System for removing from a pipe fitting a plug for intercepting a fluid

摘要

A tool (1) and a plug (10) cooperating with each other in a system for removing the plug from a pipe fitting (50) are described. The system comprises a plug (10) provided with at least one deformable body (11) and at least one respective supporting body (14) comprising a first threaded portion (12) that is suitable to cooperate with at least one threaded portion (51) of the pipe fitting (50) in which it is installed, and at least one second threaded portion (13) having its screwing direction opposite to the screwing direction of the first threaded portion (12). The system also comprises a tool (1) provided with a main body (2) to which an operating shaft (3) is coupled, the latter being axially translatable and rotatable with respect to the main body, the operating shaft being also provided with means (3b) for its setting in rotation and/or translation. The operating shaft (3) comprises at least one threaded portion (4) that has the same screwing direction of the second threaded portion (13) of the plug (10) and that is suitable to cooperate with the second threaded portion (13) of the plug (10).
