This standard specifies the requirements for the evaluation conditions, evaluation procedures, scoring calculations, evaluation grades and evaluation reports for the safety status of temperature sleeve sockets on pressure-bearing components of thermal power units in service. This standard is applicable to the safety status assessment of temperature bushing seats on headers, pipelines, valve bodies, and cylinders of thermal power units in service. The drainage (drainage) water pipe seats, exhaust air pipe seats, sampling pipe seats and pipe seats with similar connection forms on the pressure-bearing parts can be implemented as a reference.
