Abstract RU 2278363 C2

FIELD: the invention refers to machine-building and to testing equipment and may be used in particular for providing work of tubes under pressure, and also at hydraulic tests of tubes on insulation for clamping of tubes joined to a hydraulic system.

SUBSTANCE: the clamping arrangement includes a body with two cradles located opposite to each other under the end sections of the tubes, two collet clamps with hydraulic drives. Each collet clamp consists of a cuff pressed with working liquid and at least one bushing. In the central part of the body there are also channels, the central one for feeding and withdrawal of working liquid and additional channels with periphery openings each connected with the central channel and the ring cavity of the cuff. In other two parts of detachable body there are regulated-fixed nuts with limiters of the working and the reversal movement of the elements of the collets' clamps.

EFFECT: increases exploitation qualities , reliability and longevity of the work of the clamping arrangement.
