When scheduling and carrying out periodic inspections to “in service” storage tanks, the requirements indicated in Section 6 of the said standard must be considered. One of the most important sections of the API 653 standard is the one associated with inspection requirements. The main factors that must be taken into account during the tank integrity evaluation the ones associated with the stored product, the environmental conditions, materials, live loads, foundations, distortions of the existing tank, etc. When a physical modification to the tank is required, an assessment of the future integrity of the tank will be performed. It is important to be familiar with these regulations for an adequate evaluation of the tank. This normative defines the acceptance procedures and criteria to be considered in the failure analysis. The S cope of the API 653 Standard is limited to the following tank components: foundation, tank bottom, shell, structure, roof, and nozzles to the face of the first flange.įor the assessment of degradation during service, additional normative must be consulted, such as API 579-1 / ASME FFS-1 (Fitness for Service). Design Considerations for Reconstructed Tanks.The API 653 standard was developed to guide during the inspection, repair, alteration and dismantling works of storage tanks designed and manufactured under API 650 or API 12C.Ĭontents are divided into the following sections:
