Method and apparatus for connecting a tube to a machine
A connection of a tube to a machine includes a plurality of rolled grooves in a region of contact between the collet of a compression fitting and the tube. The grooves reduce the occurrence of fretting of the tube surface while a region of residual compressive stress formed in the tube proximate the...

| description | A connection of a tube to a machine includes a plurality of rolled grooves in a region of contact between the collet of a compression fitting and the tube. The grooves reduce the occurrence of fretting of the tube surface while a region of residual compressive stress formed in the tube proximate the bottom of each groove by the rolling process serves to counteract the stress concentration created by the grooves. In one embodiment a single groove formed in a thread pattern extends from above collet to within the area of contact. |
