摘要
Abstract
In this paper,a sampling test is carried out on the P22 steel main steam pipe of a 320MW unit running for 216000 hours in a power plant,and the life of the test results is evaluated.The results show that although the performance of the base metal of the main steam pipe has declined,the structure has not been obviously deteriorated,and no creep hole has been seen.Under the premise of standard operation and supervision,maintenance and maintenance of the unit,according to the estimated average annual operation hours of 6 500 hours/year in the future,the unit can continue to operate safely for more than 10 years.关键词
