Before entering the drum, the waterwall pipe is straight between the waterwall and drum? If it is, maybe because all the heat stress between waterwall and drum (due to the heat expansion) is put to the pipe which is damaged. So you can bend this pipe for two times, then the pipe can expand freely.
Hope this can help u
