API standard 650 aboveground oil storage tanks anchor straps
Shell Stiffening Rings for Tanks That Contain Liquid: Internal or external shell stiffening rings may be required to maintain roundness when the API standard 650 aboveground oil storage tanks is subjected to wind, vacuum, or other specified loads. When stiffening rings are required, the stiffener-to-shell weld details shall be in accordance with Figure R-1 and R.3.5.2 through API Standard 620 R.3.5.5. Three-plate laps or butt-weld junctions in the tank bottom shall be not closer than 12 in. from each other and/or the butt-welds of the annular plate.
API 650 can store oil, gas, chemical, water and biofuel for some of the most common tanks in the oil industry. API 650 can store contents at a lower pressure (maximum of 2 PSI) but at much higher temperature (-40 degrees F to 500 degrees F) than the standards of API standard 650 aboveground oil storage tanks. It can be any tank size.
The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.
}X-ray inspection is mainly applicable to the internal inspection of pressure bearing parts and materials of metal oil tanks such as API standard 650 aboveground oil storage tanks. It can clearly find the blocky defects inside the welded joints. However, the cost and resource consumption of radiographic testing are large. Magnetic particle testing can effectively detect the surface and near surface defects of API standard 650 aboveground oil storage tanks etc. metal oil tanks, but magnetic particle testing can not effectively identify the internal defects of oil tanks.
The results of adopting two-level API standard 650 aboveground oil storage tanks service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and API standard 650 aboveground oil storage tanks after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
