API 650 stainless and carbon steel tank base metal

Combination of Design Loads
The inner tank API 650 stainless and carbon steel tank shall be designed for the most critical combinations of loading that result from internal pressure and liquid head, the static insulation pressure, the insulation pressure as the inner tank expands after an in-service period, and the purging or operating pressure of the space between the inner and outer tank shells, unless the pressure is equalized on both sides of the inner tank.

API 650 petroleum storage tank stipulates that if the thickness of the lower siding obtained by calculating the anti-overturning moment is greater than the thickness of the API 650 stainless and carbon steel tank hydrostatic pressure test (both do not include the corrosion margin), the calculated thickness of the above siding required by the hydrostatic pressure is It should also be increased by the same proportion, unless special analysis is performed to determine the seismic overturning moment and corresponding stress at the bottom of each layer of API 650 petroleum storage tank wall.

"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and API 650 stainless and carbon steel tank product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."

In the actual welding of API 650 stainless and carbon steel tank, operators will use more arc-shaped plates for tailor-welding to better adapt to the larger volume of oil storage tanks. In order to effectively control the deformation of the welding seam of the API 650 stainless and carbon steel tank, a scientific and accurate prefabricated bottom plate is required. In the process of prefabricating the bottom plate of the oil storage tank, it is necessary to strictly follow the technical requirements for the construction of the oil storage tank. At the same time, it is also necessary to clarify the external dimensions according to its actual manufacturing standards so that it has sufficient shrinkage.
