36m diameter API standard 650 insulated tanks
Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API standard 650 insulated tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.
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 insulated 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.
The water dissolved in the oil will be separated out from the oil stored in the API standard 650 insulated tanks for a long time, and the acidic water layer will appear at the bottom of the API standard 650 insulated tanks for a long time, which will accelerate the corrosion of the API standard 650 insulated tanks and cause the wall thinning and even leakage. With the increase of service life, the API standard 650 insulated tanks must be inspected and cleaned regularly to check the hidden danger.
