The continued development of plastics with improved corrosion resistance has extended tie conditions in which plastics can pafonn satisfactorily as corrosion resistant linings on steel. The use of a masonry lining over the plastic “membrane” further extends the conditions of service to higher temperatures and more severe mechanical ocnditions. This type of composite structure consisting of a steel vessel fined with a plastic membrane protected by brick set in resin and an inorganic mortars presents a number of design challenges, The composite structure must be selected to perform satisfactorily in the chemical environment and be designed to perform satisfactorily in both the steady state and the transient process condition. The process
conditions must be accurately detailed and the Iining design must consider the response of several materials with widely differing physical properties to these conditions. Computer software has been developed which will calculate and graph the temperature gradient through the composite lining and calculate and graph the stresses in the lining for both steady stale and transient process conditions. This paper covers the process information necessary for the specification and design of a brick and membrane lining in a steel vessel and the use of a computer for the analysis of the lining.
