How to limit the release of liquid contents from API standard 650 welded steel oil storage tanks

Some defects may be found after the regular safety inspection for the API standard 650 welded steel oil storage tanks. The common API standard 650 welded steel oil storage tanks defects are: Tank cracks, tank welding defects The cracks on the base metal, surface and near surface of the tank wall shall be eliminated by grinding with circular arc, and then magnetic particle inspection or re inspection shall be carried out Cracks in heat affected zone: generally, grinding method is used to eliminate cracks, and magnetic particle or dye flaw detection is used to confirm that there is no crack, and then repair welding or grinding smooth transitionChanges in Tank ShapeIf in any of the foregoing tests there is an excessive rise of the bottom of the tank around the boundary of contact with grade, or off its foundations, or if any of the specified conditions of test loading cause other appreciable changes in the shape of the tank, the design shall be reviewed and means shall be provided in the tank for holding the shape within permissible limits under all conditions of loading,API standard 650 welded steel oil storage tanks. Additional TestsThe tests prescribed in API 620 tank 7.18 are believed to be sufficient for most tanks constructed according to these rules; if, in the opinion of the designer, additional tests are needed to investigate the safety of a tank under certain other conditions of loading, as determined from the design computations, these tests shall be made on the tank involved in addition to the tests specified in this standard.API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API standard 650 welded steel oil storage tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.Management concept: integrity is the cornerstone, talent is the foundation, and service is the key.Business philosophy: to keep faith, to win by quality, customer first, win-win development.Based on integrity, win customers with good reputation, win competition with excellent product quality, improve service with customer orientation, and pursue the goal of win-win development in cooperation with customers.Sincerely welcome customers to visit and negotiate business.Our company has strict quality control standards.
