2 General provisions
The design conditions of storage tanks shall not be less than the following2.0.1.1
Volume, diameter or height of the tank
Type of medium and its density:
Operating pressure (positive and negative pressure) and operating temperature of the tank Earthquake fortification intensity, wind load, snow load, air temperature; corrosion allowance;
Open pipe size, form, quantity, flange specifications; Installation position of accessories:
Basic conditions.
Accessories only refer to the fixings fixed to the tank body by welding. Note:
The volume range of the tank should be 60-2000m
The design pressure should be the maximum decay pressure of the gas phase space of the tank. The design pressure range is -0.5~2.0kPa
2.0.4The design temperature should be the highest or lowest temperature that the tank metal may reach when the tank is in normal operation. The design maximum temperature should not be higher than 90℃, and the minimum temperature should not be lower than 19℃. In cold areas, for storage tanks without heating or insulation, the design temperature should be the lowest daily average temperature in the construction area plus 13℃. 2.0.5 The design of storage tanks should take into account the influence of corrosion of the medium in the tank and the corrosion of the marine environment and the service life. The corrosion allowance should be 15~2.0mm. 2.0.6 The thickness addition should be determined by the following formula: C= C, + C?
Where C----thickness addition, m;
