本检验规范涵盖压力容器和保护这些容器的泄压装置（PRD）的在役检验、维修、更改和重新评定活动。本检验规范适用于已投入使用的所有碳氢化合物和化学工艺容器；然而，它也可以应用于其他行业的工艺容器，由所有者和经营者自行决定。这包括:a）根据适用的建造规范[例如，ASME锅炉和压力容器规范（BPVC）]建造的容器； 如果压力容器已按照美国机械工程师协会（ASME）第八节规范建造，则API 510适用于第1和第2部分，而不是第3部分；b） 无建造规范建造的船舶（非代码船舶）；c） 根据特定设计、制造、检验、测试和安装的司法管辖区验收，建造并批准为司法管辖区专用船舶；d） 非标准船舶。然而，已正式退役的船舶（即从财务/会计角度来看不再是记录资产）不再包含在“- 服务检查”代码。被遗弃的就地船只可能仍需要进行一定程度的检查和/或风险缓解，以确保它们不会因持续恶化而成为危险。本规范仍涵盖暂时停止使用和保存以备将来使用的压力容器。ASME规范和其他公认的施工规范适用于新结构。尽管设计、焊接、无损检测（NDE）和材料的大部分技术要求都可以应用于- 工作压力容器，如果由于某种原因，已投入使用的项目因其新的结构方向而无法遵循施工规范，则设计、材料、制造和检验要求可遵循API 510而非施工规范。如果施工规范和API 510中的要求涵盖在用容器，或者如果两个规范之间存在冲突，则以API 510的要求为准。API 510不包括新制造的压力容器的源检验。 参考API RP 588《固定设备的来源检验和质量监督推荐规程》，以获取对制造和/或维修将在现场安装的压力容器的供应商供应商的监督指导。

This inspection code covers the in-service inspection, repair, alteration, and rerating activities for pressure vessels and the pressure-relieving devices (PRDs) protecting these vessels. This inspection code applies to all hydrocarbon and chemical process vessels that have been placed in service; however, it could also be applied to process vessels in other industries at owner-operator discretion. This includes:a) vessels constructed in accordance with an applicable construction code [e.g., ASME Boiler and Pressure Vessel Code (BPVC)]; where a pressure vessel has been constructed to the American Society of Mechanical Engineers (ASME) Section VIII Code, API 510 is intended to apply to Divisions 1 and 2 and not Division 3;b) vessels constructed without a construction code (noncode vessels);c) vessels constructed and approved as jurisdictional special based upon jurisdiction acceptance of particular design, fabrication, inspection, testing, and installation;d) nonstandard vessels.However, vessels that have been officially decommissioned (i.e. no longer are an asset of record from a financial/accounting standpoint) are no longer covered by this “in-service inspection” code. Abandoned-in-place vessels may still need some amount of inspection and/or risk mitigation to assure they do not become a hazard because of continuing deterioration. Pressure vessels temporarily out of service and preserved for potential future use are still covered by this code.The ASME Code and other recognized construction codes are written for new construction. Although most of the technical requirements for design, welding, nondestructive examination (NDE), and materials can be applied to the inspection, rerating, repair, and alteration of in-service pressure vessels, if for some reason an item that has been placed in service cannot follow the construction code because of its new construction orientation, API 510 rather than the construction code can be followed for the requirements for design, material, fabrication, and inspection. If in-service vessels are covered by requirements in the construction code and API 510 or if there is a conflict between the two codes, the requirements of API 510 take precedence.API 510 does not cover source inspection of newly fabricated pressure vessels. Refer to API RP 588, Recommended Practice for Source Inspection and Quality Surveillance of Fixed Equipment, for guidance on the surveillance of supplier vendors fabricating and/or repairing pressure vessels that will be installed on site.
