API standard 650 aboveground welded storage tanks with a ringwall foundation

The main types of metal storage tanks are vertical dome roof tank, vertical external floating roof tank, vertical inner floating roof tank, spherical oil tank and horizontal oil storage tank. API standard 650 aboveground welded storage tanks is vertical tank. The capacity of vertical dome roof oil storage tank is generally less than 10000 cubic meters. The wall plate adopts sleeve type fillet weld, and it is usually installed by inverted or forward installation method during construction.Thickness as it Affects Preheat and Post-heat Requirements
Plate with thicknesses below 1/2 in. is reasonably notch tough. In most steels, when the API standard 650 aboveground welded storage tanks used plate thickness exceeds 3/4 in. – 1 in., notch toughness, particularly as welded, decreases sharply. The decrease in notch toughness can be minimized by the conventional post-heat treatment and, in many steels, by preheat treatment. The benefits of preheat treatment in steels 3/4 in. – 1 in. thick have been demonstrated; similar benefits could be expected in thicker steels, but sufficient experimental data are currently lacking.The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API standard 650 aboveground welded storage tanks API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.Since its inception, the company has always adhered to the development policy of "survival with quality, development with products, cooperation with credibility, and service with customers".
