152526 - Simulation of Bolt Interactions in Large Diameter Flanges for Gasket Assembly Training 

Abstract: 

A numerical model for bolt interactions in flange gasket assemblies has been adapted to large diameter flanges, with specific attention to an ASME B16.5 NPS 16-inch pressure class 300 flange. The original method, previously validated on ASME B16.5 NPS 4-inch blind flanges with a pressure class of 150, was adjusted to account for the increased complexities of larger flanges, such as greater bolt relaxation and more pronounced elastic interactions. The model was validated through experimental testing on an ASME B16.5 NPS 16-inch pressure class 300 flange, following a standard bolt tightening sequence as outlined in the ASME PCC-1 guidelines. These tests provided data for assessing the distribution of bolt loads and gasket behavior during assembly, helping to refine the model to address the interactions unique to larger flanges. The model captures the significant interactions between bolts during assembly, which become more complex as flange size increases. The adapted model is designed to improve gasket assembly training by more accurately simulating bolt-gasket interactions in larger diameter flanges. It helps trainees better understand how tightening sequences affect bolt load distribution and gasket compression. This tool reinforces the importance of following standardized procedures, such as ASME PCC-1, to prevent common installation mistakes. It aims to reduce gasket failures and enhance the reliability of industrial systems through better-informed assembly practices.
