Tool for the fluid-tight closure of test presses for tubes

摘要

This tool comprises a casing fitted with an expandable ring composed of segments 14 used as an axial support for the tube 2. The segments 14 can be tightened against the tube by an elastic fluid-tight joint 16 and they can be spaced apart from the tube by a ring 31 which slides axially and which is fitted with a wedge profile capable of acting on the wedge-shaped ramps formed on the segments 14. <IMAGE>
