ASSEMBLY PERFORMANCE OF A GASKETED BOLTED FLANGED PIPEJOINT USING DIFFERENT BOLT TIGHTENING STRATEGIES

This paper presents the results of the assembly process of a gasketed bolted flanged pipe joint for two different bolt tightening strategies, i.e. ASME and Industrial using torque control of preload method. The final clamping force is achieved in four and five passes in ASME and Industrial strategy respectively. Axial bolt stress variation, at the end of each pass, individual bolt bending behavior, gasket stress and flange stress variations for both strategies are discussed.
