WAC 296-307-44003. Design and classification of storage containers

Storage containers must be designed and classified according to the following table: Minimum design pressure of container lb. per sp. in. gauge Container type For gases with vapor press. Not to exceed lb. per sp. in. gauge 100°F (37.8°C.) 1949 and earlier editions of ASME Code (Par. U-68, U-69) 1949 edition of ASME Code (Par.U-200, U-201); 1950, 1952, 1956, 1959, 1962, 1965, and 1968 (Division I) editions of ASME Code; All editions of API-ASME Code 2 200 1 215 200 250 Minimum design pressure of container lb. per sp. in. gauge Container type For gases with vapor press. Not to exceed lb. per sp. in. gauge 100°F (37.8°C.) 1949 and earlier editions of ASME Code (Par. U-68, U-69) 1949 edition of ASME Code (Par.U-200, U-201); 1950, 1952, 1956, 1959, 1962, 1965, and 1968 (Division I) editions of ASME Code; All editions of API-ASME Code 2 200 1 215 200 250 1 Container type may be increased by increments of 25. The minimum design pressure of containers must be 100% of the container type designation when constructed under 1949 or earlier editions of ASME Code (Par. U-68 and U-69). The minimum design pressure of containers must be 125% of the container type designation when constructed under: 1. The 1949 ASME Code (Par. U-200 and U-201), 2. 1950, 1952, 1956, 1959, 1962, 1965, and 1968 (Division I) editions of the ASME Code, and 3. All editions of the API-ASME Code. 2 Construction of containers under the API-ASME Code is not authorized after July 1, 1961. 1 Container type may be increased by increments of 25.
