Abstract

Improved device to make derivations in pipes, coupled to a collar as a clamp, provided with an outlet and fixed in the pipe with the interposition of an O-ring sealing between both that surrounds the mouth and the point of the perforating pipe, characterized in that it consists of a tubular body comprising a connection end provided with coupling means to the exit mouth of the collar and of a seat, at least one side bypass, to which the bypass pipe is connected, and the other opposite end of closure, to which a bushing provided with a flange applied against said end is coupled with the interposition of a joint and of an internally threaded section, a main cable gland being applied against the free end of the bushing, through from which axially threaded with respect to the bushing, a tubular rod externally threaded and provided at its inner end ac holder of a sealing element in correspondence with the seat of the connection end of the tubular body, inside which a perforating element moves freely, the appropriate sealing joints between both being provided and a secondary press-tow at the end of the tubular stem, so that said piercing element is displaceable between an active position against the main tube, keeping the shutter of the rod against the seat applied, in which said element is acted with a conventional tool to pierce said tube, while the same circulates the fluid at full pressure, and since the entrance to the tubular body is kept closed by the obturator, the desired shunts can be connected, and an inactive position withdrawn from the hole made and in which the obturator of the shank is also separated from the seat, in which position the piercing element is maintained by a through pin through said element or and the tubular stem, joining them.
