Production Process of Storage Tanks

1. Measure the diameter of the joint after the head enters the factory and report it to the technical Department.

2. Cylinder feeding and beveling: the cylinder plate is fed according to the drawing, and the steel plate furnace batch number is stamped. The length and width deviation of the cylinder plate is +2mm, the diagonal deviation is +3mm, and the annular groove is opened on the T5 side.

3. 5 cylinder plates: roll the steel mark inside the cylinder for easy tracing. After the coil is rolled into the cylinder, the gap between the sample and the plate is qualified within 15mm: the error variable is less than 1mm. After positioning welding, weld drawing arc plate.

4. 5 tube joint longitudinal seam: Use a wire brush to clean impurities in the range of 20-25mm on both sides of the welding seam until the metal light is exposed on the arc plate 60-80mm away from the base metal to start the arc, arc after 60-80mm arc receiving plate, weld width 14~20mm, weld residual height 0~3mm.

5. Calibrating the circle: measure with the sample plate equal to the cylinder to ensure that the tolerance of roundness is 6mm.
