DEVICE TO REMOTELY REVEAL PRESSURE PIPELINE FAULTY INSULATION AND WALLS Russian patent published in 2009 - IPC G01L7/00

Abstract RU 2356019 C2

FIELD: physics, measurements.

SUBSTANCE: invention relates to pulsed hardware intended for gaining information about parasitic emissions in lines with uniformly distributed parametres and can be used to reveal the pressure pipeline insulation and walls with the help of acoustic waves and E₀₀-type electromagnetic sounding waves. The proposed device differs from known ones in that the pressure emergent drop alarm incorporates electromagnetic reflectors of the E₀₀-type surface waves arranged on opposite ends of pipeline under control and a reflectometre with wire-counter balance connected with the pipeline wall controlled part. Note here that aforesaid insulated wire-counter balance is arranged perpendicular to the pressure pipeline wall in the ground plane, the reflectometre casing being isolated from the ground. Since the said reflectometre records the waves propagating both inside the pressure pipeline (hydraulic shock wave) and on over its surface (E₀₀-type surface electromagnetic wave).

EFFECT: efficiency and accuracy of revealing pressure pipeline insulation and wall faults are increased.
