How to ensure the construction quality of oil tank

The engineering quality of oil tanks not only affects production and operation, but also affects the life safety of workers. The factors that affect the construction quality, any link, any part of the problem will affect the whole project, so the quality management is more and more valued by people. How to guarantee the construction quality of oil tank?

1. Make preparations for the construction technology carefully, understand the design intent, master the construction acceptance specifications, and explain the construction technology to the construction team in detail.

2. Persist in the construction according to the design drawings, the acceptance specifications and the construction plan. If the design needs to be modified during the construction, it must be approved by the original design unit or the representative of Party A and the relevant personnel of the supervision unit, and a written visa procedure must be completed in advance.

3. The equipment and main materials used in the project must have a certificate of conformity and quality assurance. If material substitution is required, it must be approved by the original design unit or Party A's representative and relevant personnel of the supervision unit, and the material substitution procedures must be completed in advance.

4. Welders who participate in the construction of the project must pass the examination and perform welding within the valid period of the qualified project. Special operators such as on-site maintenance electricians, cranes, and shelf workers must hold job certificates.

5. All oil pipelines need to use arc welding for bottoming and electric welding to cover the surface to ensure welding quality.

6. Oil tanks and process pipelines must be tested for non-destructive flaws in accordance with the flaw detection ratios and methods required by the design and acceptance specifications. The flaw detectors must be certified.

7. After the oil tank is made, the air tightness test and water filling test are carried out according to the design requirements. The pipeline must be subjected to a pressure test to achieve full compliance with the acceptance technical specifications.

8. Improve the quality assurance system, adhere to the principle of who is responsible for the quality of the project, carry out regular quality inspections, and immediately rectify problems when they are found.

9. Fill in the installation technical records in time to ensure the synchronization, integrity and reliability of the technical data.
