范围1.1本标准实施规程涵盖了150、300和600级耐蚀合金闸阀、截止阀、角阀和止回阀，其法兰端和对焊端由承压零件制成，包括符合ASME B16.34.1.2的材料。本标准实施规程涵盖了ASME B16.34中未涵盖的耐腐蚀阀门的附加施工要求。此类阀门由耐腐蚀合金制成，其性能特别适合其所处的环境。化学工艺和低温流体服务构成了两种应用。

1. SCOPE1.1 This Standard Practice covers Classes 150, 300 and 600 corrosion resistant alloy gate, globe, angle and check valves with flanged and butt weld ends which are constructed of pressure containing parts, including materials that conform to ASME B16.34.1.2 This Standard Practice covers additional construction requirements for corrosion resistant valves not covered by ASME B16.34. Such valves are made from corrosion resistant alloys whose properties are uniquely suited to the service into which they are placed. Chemical process and cryogenic fluid service constitute two such applications.
