A131 grade EH36 plates API Std 650 larger diameter tanks
According to the standard of head of API Std 650 larger diameter tanks, there should be no crack, delamination, inclusion and other defects on the groove surface, which is consistent with the steel plate standard. The API Std 650 larger diameter tanks head polishing can adopt different technology according to different requirements, including rough polishing, medium polishing and fine polishing. Only the materials used for the third type of pressure vessels must be retested, and the materials used for the first and second class pressure vessels are not generally re inspected.
Inspection of low-pressure storage tank Butt-weldsComplete penetration and complete fusion is required (to the degree mandated by the acceptance criteria for examination method utilized) for welds joining tank wall plates to API Std 650 larger diameter tanks tank wall plates. Examination for quality of welds shall be made using either the radiographic method specified in API 620 standard 7.15.1 and applied in 7.17, or alternatively, by agreement between the Purchaser and the Manufacturer, using the ultrasonic method specified in 7.15.3.1. In addition to the radiographic or ultrasonic examination, these welds shall also be visually examined as specified in 7.15.5. Furthermore, the Purchaser’s inspector may visually inspect all butt-welds for cracks, arc strikes, excessive undercuts, surface porosity, incomplete fusion, and other defects.
API 650 Tanks in which liquid fluids are stored and designed to withstand atmospheric pressure operation, less than 18 kPa, or internal pressures not exceeding the weight of the API Std 650 larger diameter tanks roof, with temperatures no higher than 93, 3 C are included in the scope of this design code.
