Experimental Research on High-Temperature Penetration Testing
In order to achieve the penetration testing of the high-temperature pipelines of operating units in power plants,it is urgent to conduct experimental research on high-temperature penetration testing.This study selects dif-ferent penetration testing agents to conduct penetration testing on specimens with natural defects at different tem-peratures,and compares the sensitivity of testing systems and testing results,so as to verify the feasibility and limita-tions of high-temperature penetration testing.It is found that good testing results can be achieved within the rec-ommended temperature range of penetration testing agents,but when the temperature of the tested component ex-ceeds the recommended temperature,testing process parameters must be strictly controlled to obtain good testing results,which provides a test basis for the development of high-temperature penetration testing processes.
