Tube Expander

Tube Expander reduces a tube wall by compressing the outer diameter of the tube against a fixed container such as rolling tubes into ferrules, flanges, drums or tube sheets.

Hydraulic torque/Pneumatic rolling devices with an expander which consists of a case assembly with a thrust collar, mandrel, cage with rolls are used for expansion at the end of the tube to seals it against the tube sheet of the vessel.
