摘要： A novel tube material, and method of forming the tube, are described. The tube has an inner liner, preferably flexible, an intermediate layer of in situ molded expanding foam material, and a flexible outer liner. The tube is rigid, with the structural strength derived entirely from the intermediate layer. The preferred method of construction uses an inner core which is used to hold the inner liner in place during forming. The inner core includes a mechanism to reduce its diameter, to facilitate removal after curing of the foam.
