SLEEVE WITH RELIEF CAVITY FOR FLANGED TUBE ASSEMBLY
Last updated:
Abstract:
A flanged tube assembly includes a rigid tube (10) and a sleeve (12) disposed about an axial end portion of the tube. The axial end portion (18) of the tube (10) includes a flange portion (24) that is formed by the tube wall (36) being radially outwardly deformed over an axial end surface of the sleeve. The sleeve (12) has a radially inner surface (28), and a portion of the tube wall (36) inside of the sleeve (12) is deformed to engage and conform to the radially inner surface of the sleeve, thereby forming a non-welded connection between the sleeve and the tube. The radially inner surface of the sleeve proximal the flange defines a relief cavity (56) that receives the deformed portion of tube wall when the tube wall is deformed during the formation of the flange (24).
