Behavior of gasketed bolted pipe flange joint under combined internal pressure, axial, and bending load: Three-dimensional numerical study

Abstract

Optimized performance of joint is categorized by its ''structural integrity'' and ''sealing capability''. In literature, limited data are available regarding the performance of gasketed bolted flanged joint under combined internal and external loading; hence an optimized joint performance cannot be addressed. In this paper, a detailed three-dimensional nonlinear finite element analysis of bolted gasketed flange joint is performed, to study its performance under combined internal (pressure) and external (axial and bending) load. Results of the finite element analysis are compared with the experimental results available in literature providing the validation of the numerical approach developed.

Dynamic buckling response of buried X70 steel pipe with bolted flange connection under two-charge explosion loads

“…Bolted flange connection (BFC) and welding connection are the two extensively used modes to connect long-distance transport pipes [ 4 , 5 ]. Many previous studies have presented that BFC can effectively improve the sealing performance and reduce the leakage rate of pipes [ 6 , 7 ]. The studies on the mechanical behavior of pipes with BFC are also getting more attention to ensure the safe operation of the pipes due to intensive construction of urban pipe networks [ [8] , [9] , [10] ].…”

Combined loading performance analysis of gasketed bolted flange joints with emphasis on bolt scattering

“…The effects of different bolt tightening strategies on the strength of the joint have been discussed without the application of internal pressure [9] as well as under the joined action of pressure and axial load [10]. The impact of bending load and internal pressure on the joint integrity has also been studied with axial loading [11] as well as without axial loading for both single and double gasket joints [12].…”
