Steel plate for bottoms of API 650 anchored liquid-storage tanks

The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API 650 anchored liquid-storage tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.

Determination of API 650 oil tank container: The total volume should be determined according to factors such as transportation mode and API 650 anchored liquid-storage tanks fuel supply cycle. For train and ship transportation, the maximum consumption is not less than 20-30 days; the maximum consumption for automobile transportation is not less than 5-10 days.

We supply 3500 tons SA387GR5CL1 steel plates to Pakistan. The main businesses of the Pakistan customer are manufacturing columns & towers, heat exchanger, waste heat recovery boiler, pressure vessel & reactors, tanks, etc. We arranged SGS test for the SA387GR5CL1 steel plates. The test contents include chemical composition analysis, tensile test, impact test, etc. The test results are satisfied. The Pakistan customer gave good feedback after receiving the SA387GR5CL1 steel plates.

When welding API 650 anchored liquid-storage tanks, in order to avoid weld deformation, it is necessary to use corresponding welding process according to the type of steel used in the tank, such as welding requirements of steel plate, welding position, etc. Reasonable arrangement of the assembly sequence, the use of subsection back welding and jump welding method, strict control of welding process parameters, rigid fixation measures, take corrective measures for deformation compensation are necessary.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent API 650 anchored liquid-storage tanks products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the API 650 anchored liquid-storage tanks technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
