An Update on Quantifying Bolt Relaxation During High Temperature Operation
A summary of testing related to bolt relaxation, which occurs at temperatures above 230°C (450°F) was presented in a previous paper. The work has since been extended to include lower temperature data for common bolting materials. This paper provides a summary of the additional work performed and further observations regarding the acceptable design limits for A193-B7 and A193-B7M bolt materials. In addition, a conclusion regarding the recommendations made in API RP751 comparing A193-B7 and A193-B7M relaxation is made.
