Due to irregular operation of API standard 650 ground supported tanks welding, there are many weld deformations during the construction process. Before specific operations, most construction units have formulated relatively complete construction plans and set up special welding process instructions, but the operators have not fully performed welding in accordance with various process guidance requirements and construction specifications, resulting in some quality problems of oil storage tanks. How can we reduce or even avoid this kind of situation?
API standard 650 ground supported tanks Pressure-relieving DevicesTanks shall be protected by automatic pressure-relieving devices that will prevent the pressure at the top of the tank from rising more than 10% above the maximum positive gauge pressure except as provided in API 620 standard 9.2.2.Where an additional hazard can be created by the exposure of the tank to accidental fire or another unexpected source of heat external to the tank, supplemental pressure-relieving devices shall be installed. These devices shall be capable of preventing the pressure from rising more than 20% above the maximum positive gauge pressure. A single pressure-relieving valve may be used if it satisfies the requirements of this paragraph and 9.2.1.
The working pressure of the low-pressure storage tank is greater than that of the atmospheric storage tank, but its pressure is less than 0.1MPa. API 650 petroleum storage tanks are classified according to their environment: Above-ground storage tank: refers to the bottom of the storage tank at the design elevation of API standard 650 ground supported tanks and above; the bottom of the tank is below the design elevation of +0.00 but not exceeding.
