Refractory-Lined Composite Pressure Vessels

Abstract

Refactory lined pressure vessels, possessing good corrosion and erosion resistance at low and high temperatures, seem to be ideal for extending the wear life of conventional gun tubes. Since refractory materials exhibit high compressive and low tensile strength, prescribed residual stresses must be introduced to eliminate the significant tensile stresses produced during firing. The prominent problem in fabricating such vessels is to restrict the refractory material from expanding axially during the application of the residual stresses. This report presents manufacturing procedures to prevent the axial expansion; theoretical and experimental analyses predicting the residual and firing stress state in the vessel; and test results on 12.5 mm and 60 mm ceramic liners. Preliminary work on 6.4 mm Tungsten-Carbon Alloy is also reported.
