PEENING DEVICE FOR PEENING WELDS INSIDE STEEL SUBMARINE PIPES, PROCESS FOR PRODUCING STEEL SUBMARINE PIPES USING SUCH A DEVICE

摘要

The present invention relates to a method of implementation of the undersea pipes (1) made of steel, comprising the assembly by welding the ends of elements of a unitary pipe (2a - 2b), the weld beads being disposed outside the pipe, characterized in that it performs a hammering located inside the pipe at the level of the welds (6) and on either side of the welds (6), so as to create a corridor (7) to be hammered surface. The hammering is performed by creating a plurality of impacts, with at least one tool for hammering (5) comprising a single hammer (51) is displaced in reciprocating translational movement against the surface to be hammered said tool for hammering being moved in rotation and / or longitudinal translation inside the pipe with a device comprising a wheeled carriage (3).
