Zusammenfassung:	The utility model discloses a pipe end sealing device for pressure testing relates to the sealing device field. This pipe end sealing device for pressure testing arranges in in the pipe, sealing device presses the pipe including being arranged in letting in to the pipe leading to of compressed gas or liquid, lead to and press the pipe box to be equipped with clamp plate group, elastic ring and extrusion mechanism, clamp plate group is including two at least clamp plates, the elastic ring is located between two adjacent clamp plates, extrusion mechanism organizes the diameter of increase elastic ring through the extrusion clamp plate, the elastic ring is hugged closely the inner wall of pipe is realized sealedly, the elastic ring adopts elastic material to make. The utility model provides a problem of the sealed convenient and extravagant material inadequately of pipe end during pressure testing in the past.
