| Abstract: | The high temperature reheat steam pipeline of some power plant is abnormally sinking after blowpipe and the con-stant force spring hanger is generally lying in a limit inferior location.Therefore,this paper tries to find out the main reason for sinking on the basis of analysis and proposes disposal measures of newly increasing three groups of constant force spring hangers and changing two groups of constant force spring hangers and related precaution suggestion for preventing sinking of the high temperature reheat steam pipeline.The problem of sinking of the steam pipeline is effectively solved after imple-menting the above disposal measures. |
