Repair of leaking steel drum

1. Repair method of steel drum (1) Traditional repair method——Charging characteristics of gas welding trap: The heat affected zone is relatively large, which can cause surface oxidation, deformation of the barrel body, burning of the sealant in the crimping edge, and a little leakage must be repaired. ring. (2) Brazing repair method Features: The heat affected zone is relatively small and will not cause the barrel to form. However, the pre-weld treatment is more complicated and the work efficiency is low. (3) Argon arc welding repair method Features: The heat affected zone is relatively small, no surface oxidation occurs, the repair welding effect is good, and the work efficiency is relatively high. (4) Adhesive bonding method Features: low cost, high work efficiency, simple operation, but limited application. 2. Emergency repair method for steel drums (1) Epoxy resin trapping method First make up the leaking glue, then add it into the joint of the barrel and dry it, but the scope of application should be noted. (2) Roller re-pressing method must be returned to the factory, using a smaller-sized grooved roller, and then rolling on the sealing machine once, can reduce the leakage of more than 80%.
