API standard 650 flat-bottom tanks snow load
The refrigerated tank primary components shall also include those parts of a single-wall or an inner tank that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature. Such API standard 650 flat-bottom tanks components include roof plates, roof manways and nozzles with their reinforcements, roof-supporting structural members, and shell stiffeners when the combined tensile and primary bending stresses in these components under design conditions are greater than 6000 lbf/in.2.
API 650 is the standard for welded tanks for oil storage. It specifies the API standard 650 flat-bottom tanks design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.
Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed API standard 650 flat-bottom tanks materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.
}Requirements for prefabrication of the top of large vertical API standard 650 flat-bottom tanks: The prefabrication of the tank top shall be prefabricated in blocks according to the drawings. Pay attention to the spacing of the welds after installation when setting out the material. Reinforcing ribs should be formed and inspected with an arc-shaped template. When a single top plate needs to be spliced, butt joints should be used. The forming of a single top plate should be welded between the reinforcing ribs and the top plate on the mould. After forming, check with an arc-shaped sample plate, and the gap should not be greater than 10 mm.
