Abstract: As China's economic and social development, the state to reduce energy consumption, energy-saving emission reduction policies, continued to deepen，Thermal power unit to keep the high-parameter, large-capacity develop in the direction。Domestic supercritical, ultra supercritical boilers began to large, concentrated efforts to build and put into operation in，Generating units have been put into operation from the trial operation and put into operation after the operation point of view, frequently burst pipe is troubled super, ultra-supercritical unit in a major problem。Cutting tube inspections to carry out this work is not long, experience, not many。This paper describes xing chang Plant 2×660MW USC In the construction process the site of cutting tube inspections, inspection methods, inspection results, etc. are introduced
Key words: New Units; Boiler Explosion; Cutting tube inspections; Case Study
