There are a large number of all kinds of copper storage tanks being built every year, and many old cans have been rebuilt. In this paper, the basis of new tank construction, floor arrangement, board uplift, assembly welding, due to improper arrangement of arches on the floor, blasting law widely used in the improper operation, lax control, floating motionless and falling , Tipping is not vertical and other quality accidents to analyze and propose corrective measures.
