with the procedures applicable to the original document. After the document change is approved, fill out the \"Document Change Notification Form\" and attach the \"Revision Record Sheet\", then distribute it promptly within the original distribution scope. The original document shall be invalidated and filed among other archived documents. Modification and retrieval of documents: For document modifications, the department responsible for preparing them fills out a \"Document Change Record\", which is then approved by the original approver. The technical and inspection departments fill out the \"Document Change Notice\" in accordance with the requirements specified in the approved \"Document Change Record\", and proceed with the changes after obtaining approval from the quality assurance engineer. Changes to the record should be made by crossing out the original text, and the person making the changes shall sign and date it. All invalid or void documents and materials are withdrawn or collected by the records manager from all locations where they were issued or used, and stamped with a “Void” mark. For the documents and materials that need to be destroyed, the technical or inspection department submits a request for document destruction, and destruction is carried out after approval by the quality assurance engineer. All types of retained obsolete documents should be marked as “obsolete” or “retained” to prevent them from being confused with valid versions. The technical and inspection departments shall respectively prepare their own \"Controlled Documents Register\" and \"Record List\", and adjust them according to any updates to the documents. The retention period for documents and materials related to pressure vessels shall comply with relevant regulations. The specific contents of the archival documents prepared after equipment manufacturing are as follows: 1. Product drawings (1) Overall product diagram ； (2) The part diagram of this product. 2 Quality certification documents for pressure vessels at the time of leaving the factory (1) Table of contents of the quality certification documents for pressure vessels at the time of leaving the factory ； (2) Certificate of Supervision and Inspection for the Safety Performance of Boiler and Pressure Vessel Products ； (3) Product quality certificate for pressure vessels ； (4) Pressure vessel product certificate of conformity ； (5) Pressure vessel product data sheet ； (6) Quality inspection plan ； (7) List of materials used for the main pressure-bearing components of the product ； (8) Inspection report on the appearance and geometric dimensions of the pressure vessel ； (9) Weld radiographic inspection report ； (10) Weld radiographic inspection film evaluation form ； (11) Schematic diagram of the testing area ； (12) Penetrant testing report ； (13) Heat treatment inspection report ； (14) Hydraulic experiment report ； (15) Airtightness test report ； (16) Photocopy of nameplate ； (17) Pressure vessel material specification sheet ； (18) Certificate of safety and quality inspection for pressure vessel pressure-bearing components: (19) Product qualification certificate for end caps ； (20) Welded part quality certificate ； (21) Forge product certificate of conformity ； (22) Quality inspection report for forged product ； (23) Heat treatment inspection report for forged products ； (24) Experimental Report on Mechanical Properties of Forged Products ； (25) Quality certificate for continuous casting billets of forged products ； (26) Final layout diagram of the pressure vessel product. 3.
