I. Purpose

Self-propelled flash x-ray apparatus SIRENA-5 is designed for testing of the welds of oil and gas pipelines by panoramic method of the x-ray photography.

II. Advantages

The main difference of the SIRENA system from its Russian and foreign analogues is the absence of the isotope master-controller, which can be dangerous for the operator.

All the commands to move inside the tube, to stop, or switch on x-rays are specified by the standard portable x-ray apparatus ARINA-1, positioned on the outside surface of the tube and controlled by the remote-control unit.

In the SIRENA unit the standard x-ray apparatus ARINA-3, ARINA-5 (or ARINA-1 only for SIRENA-6)  is used as a panoramic radiator for x-raying of the circular welds. It is placed on the self-propelled carriage supplied with the dc engine and two accumulators. The electronic unit fixed on the special rod of the carriage receives the commands from the ARINA-1 apparatus and controls the carriage.

The master-controller ARINA-1 and the main apparatus ARINA can be used as a part of SIRENA crawler, or independently, for x-raying of the tubes through two walls.
