Pipe joint and method for manufacturing the same

摘要

A tubing coupling and a method for connecting tubing sections in which one tubing section is placed upon another tubing section in an overlapping manner. The first tubing section (1) is enlarged in the cold state in the area (2) where it overlaps, and the enlarged area is then placed over the second tubing section (3). Subsequent heating of the enlarged area (2) results in shrinkage of the first tubing section (1) which produces a firm seating of the first tubing section (1), for example a plastic suction tube as an air inlet tube, on the second tubing section (3), for example a flange for attachment to the cylinder head of an internal combustion engine.
