| 摘要 |
The present invention relates to an arc block of a pipe press tool, which prevents damage to a pipe by forming grooves and protrusions on both ends of multiple arch blocks formed on the inner side of a press tool for pressing the outer surface of a large-diameter pipe into which a small-diameter pipe is inserted; forming pressed corrugations corresponding to the grooves and protrusions of the arch blocks on the inner surface of the pipe; and dispersing the pressure applied to the pressed corrugations using high-pressure fluid and air flowing in the pipe. The arch block of the pipe press tool according to an embodiment of the present invention is divided into multiple parts on the inner side of the pipe press tool and directly presses the outer surface of the pipe. The grooves and protrusions engaged with each other are formed on the ends of the arch blocks adjacent to each other. |
