API Std 650 flat-bottom oil storage tanks anchorage forces

Oil storage tank with floating roof structure: The floating roof in the API Std 650 flat-bottom oil storage tanks oil storage tank can effectively reduce the volatilization consumption of oil, because the gas space on the oil liquid surface in the floating roof storage tank is small, the exhaust volume is low, and the breathing loss is very small. That can reduce the volatilization loss caused by the "big breath" of the API Std 650 flat-bottom oil storage tanks. Strengthen the inspection and maintenance of API Std 650 flat-bottom oil storage tanks: regularly check the sealing conditions of oil storage tanks, and check and maintain important auxiliary equipment to ensure good sealing performance.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 Std 650 flat-bottom oil 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 interior of API 650 storage tanks to be internally lined or coated must have all edges rounded to a minimum of 3 mm radius. Internal welds must be completely seal welded, ground smooth, and free from API Std 650 flat-bottom oil storage tanks surface porosity, pockets, and high spots. Remove weld spatter. Vendor as specified on API 650 storage tanks drawing must perform additional surface preparation.The company's quality is first, the price is reasonable, the construction period is guaranteed, and the purpose of abiding by the contract, our steel API Std 650 flat-bottom oil storage tanks products have received high recognition from customers from the world.
