API 650 duplex stainless steel tanks roof support legs sleeves
If additional requirements are met, higher internal pressures are allowed. API 650 only covers tanks that support the whole bottom evenly and API 650 duplex stainless steel tanks tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. It requires that you have a minimum material thickness of 3/16 inch.
When encountering heavy rain or continuous heavy rainfall, the safe operation of API 650 duplex stainless steel tanks will be affected. For example: the API 650 duplex stainless steel tanks is submerged, the oil unloading valve and the flame arrester valve are broken by water and the oil tank leaks. The oil tank area must do emergency work to prevent rainstorm to ensure the safety of the oil tank. Here are some safety protection measures for API 650 duplex stainless steel tanks in heavy rain.
The API 620 large storage tank nozzle neck is fabricated by welding from 1/2-in. plate. The materials in the tank wall, the nozzle neck, and the reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank wall are fully radiographed, double-welded butt joints. The longitudinal joint in the nozzle neck is of the same type API 650 duplex stainless steel tanks but is not radiographed; however, the longitudinal joint and all other parts of the nozzle-and-wall-plate assembly have been shop stress relieved after fabrication, as required by 5.25. The adequacy of the reinforcement and attachment welds shown in Figure F-6 shall be determined.

The mode of iron and API 650 duplex stainless steel tanks steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API 650 duplex stainless steel tanks steel logistics.
