API 653-2025  储罐检查、修理、改造和重建 下载

请注意：作为负责编制本出版物的API委员会的一项要求，部分附录可能无法以独立文件的形式提供，它们只是被简单地纳入基础出版物中。
请注意，本标准的翻译版本中可能不包含任何增补或勘误。
本标准涵盖按照API 650-2025（API 650-2020 中文版）及其前身API 12C建造的钢制储罐。它规定了此类储罐投入使用后保持完整性的最低要求，并涉及检查、维修、改造、搬迁和重建。
范围仅限于储罐基础、底部、壳体、结构、顶板、附属附件以及至第一个法兰面、第一个螺纹接头或第一个焊接端接头的喷嘴。API 650的许多设计、焊接、检验和材料要求均可应用于在役储罐的维护检查、评级、修理和改造。若本标准的要求与API 650-2025或其前身API 12C的要求存在明显冲突，则对于已投入使用的储罐，应以本标准为准。
本标准采用了API 650的原则；然而，储罐业主/运营商可根据具体的施工和操作细节，将本标准应用于任何按照储罐规范建造的钢制储罐。
本标准旨在供那些拥有或能够接触到在储罐设计、制造、维修、施工和检验方面经过技术培训且经验丰富的工程和检验人员的组织使用。
本标准不包含涵盖现有储罐中可能出现的所有不同情况的规则或指南。当设计和施工细节未给出，且在竣工标准中也无法找到时，必须采用与现行API 650标准所提供完整性水平相当的细节。
本标准认可了用于评估承压部件在役退化的适用性评估概念。API 579-1-2025/ASME FFS-1《适用性》为本标准中引用的特定退化类型提供了详细的评估程序或验收标准。当本标准未针对特定退化类型提供具体的评估程序或验收标准，或当本标准明确允许使用适用性标准时，可使用API 579-1/ ASME FFS-1来评估本标准中涉及的各种退化类型或测试要求。

API 653-2025 Tank Inspection, Repair, Alteration, and Reconstruction

Full Description
Please note: as a requirement of the API committee that develops this publication, some addendums may not be available as standalone files, they are simply incorporated into the base publication.

Please note that any addenda or errata may not be included in translated editions of this standard.

This standard covers steel storage tanks built to API 650 and its predecessor API 12C. It provides minimum requirements for maintaining the integrity of such tanks after they have been placed in service and addresses inspection, repair, alteration, relocation, and reconstruction.

The scope is limited to the tank foundation, bottom, shell, structure, roof, attached appurtenances, and nozzles to the face of the first flange, first threaded joint, or first welding-end connection. Many of the design, welding, examination, and material requirements of API 650 can be applied in the maintenance inspection, rating, repair, and alteration of in-service tanks. In the case of apparent conflicts between the requirements of this standard and API 650-2025 or its predecessor API 12C, this standard shall govern for tanks that have been placed in service.

This standard employs the principles of API 650; however, storage tank owner/operators, based on consideration of specific construction and operating details, may apply this standard to any steel tank constructed in accordance with a tank specification.

This standard is intended for use by organizations that maintain or have access to engineering and inspection personnel technically trained and experienced in tank design, fabrication, repair, construction, and inspection.

This standard does not contain rules or guidelines to cover all the varied conditions which may occur in an existing tank. When design and construction details are not given, and are not available in the as-built standard, details that will provide a level of integrity equal to the level provided by the current edition of API 650 must be used.

This standard recognizes fitness-for-service assessment concepts for evaluating in-service degradation of pressure containing components. API 579-1/ASME FFS-1, Fitness-For-Service, provides detailed assessment procedures or acceptance criteria for specific types of degradation referenced in this standard. When this standard does not provide specific evaluation procedures or acceptance criteria for a specific type of degradation or when this standard explicitly allows the use of fitness-for-service criteria, API 579-1-2025/ASME FFS-1 may be used to evaluate the various types of degradation or test requirements addressed in this standard.
