    A pipe tester has sections (1, 2) comprising a rotary roller mechanism 42 for rotating a pair of pipes (4) under test. An inner test unit 7, Fig. 2 is movable longitudinally in each pipe between parking stations 9, 10, at the ends of the test sections and an outer test unit 12 is movable on a trolley 45 along the outer surface of the pipe. Pipes to be tested are introduced laterally to and removed from the test section by conveying devices 13, 14, 15. The inner test unit comprises a cylindrical housing carrying contactless test devices and provided with front and rear chassis each having a drive roller and two supporting rollers which are angled relative to the longitudinal axis of the pipe and engage the inner surface of the pipe so that the inner test unit is driven through the pipe by the rotation of the pipe. <IMAGE>

    X) The invention relates to non-destructive testing of products in the metallurgical industry and can be used to control the quality of pipes. A device for sorting pipes, comprising external and internal control units and a mechanism associated with them for moving a pipe relative to said nodes l, is known. However, the performance of the control unit with this device is insufficient, since when the dimensions of the pipes are changed, additional time is required to retool control units. The closest to the invention to the technical essence is a device for non-destructive testing of pipes for the presence of cracks, containing at least one roller conveyor, an external and internal control carriage with roller supports interacting with it and contactless sensors 2 installed on them. However, the range of standard sizes of condruled pipes in a known device is limited because the internal control carriage is made in the form of two magnetically connected nodes. The interaction force between these nodes is sufficient for the carriage to function only up to a certain value of the wall thickness of the pipe being monitored. The aim of the invention is to expand the range of dimensions of the products being monitored. The goal is that the device for non-destructive testing of pipes for the presence of cracks one roller table, external and internal control carriages interacting with it with roller bearings and contactless sensors mounted on them, internal control carriage Completed in the form of a cylindrical body mounted on its ends of three-link assemblies, on the ends of which roller bearings are fixed, some of which are leading, and all are mounted with the possibility of changing the angle and distance between their axes of rotation and the longitudinal axis of the body. In Fig. 1 shows a device for non-destructive testing of pipes for the presence of cracks, the general view in Fig. 2 is the internal control carriage, side view, and Fig. 3 is an end view of the carriage for internal control. The device contains a conveyor 1, which receives a controlled pipe 2, an external control carriage 3-5, an internal control carriage 6, contactless sensors 7 combined with a signal-processing unit with autonomous power supply (not shown), three-unit units 8 and 9 for moving internal control carriages, drive 10 for preliminary feeding of carriage 6 to test pipe 2, hydraulic cylinders 11 and 12 for orientation of the longitudinal axis of the carriage 6 relative to the longitudinal axis of the pipe 2. Internal control carriage 6 is made in the form of cylindrical The second housing 13, at the ends of which three-link assemblies are mounted, at the ends of which roller supports 14-19 are fixed, are supports 16 and 19. The distance between the axes of these supports and the longitudinal axis of the carriage b, as well as the angles between these axes rigidly fixed. The distances between the axes of the remaining roller bearings 14-18 and the longitudinal axis of the carriage, as well as the angles between these axes, are adjusted in accordance with the size of the pipe 2 being monitored. Thus, the working gap between the contactless sensors 7 and the inner surface of the pipe 2 is stable when changing its standard sizes. The device works as follows. The controlled tube, having previously received rotational motion on a transport roller table (not shown), enters the roller table 1 and continues to rotate by inertia. The internal control carriage b is driven by the actuator 10 into the cavity of the pipe 2 and then continues to move along its axis, the speed of which is determined by the values of the angles between the axes of the leading roller bearings 14-19 and the longitudinal axis of the carriage body 13 b. Synchronously with the movement of the latter, the carriages 3-5 of the external control move. As a rule, control devices (not shown) are installed on carriage 4, and marking devices (not shown) are installed on carriages 3 and 5. Thus, scanning of pipe 2 is carried out along screw paths. Signals about the results of the control come from carriages to the corresponding indicators (not shown) depending on the means of control installed on these carriages. The use of the proposed device for non-destructive testing of pipes allows expanding the range of sizes of pipes to be tested several times due to the fact that the distances of the roller bearings from the axis of the inner control carriage 1 are controlled depending on the diameter of the pipe being tested.
