The opening pressure or vacuum of the pressure relief and API620 petroleum storage tanks vacuum relief valves shall be checked by pumping air above the water level and releasing the pressure and then partially withdrawing water from the tank. After the tank has been emptied of water and is at atmospheric pressure, the anchorage, if provided, shall be rechecked for tightness against the hold-down brackets. Air pressure, equal to the design pressure, shall be applied to the empty tank, and the anchorage, if provided, and the foundation shall be checked for uplift.

The company has been engaged in the design, construction and installation of foreign API 650 standard API620 petroleum storage tanks storage tanks for a long time. It has the international qualification of ASME welding technology, has the design ability of API 650 oil tanks and API 650 storage tanks, and has pressure vessel design and manufacturing license and GC pressure pipeline installation license. Certificate, API620 petroleum storage tanks petrochemical equipment pipeline general contracting qualification, safety production license, international trade import and export license.

When welding API620 petroleum 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.
