A few days ago, Shandong Steel plant overhaul workshop power maintenance class staff with a small plugging rod, solved the special-shaped rolling workshop heating furnace drum steam pipeline leakage problem, to ensure stable production, save outsourcing costs of nearly ten thousand yuan.

Not long ago, a three-way weld of steam pipeline of heating furnace drum in special-shaped steel rolling workshop was welded. Steam leakage made the pressure of drum drop, so it was urgent to implement plugging operation. However, a 3cm long weld stumped the operators, because of the requirements of the process and production rhythm, the operation can not stop the furnace and steam, only with pressure plugging, the team can not meet the requirements of the existing welding facilities with pressure plugging. The workshop power maintenance class staff after consultation, if the professional outsourcing team with pressure plugging, not only to pay 10,000 yuan costs, and it takes about 3 days to complete. In line with the idea that all costs can be reduced, the power maintenance team immediately organized a capable force and decided to overcome the difficulties by using the plugging rod to implement pressure plugging. However, difficulties ensued in the construction. The steam pipeline was only 10 cm above the ground, and the crack was located right below the pipeline, so the space was very narrow. In order to accurately repair, plug and fix the pipe jam, the operators almost pressed their faces to the ground. After intense construction and pressure test, the sealing with pressure is successful, which meets the production demand.
