In the construction projects such as oil, pesticides, and chemical industry, the advantages of large -scale vertical cylindrical vault storage tanks have been widely used in the large -scale vertical cylindrical arch storage tanks. Welding electric gourds are widely used in oil tank construction. The improvement method of improvement is as follows:
1.After the tank is installed, install an electric gourd to improve the device. A uniform layout and 20 pillars are installed at about 500mm from the inside of the tank wall. The pillars and the bottom of the can are firmly welded. Align with the reserved window of the tank top. Slip. Each pillar is close to a 10T electric gourd on the side of the tank wall. The electric gourd should be on the vertical line with the hanging ears on the swelling circle.
2. Install the expansion circle at about 100mm at the lower end of the tank wall, so that the expansion circle and the tank wall form an integrated force. Welded the hanging ear on the expansion circle, and the electric gourd control was used to improve the liquid ears and the expansion circle to improve the tank wall.
3. After the installation of the device and the expansion circle is completed, the second circle of the wall is enclosed. After welding the outside of the longitudinal seam, you can start to improve the tank wall.
4. Before the improvement, check whether the expansion ring is tight, whether the dragon door card is welded, and whether the pillars are sloping are safe and reliable. After determining that the improvement device is correct, it can start to be promoted. When upgrading, first start the electric gourd one by one to make the load of each electric gourd basically consistent, and then start the entire gourd to improve. When the can, the person in the can to observe the operation of each electric gourd to prevent the card chain from being increased to the interface 150 ~ Surveying in 200mm position. Set a tank wall baffle every 1.5m along the lower end of the elevated wall plate, with a size of 120mm × 60mm × 8mm.
5. Start all the electric gourds again, so that the tank body is in place. Tighten the living mouth with 2 hand -pinoscis, measure the long -term, cut off excess wall board, polish the slope, and use it to weld it. Close to the tank wall, the lower end is close to the bottom of the tank, and the parts where the part is not in place is adjusted in place. The gap between the ring seam is adjusted with an electric gourd, and the point -to -point welding and welding are performed.
6. Install the 3rd circle board on the outside of the 2nd circle board. After the enclosure is welded, the vertical seam is welded, and after the longitudinal sewing is welded, repeat the above inspection to improve the second circle of the wall board. Seal the vertical seam, and the last group to the ring seam between the second and third circles. After the group is well welded, the swelling circle is falling after welding, and the lower mouth of the third circle of the wall is installed. Repeat the above process until the wall wall is installed. In the last 1 circle of wall boards, you need to leave a vertical seam without welding. After the seam group is paired, open the door here, remove the inverted device in the tank, and then seal the door and weld.
