The application of plastic linings to steel structures and the fabrication of dual Iamina vessels involves a number of steps. These may include heating, stretching, adhering, welding, and testing. The combination of these steps together with stresses associated with the liner extrusion process may be cumulative when multiplicative to the overall stress of the liner affecting its integrity and performance in a lined steel or dual laminate vessel. This paper will review the methods of testing and evaluation adopted by our company to insure the maximum performance of vessel lining materials.
