NODE sensors for diagnostics of technical condition of underground pipelines

摘要

abstract; Sensor unit for diagnosing the technical condition of underground pipelines; The proposed utility model relates to devices for noncontact diagnostics of technical state shell side ferromagnetic subterranean oil and gas pipes. The proposal is particularly effective in the diagnosis field and transport pipes of small and medium diameter (100-500 mm) as well as the inspection of steel and cast iron steel structures.; The technical result of the utility model is to increase the accuracy of fixing defects and stress concentration zones in commercial and transport pipes of small diameter, increase in the accuracy of measurement results of binding to the position of the pipeline, as well as improving the reliability and precision of separation defect fields and interference fields.; Technical result is achieved due to the fact that the sensor unit for diagnosing the technical condition of underground pipelines, comprising three component sensors constant magnetic field coupled mountings of non-magnetic nonconductive material, according to the utility model is a three-dimensional shape as a cube whose vertices are located three component sensors permanent magnetic field coupled along the edges of the cube fasteners nonmagnetic nonconductive material, the ternary d The sensors of the constant magnetic field are configured such that in each pair of sensors located at the ends of each of the edges of the cube, the same name and coaxial with the axis of the rib line - coaxial with each other and the same name sensor axis orthogonal lines edges - are parallel to each other along a vertical axis cube symmetry on its upper face and on the underside has three-component sensors according to one of the alternating magnetic field, which are interconnected by a nonconductive nonmagnetic material for fastening the depth registration capabilities servation pipeline., Sensors and DC and AC field coupled holders of a nonmagnetic and nonconductive material.
