ASTM A36 plates API standard 650 aboveground steel oil storage tanks

As we know, the vertical metal tank, API standard 650 aboveground steel oil storage tanks is welded by many components, and the welding quality of each component determines the later use effect of the API standard 650 aboveground steel oil storage tanks. Professional API standard 650 aboveground steel oil storage tanks manufacturers should have a set of professional skills in the welding process of API standard 650 aboveground steel oil storage tanks. Key points for weld inspection of vertical metal tank, API standard 650 aboveground steel oil storage tanks:
1. It is strictly forbidden to paint the welds before passing the inspection.
2. Visual inspection shall be carried out for welds.
3. NDT shall be carried out on the weld.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 standard 650 aboveground steel oil storage 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 petroleum storage tanks are used for API standard 650 aboveground steel oil storage tanks storage. API 650 petroleum storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature). Welding API standard 650 aboveground steel oil storage tanks certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For API 650 petroleum storage tanks, non-destructive inspections are required, but third-party inspections are not required.Our company has a comfortable office environment, covers a large area, can accommodate hundreds of people working at the same time.
