Study of Effect of Angle of Contact and Angle of Extension of Wear Plate on Maximum Stress Induced in Horizontal Pressure Vessel

Abstract

Horizontal Pressure Vessels are supported by two saddle supports near the ends. There is a local stress concentration in the vessel near the saddle horn of the saddle support. The parameters of a saddle support that can be changed are the angle of contact of the saddle, the width of saddle, the width of wear plate, and extension of the wear plate over the saddle horn. These parameters directly govern the values and location of maximum stress in the vessel. The aim of this study is to perform FEA analysis and find the effects of different configurations of the saddle and its effect on the maximum stress in the vessel and thus find the most optimum configuration of the saddle to pass the ASME requirements while keeping the material costs at the minimum.
