An apparatus for testing a tube for its strength to resist internal pressure, is disclosed of: an expandable elastomer having a hollow body with one open end; a test head, connected to the expandable elastomer, to provide the expandable elastomer with pressure using fluid as a medium; a holder, disposed below the test head, to vertically move a tube into a place in which the expandable elastomer is inserted into a tube; and a transferring mechanism, arranged beside the holder, to provide the holder with a tube from a rack. The apparatus according to the present invention can automatically and continuously test numerous tubes for its strength to resist internal pressure, overcoming disadvantages of the non-automatic, non-continuous apparatus previously disclosed.
