本规程补充SAPI 650《储油用焊接钢储罐》。本规程和API 650共同规定了常压储罐的施工要求。本规程andAPI 650描述了地上非冷藏储罐的材料、设计、制造、安装、检查和测试的最低施工要求。本规程描述了对API 650的添加和修改。此外，本规程描述了关于API 650提供的选项的决策。本规程补充但不取代API 650和任何适用的司法管辖要求。本规程适用于设计内部压力为17.2 kPa（2.5 psig）或更低（见API 650，附录F）且设计温度低于260°C（500°F）的储罐（见API 650，附录M）。本规程假定使用API 650数据表来涵盖inAPI 650的要求，数据表作为补充来定义本规程的附加要求。

This Practice supplementsAPI 650, Welded Steel Tanks for Oil Storage. Together, this Practice andAPI 650provide requirements for the construction of atmospheric storage tanks.This Practice andAPI 650describe minimum construction requirements for the materials, design, fabrication, erection, examination, and testing of aboveground, non-refrigerated storage tanks. This Practice describes additions and modifications made toAPI 650. In addition, this Practice describes decisions made regarding options offered byAPI 650. This Practice supplements, but does not supersede,API 650and any applicable jurisdictional requirements.This Practice covers storage tanks that have design internal pressures of 17.2 kPa (2.5 psig) or less (seeAPI 650, Annex F) and design temperatures less than 260°C (500°F) (seeAPI 650, Annex M).This Practice presumes the use of theAPI 650Data Sheet to cover the requirements inAPI 650, and the Data Sheet, as a supplement, to define the additional requirements of this Practice.
