Regarding the assembly process of the cylinder and the head of the storage tank:

1) The right head is paired with the cylinder body, the outer side is welded by manual arc welding, the inner side is welded by manual arc welding, the outer carbon arc gouging is used to clean the root and the metal luster is polished with a grinding wheel, and the outer side is submerged arc welding.

2) The welding seam of the right side head and the cylinder body has passed 100% radiographic inspection to class II.

3) Assemble the internal connection pipe and transition joint of the cylinder body, argon arc welding point solid, argon arc welding.

4) Clean the inside and degrease the parts locally.

5) The left head and the cylinder are assembled, the root is fixed with argon arc welding, the root is sealed with argon arc welding, and then one layer is welded by argon arc welding, and one layer is welded by submerged arc welding with low current. According to normal current submerged arc welding surface.

6) The welding seam of the left side head and the cylinder body has passed 100% radiographic inspection to class II.

7) Assemble the inner piping and the cylinder, and weld by argon arc welding.

8) Group butt welding adsorption device, argon arc welding.

9) Group butt welding of longitudinal bracing pads and bracing. When the backing plate is welded, there is a 20mm non-welded area on the left side.
