本规范涵盖了油气分离器和油气水分离器的设计、制造和工厂测试的最低要求。油气分离器和油气水分离器用于油气生产，位于井口和管道之间的生产流水线上的某个点。本规范涵盖的分离器可为立式、球形或单管或双管卧式。除非买方和制造商另有约定，否则本规范的管辖权终止于ASME锅炉及压力容器规范第七节第1部分中规定的压力容器。本规范涵盖的压力容器通常被归类为自然资源容器。本规范范围外的分离器包括离心分离器、过滤分离器和除砂分离器。

This specification covers minimum requirements for the design, fabrication, and plant testing of oil and gas separators and oil-gas-water separators that are used in the production of oil and gas, and are located at some point on the producing flow line between the wellhead and pipeline. Separators covered by this specification may be vertical, spherical, or single or double barrel horizontal.Unless otherwise agreed upon between the purchaser and the manufacturer, the jurisdiction of this specification terminates with the pressure vessel as defined in Section VII, Division 1 of the ASME Boiler and Pressure Vessel Code. Pressure vessels covered by this specification are normally classified as natural resource vessels. Separators outside the scope of this specification include centrifugal separators, filter separators and desanding separators.
