ULTRASONIC DEFECTOSCOPE SENSOR CARRIER

The invention relates to devices for monitoring the integrity of main oil pipelines by means of passing an ultrasonic defectoscope, having ultrasonic sensors installed thereon, through a pipeline. An ultrasonic defectoscope sensor carrier consists of at least one section. The section is comprised of a central shaft, on which a polyurethane head cone, a tail cone and a set of rings having ultrasonic sensors positioned thereon are installed between a head fork and a tail fork. Centering sleeves are installed in the head portion and in the tail portion of the ultrasonic defectoscope sensor carrier. The claimed ultrasonic defectoscope sensor carrier is comprised of at least one section. In order to allow for the ultrasonic defectoscope to pass through small-radius turns in a pipeline, the ultrasonic defectoscope sensor carrier can be comprised of two sections which are hingedly connected to one another by means of a Cardan joint. The ultrasonic defectoscope sensor carrier is comprised of standardized and interchangeable parts and assemblies, which allow for changing the length and number of sections of the sensor carrier in accordance with operating conditions. Un portador de sensor detector de defectos ultrasónico/por ultrasonido que consta de al menos una sección, esta sección comprende una barra central con una horquilla de cabeza y una horquilla de cola dispuestas en la misma. Collares de centrado están unidos a las bridas de horquillas de cabeza y cola, y un cono de cabeza de poliuretano, un cono de cola de poliuretano y un conjunto de anillo están dispuestos entre los collares de centrado. El conjunto de anillos es un cilindro con un agujero central y ranuras helicoidales en la superficie cilíndrica exterior. Los sensores ultrasónicos están dispuestos en las ranuras helicoidales y se fijan por tapas, por medio de tornillos. El diámetro exterior del portador del sensor detector de defectos ultrasónico tiene un valor que no es mayor que un estrechamiento máximo admisible de una tubería.
