Analysis of Coated-after Superheater Pipe Bursting Accident in Utility Boiler

摘要：

　　Pipe failure accidents (bursting) are frequent in thermal power plants,and severely influence the safe and economic running of power generation units.The authors analyzed the possible causes and features of coated-after superheater pipe bursting in boilers.Taking the coated-after superheater pipe bursting accident in a power plant for an example,the authors conducted macroscopic topography analysis,running environment analysis,metallurgical analysis,chemical composition analysis and strength analysis of the bulged pipe,ruled out that the coated-after superheater pipe bursting was caused by superheating,and demonstrated that the bursting was caused by crack defect that had not been found during regular inspection.
