“…2.1 Modelling and Abid & Baseer (2007) investigated joint strength and sealing capability under combined loading for an axi-symmetric 3-D model where the pre-load of each bolt was the same using a solid plate gasket. In this study, a complete 360 degree FE model was developed to study the effect of each bolt tightening on others.…”

Gasketed bolted flange pipe joints are always prone to leakage during operating conditions. Therefore, performance of a gasketed flange joint is very much dependent on the proper joint assembly with proper gasket, proper gasket seating stress and proper pre-loading in the bolts of a joint. For a gasketed flange joint, the two main concerns are the joint strength and the sealing capability. To investigate these, a detailed three-dimensional nonlinear finite element analysis of a gasketed joint is carried out using gasket as a solid plate. Bolt scatter, bolt bending and bolt relaxation are concluded as the main factors affecting the joint's performance. In addition, the importance of proper bolt tightening sequence, number of passes influence of elastic and elasto-plastic material modelling on joint performance are also presented. A dynamic mode in a gasketed joint is concluded, which is the main reason for its failure.

“…Research [4][5][6][7] on the strength of the flange joint has been conducted to calculate the contact pressure of the gasket and the flange groove, which has a significant effect on the sealing capability, including the bolt load [8,9]. Also, studies on the sealing capability [10,11] were carried out to measure the leakage through experiments where the flange assembly was subjected to internal pressure in a given temperature.…”

:Gaskets are usually used for the sealing of flange joints. The joint is usually composed of two flanges, a ring gasket and clamping bolts. The metal ring gasket is suitable for pipe flanges, pumps and valve joints in high temperature and high pressure environments. A very high surface stress is developed between a ring type joint gasket and the flange groove when the ring type joint is bolted up in a flange. The dimensions of flanges and ring joint gaskets for the pipe sizes that are in common use are specified in the ANSI codes. However, sometimes it is necessary to make a new design for the flange joint which is not specified in the codes, as the equipment is getting larger and larger in size. This paper presents the contact behavior of Class 600 ring joint gaskets with oval and octagonal cross sections. Five different sizes of gaskets are employed in the analysis, and one of them is newly designed on the basis of analysis results obtained from existing models. Three load steps are used to find the stress, stain and contact pressure etc., and to compare the contact characteristics among the models due to the bolt clamping force and the working surface pressure. ANSYS Workbench version15 is used to conduct the finite element analysis.

“…This flange is usually called gasketless, or metal-to-metal, and the leakage of the pressurized fluid inside the vessel is prevented by the bolt preload. Bolted flanges have been widely investigated, however most studies are limited to the compact geometry design for connecting pipes [2][3][4][5][6][7][8][9][10][11][12][13], while others are dedicated to the deformation behavior of the gasket [14][15][16][17][18][19][20]. Research on flanges is usually focused on the structural stiffness, stress distributions, and the strength optimization of the flange parts, under bolt preload and internal pressure or other external loadings [2,3,[6][7][8][9][10][11][12]18,[21][22][23][24][25][26][27][28][29].…”
