热应力对管道的破坏

Pipeline destroyed by thermal stress

热力系统管道在交变温度作用下会产生交变应力、热应力集中区域金属易造成疲劳 ,当疲劳到达极限值时产生破坏 ,形成裂纹。采取适当的措施进行处理和预防 。

Resulted by the action of alternative temperature,the pipeline of thermodynamics system will generate a kind of alternative stress,the metal in the focus region of thermal stress will wear out up to crack.As long as the adaptive measures are taken,it will prevent crack from generating efficiently.
