Structural strength: gasketed Vs non-gasketed flange joint under bolt up and operating condition
Muhammad Abid,David Nash +1 more
TL;DR: In this paper, the authors present results of an experimental study of the behavior of the stress variation at the flange of a gasketed and non-gasketed flanged pipe joints during both the bolt up (preloading) and operating (internal pressure loading) conditions.

Novel Formulation of Bolt Elastic Interaction in Gasketed Joints
Sayed A. Nassar,Xianjie Yang +1 more
TL;DR: In this paper, a novel formulation was proposed for studying bolt elastic interaction during the tightening of a group of fasteners in flat faced gasketed joints, which was used for developing tightening strategies that would achieve a more uniform clamp load in the flange at initial assembly.

Prediction of Leakage Rates through Sealing Connections with Nonmetallic Gaskets
Boqin Gu,Ye Chen,Dasheng Zhu +2 more
TL;DR: In this article, a model of gas leakage through nonmetallic gaskets was developed in order to predict leakage rate of gasket sealing connections, and the model was verified by the leakage experiments on two types of Gaskets: compressed non-asbestos fiber gasket and flexible graphite gasket reinforced with tanged metal sheet.
