API Std 650 self-anchored flat-bottom steel tanks impulsive water parameters
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 Std 650 self-anchored flat-bottom steel tanks and above; the bottom of the tank is below the design elevation of +0.00 but not exceeding.
In order to prevent the deformation of the bottom of metal vertical API Std 650 self-anchored flat-bottom steel tanks during welding, comprehensive control measures such as strict control of assembly geometry size, reasonable welding procedure, process control of welding deformation and rigid fixation are adopted during assembly welding. The specific methods are as follows:1. Strictly control welding groove forming of API Std 650 self-anchored flat-bottom steel tanks.2. Strictly control the size of tank welding seam assembly.3. Define the welding sequence of tank bottom plate.4. Reasonable distribution of welders.
Insulation LoadFor API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API Std 650 self-anchored flat-bottom steel tanks roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.
BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.
