ABSTRACT:
A boiler tube rupture testing apparatus and method in which two segments are inserted into a tube section which sections together form a disc having a outer diameter slightly less than the inner diameter of the tube section. A creep rupture machine is connected to the individual segments for exerting to oppositely directed forces on the segments, respectively. The forces can be selected to simulate the hoop stress applied to the tube section due to internal pressure and can be maintained on the tube section until rupture occurs which will lead to as accurate estimation of the life of the tube.
