Abstract

Shutter for fire pipes, which is especially designed to be used in the shutdown of petrolifer wells, essentially is characterized to be constituted from a pipe, of the same diameter that the pipeline affected, that for one of its extrems is removed in a nozzle tronco-conica that facilitates its coaxial coupling with the affected pitch tube, while in its other end incorporates a valve that is maintained initially open, having provided that on the above tube this also mounted a concrete tank, provided at higher level of the corresponding charge and vertically displaced with respect to the pipe, concrete tank that stay stabilized through pins relating to the trunk-conical nozzle to the lower tube extremity, so that the alignment of these pins causes the fall of the deposit and displacement of concrete mass, fresh, towards the coaxial confluence area entrela affected pipe and the new tube, sealing the coupling between these elements with his own hardening, after which the closing of the said v''alvula, with the consequent closure of the affected pipeline is feasible.
