An outer tube is fitted onto the test tube at a predetermined interval and its end surface is aligned with the end surface position of the test tube, and a water-stop cover is provided on the outer tube and the end surface of the test tube,
An outer ring body with an outer flange into which the outer pipe can be fitted inside and an inner ring body with an inner flange into which the test pipe can fit outward are provided on the water stopper lid so as to project from the same axis. An annular outer flange body is provided, which is fitted onto the outer ring body and fastened to the outer flange of the outer ring body via an outer water sealing rubber to make the space between the outer ring body and the outer pipe watertight, and which is fitted inside the test tube. and an annular inner flange body that is fastened to the inner flange of the inner ring body via an inner water-stopping rubber to make the space between the inner ring body and the test tube watertight, and an external pressure chamber between the outer pipe and the test tube; and an apparatus for testing internal and external water pressure of a pipe body, characterized in that pressurized fluid can be supplied to each of the internal pressure chambers in the test pipe.
