API standard 650 mixed material tanks convective (sloshing) period

The manufacturing requirements of bottom plate of vertical metal tank, API standard 650 mixed material tanks are as follows: 1. In order to compensate welding shrinkage, the layout diameter of tank bottom is 5-2mm than the design diameter; 2. The butt joint of edge plate of tank bottom shall be machined automatically or semi-automatically; 3. The distance between any two adjacent welding joints on the tank bottom plate and the distance between the butt joint of edge plate and the longitudinal weld of bottom ring wall plate shall not be greater than 200 mm.

Testing the Outer Tank: While the test pressure is being held, all welded seams and connections in the outer shell and roof shall be thoroughly inspected with a solution film unless they were previously checked with a vacuum box. The API standard 650 mixed material tanks air pressure shall be released. Pressure relief and vacuum relief valves shall be checked by applying the design gas pressure to the outer tank, followed by evacuation of the outer space to the vacuum setting of the relief valve.

The American standard API 650 design has been widely used. We can use our existing professional design knowledge to serve the construction projects of large API standard 650 mixed material tanks storage tanks, oil tanks and water tanks. The company is a small and medium enterprise that can provide American standard API 650 design software, design qualifications, and design capabilities.
