Abstract
The continued development of plastics with improved corrosion resistance has extended the conditions in which plastics can perform 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 conditions. This type of composite structure consisting of a steel vessel lined with a plastic membrane protected by brick set in resin and/or 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 conditions. The process conditions must be accurately detailed and the lining 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 state 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 die analysis of the lining.
