A method of coupling tubular bodies is provided, particularly for use in fluid handling systems requiring a fluid-tight, pressurized joint. One tubular body is made from a polymer. The other tubular body is formed as a laminate having a metallic layer and a polymeric layer (e.g., nylon coated aluminum tubing). The tubular bodies are positioned relative to one another (e.g., the laminated tubular body may be inserted within the polymeric tubular body when the polymeric layer of the laminated tubular body is outward of the metallic layer). The tubular bodies are then joined together by induction welding to cause heat transfer from the laminated tubular body's metallic layer to its polymeric layer thereby resulting in deformation of the polymeric layer and bonding of the polymeric layer to a surface of the polymeric tubular body, forming the joint. |
