| Abstract: | Directing against problem of frequent tubeburst for horizontal coil pipe in group NO.5 in lowtemperature reheater of boiler NO.2 of Wannengda PowerGeneration Co Ltd, it is believed through sample analysis that the main cause is due to unreasonable structure and welding defects of original support pads. Combined with major repair, the pipe panel situated in hightemperature area has been replaced, and new support pad structure being adopted, making the abovementioned problem to be solved. |
