摘要

Mechanism used in Pressurized Pipelines for the identification of wear on the inner surface.It is described a mechanism applied in pipe pressurized for identification of wear on the inner surface which has a ring structure (20) positioned between the casing (11) and the surface exrterna pressurized duct (10), said ring structure (20) with the intern The leaked with apertures (201), and an outlet provided with a connection (21).Performing at the free end of the connection (21), a duct (22) which has a pair of bases (30) interval by a spring (not represented) and at the opposite end to the disposal of the bases (30) an inflatable structure (33) which receives pressurized air from the chamber of the ring structure (20), sinaliz I 'm the leak.When the inner surface of the pipe (10) or coating (11) of the shaft (10) decreases its thickness, the material flow that moves in the region inside the duct (10) promotes its rupture, causing a flow of pressurized air to the pressure equivalent to the inner part of the pipe (10).In this situation, the bases (30), who were united by virtue of the air pressure, moving through the spring force present between said base (30), driven by the breaking of the ring (20), indicating to the operator the damage on the surface of the duct (10).
