Failure Analysis of Thermocouple Thimble

Abstract:

Article Preview

The failure analysis of a thermocouple thimble used in hydrogen pipeline of hydroforming cracking system is presented. In order to analyze the failure reason, detail checks and tests such as macroscopic check, chemical compositions analysis, residual stress test, mechanical property test, metallurgical structure and fracture analysis were carried out. Based on the results of investigation, the main causes of the failures are presented.
