API 650 welded steel oil storage tanks allowable longitudinal membrane compression stress in shell

Some defects may be found after the regular safety inspection for the API 650 welded steel oil storage tanks. The common API 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 transition.

The inner layer of API 650 tank is the same as that of single layer tank. It is made of high-quality steel plate in strict accordance with the standard of "steel welded atmospheric pressure vessel". The thickness of API 650 welded steel oil storage tanks steel plate reaches the standard and the service life is longer.
