Abstract: The present invention relates to the technical field of equipment for impact tests; more specifically, to an instrumented pendulum for Charpy-type impact tests on miniaturized samples. The instrumented pendulum (1) for miniaturized Charpy impact test, according to the present invention, is characterized in that it comprises a main monolithic part, a cleaver (7) housed in an anterior opening of the main monolithic part, and the at least two additional plates (11, 12) removably attached to the respective sides of the main monolithic part of the instrumented pendulum (1). Further, the present invention relates to a Charpy impact machine comprising the instrumented pendulum (1) and an automatic device (6) for releasing the instrumented pendulum (1) at different values of firing angle.

Abstract: The present model refers to a bolted and welded clamp-type repair with bolts and nuts housed in recessed locations that will be hermetically insulated by welding plugging discs to be used in the repair and maintenance of pipes. The clamp-type repair comprises a lower part (1) and an upper part (2) that will perfectly accommodate the pipe, wherein said lower part (1) and upper part (2) each comprise a flanged portion (3) at both ends, and the flanged portions (3) each comprise at least one recess (4) to accommodate the bolt-nut assembly (7) where the plugging discs (8) will be positioned immediately above. The welding process of the edges between the same and next to the pipe (12) and the plugging discs (8) next to the surface of the flanges (3) guarantee the necessary safety and enable the repair to be defined as permanent, without the need for later replacement.

Abstract: Pipelines with a control system and forced circulation of fluids through the annulus between an inner barrier and an outer cover of a pipe use a system configured to force circulation of fluids through the annulus. The pipe includes segments (T1, T2, T3, TN) joined together by means of connectors, wherein each segment of the pipe has an injector pipe (I1, I2, I3, IN) for injecting fluid into the annulus at a first end of the segment, and a return pipe (R1, R2, R3, RN) for removing fluid from the annulus at a second end of the segment.

Abstract: A flexible pipe connector for effecting control and forced circulation of corrosion-inhibiting fluids through an annulus between inner and outer sheaths of a flexible pipe having multiple connected segments includes an attachment mechanism for connecting to an end of a segment of flexible pipe and at least two distributing rings for distributing corrosion-inhibiting fluid. The rings are configured to be positioned in the annulus of the flexible pipe, wherein at least one distributing ring has fluidic access to the annulus of the flexible pipe. This distributing ring is configured to be connected fluidically to at least one distributing ring, in an adjacent connector, that does not have fluidic access to the annulus, A distributing ring that does not have fluidic access to the annulus of the flexible pipe is configured to be connected fluidically to at least one distributing ring, in an adjacent connector, that comprises fluidic access to the annulus.

Abstract: A pipe is used for control and forced circulation of corrosion-inhibiting fluids in an annulus thereof, the annulus located between an inner pressure barrier and an outer cover of the pipe and containing a number of layers. The pipe includes two layers of tensile armor within the annulus; at least one injection pipe laid helicoidally on the longitudinal extension of the pipe; at least one return pipe laid helicoidally on the longitudinal extension of the pipe; and a ventilation layer within the annulus, the ventilation layer being configured to facilitate the flow of fluids longitudinally through the annulus of the pipe.

Abstract: The present invention provides a device for removing internal blockage materials (10) from a fluid-conveying line (3), said device comprising a cutting tool (9) activated by a rotary actuator (8), in which: the cutting tool (9) is positioned at the front of the device; and the cutting tool (9) comprises a diameter that is smaller than the internal diameter of the fluid-conveying line (3).
