NON-DESTRUCTIVE DEVICE X-ray inspection of circumferential welds of welded tubular elements

摘要

The invention relates to test and measurement equipment. The apparatus comprises an X-ray emitter collimator displacement system, X-ray detector, passing through the weld, and the display unit for converting the radiation to image the weld radiographic image. X-ray generator is a rod-shaped anode X-ray apparatus, intended for introduction into the cavity of the tubular element and of the X-ray collimator located in front of X-ray detector and configured as a disc with radially directed slits. The disc is rotatable about the longitudinal anode axis for passing through the X-ray slit toward the X-ray detector, the disc mounted on the hub cone shape, mounted on the anode to overlap the inlet opening of the tubular element when entering the anode into the cavity of the element, and the displacement system is arranged with the possibility of reciprocating movement of the anode in a horizontal direction and a vertical direction. 4 yl.
