NUMERICAL INVESTIGATION OF SAFE TIGHTENING FOR FLANGE IN OIL PIPE LINE

Rise in the population is increasing day by day with the increase in population Transportation and energy needs in the society is also increasing to sufficiently provide fuel to satisfy the demand more and more oil pipelines is installed every day one of the important aspects in any pipeline is to connect the couplings between Pipes with Flanges in most of the cases the flange failure or rotation occurs with inappropriate tightening or more tightening the project will be done using different ratios of bolt Pretension loads and find out what kind of stresses is occurring in the flange that leads to flange failure, 5 tightening percentages are used in this project to see the optimal tightening vs gasket compression with occurring flange stress Gasket thickness of 1m and 2mm is assumed for full compression in Spiral wound gasket All the flanges designed in the project will comply with ASME B16.5 standard. 3d modeling is done using Solidworks and The simulation at multiple bolt loads is done in Ansys.
