1 | New type 80 storage containers have not been authorized since Dec. 31, 1947. |
2 | Container type may be increased by increments of 25. The minimum design pressure of containers must be 100% of the container type designations when constructed under 1949 or earlier editions of the 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. | |
