As. Tooth et al., AN ALTERNATIVE WAY TO SUPPORT HORIZONTAL PRESSURE-VESSELS SUBJECT TO THERMAL LOADING, International journal of pressure vessels and piping, 75(8), 1998, pp. 617-623
When storing liquids at high temperature in horizontal vessels, the cu
rrent design methods aim to minimise the thermal stresses by introduci
ng a sliding surface at the base of one of the twin saddle supports. H
owever, regular site maintenance is required to ensure that adequate s
liding is achieved. This may be difficult and costly to carry out. The
aim of the present work, therefore, is to dispense with the sliding s
upport and to provide saddle designs which, although fixed to the plat
form or foundation, do not result in the storage/pressure vessel being
overstressed when thermal loading occurs. This paper provides general
recommendations for the most appropriate saddle geometries, and detai
ls the way in which design-by-analysis and fatigue-life- assessments m
ay be carried out using the stresses that arise from these designs. (C
