The utility model relates to a hydraulic test device for nuclear power main steam super pipeline nozzles. A tooling pipe is covered outside a nuclear power main steam super pipeline and pressed by bolts II, plugs and copper gaskets at the nozzles of the nuclear power main steam super pipeline are pressed by four external pressing bolts III and four internal pulling bolts I, the external pressing bolts III and the internal pulling bolts I are distributed in square, and the included angle between each external pressing bolt III and each internal pulling bolt I is 45 degrees. During hydraulic test, the copper gaskets are pulled inwards and the plugs are tightened through the four internal pulling bolts I, and the copper gaskets are pressed by the four external pressing bolts III inside the main steam super pipeline. By means of external pressing and internal pulling, the sealing copper gaskets deform to realize sealing effect. In addition, the nozzles of the nuclear power main steam super pipeline can be sealed
