摘要：PURPOSE:To manufacture a steel-aluminum united pipe light in weight and excellent in mechanical properties, by inserting an aluminum pipe into a steel pipe or inserting the aluminum pipe by interposing a high-power adhesive material between both pipes and applying an internal pressure to adhere them firmly to each other through their whole bodies or adhere them together by squeezing them at places. CONSTITUTION:An aluminum pipe is inserted into a steel pipe so that both pipes are in tight contact with each other or a powerful adhesive material is interposed between both pipes to adhere them firmly to each other by applying an internal pressure to expand the inner pipe. Further, squeezing is preferably applied at places to adhere them firmly together. Thus, a steel-aluminum united pipe light in weight and excellent in mechanical properties is inexpensively and easily manufactured.
