Abstract
ABSTRACT: Apparently no analytical method is available to analyze the bolt tension in a flanged pipe joint subjected to flexure taking into account the actual stress distribution at the joint. Conventionally, a method similar to the flexural analysis of beam is sometimes applied on the assumption that bolt tension is proportional to the distance from neutral axis which is far from the actual stress condition. In this paper, an investigation has been carried out to find the effects of various parameters relating to flanged pipe joint connection, so that a definite guideline on determining the bolt tension can be developed. In addition, results are compared with the conventional analysis. To carry out the investigation, a flanged pipe joint subjected to bending has been modeled using finite element method, which also includes contact simulation. In this analysis, shell element has been used for the modeling of pipe and flange. Non-linear spring has been used to model contact surface and bolt. Non-linear finite element method has been used to find out results till failure by yielding of pipe. Joint has been subjected to ultimate moment and under this moment; the maximum bolt tension has been evaluated. Based on the study, an attempt has been made to present a guideline to find out bolt tension that is structurally effective for a flanged pipe joint. The whole process is carried out under various parametric conditions within certain range. It has been found that some parameters like flange thickness,
