80ft diameter API Std 650 austenitic stainless steel storage tanks
Structural shapes of 9% and 5% nickel steel may be furnished to the chemical and physical requirements of ASTM A353, A553, or A645. Physical tests shall be in accordance with the requirements of ASTM A6.API Std 650 austenitic stainless steel storage tanks used Piping, Tubing, and ForgingsMaterial used for piping, tubing, and forgings shall be compatible in welding strength, and thermal expansion coefficient with the tank shell material. In addition to the specific requirements of this appendix, all piping within the limitations of 1.3.2 shall fulfill the minimum requirements of ASME B31.3.
This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API Std 650 austenitic stainless steel storage tanks design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.
The API Std 650 austenitic stainless steel storage tanks must go through strict inspection before putting into use. Inspection of plate groove of API Std 650 austenitic stainless steel storage tanks, vertical oil tank: After finishing the groove processing of oil tank plate, it is necessary to conduct dye penetrant inspection on the groove. This process is mainly aimed at the hard damage of groove in the machining process and the defects of the plate itself. If any defect is found, it shall be processed again until the defect disappears.
