Improving Reliability of Bolted Flanged Joints

Author: Robert C. Davis, P.E., Consulting Engineer II

ASME VIII-1 Appendix 2 flange design rules states flanges should be sufficiently robust to withstand the stresses produced by operating loads; however, what happens if those flanges leak during operation? Do you know what options are available to reduce or eliminate the potential risk of leakage in bolted flange joints? In this article, Bob Davis introduces several options to evaluate bolted flange designs with the goal of minimizing the risk of leakage without risking damage to any of the joint components.
