Technical assurance measures for the quality of titanium-nickel pipeline materials:
1. Before the titanium-nickel pipe materials are put into storage, they must pass the self-inspection first, and then submit the self-inspection record, material certificate, quality assurance form, test report and other materials together with the inspection application to the owner and supervisor for inspection. Storage use.
2. Pipeline material requisition control method is implemented, that is, the requisitioner fills out the requisition form according to the drawing, and after the technical staff checks it, it is handed over to the warehouse clerk, and the custodian will issue the material according to the material list on the requisition list.
3. The warehousing pipeline shall be painted with color code in accordance with the marking regulations in time to prevent confusion and misuse. The warehousing valve shall be subjected to pressure test according to the regulations, and the unqualified valve shall be returned and replaced in time.
4. Set up a titanium-nickel pipeline prefabrication yard to increase the ground and pre-construction work to alleviate the adverse effects of tension in the later period. The construction machinery, materials, and prefabricated parts in the pipeline prefabrication plant shall be placed, listed, and marked in different categories. Organize special production for tube racks.
5. The delivery acceptance of materials shall be carried out in strict accordance with the requirements of the company's quality system procedures and documents. The use of materials without conformity certificates and material certificates is strictly prohibited.
6. Do a good job in material identification and weld location identification.
7. The management of pipeline materials will be dynamically managed through the use of computer network technology, and materials will be used in strict accordance with the drawings.
8. The bevel processing of the pipe is carried out by a cutting machine or a beveling machine. The bevel processing machine of the stainless steel pipe must be specially used to prevent "iron pollution" carburization.
9. Titanium-nickel pipeline installation shall be constructed in strict accordance with standards and specifications, and process discipline shall be observed. When valves with directional requirements are installed, the flow direction of the pipeline medium must be confirmed, and reverse installation is strictly prohibited. The installation of the pipe supports and hangers is carried out in strict accordance with the requirements of the design documents.
10. Each process must be inspected and recorded in accordance with the technical requirements, and provided to the supervision unit and the construction unit for random inspection at all times.
