METHOD FOR PIPES TESTING Russian patent published in 2008 - IPC G01M3/08 

FIELD: technological processes; measurement.

SUBSTANCE: invention is related to the sphere of testing equipment and may be used for testing of pipes, pipelines and their connecting devices and joints for strength and leak-tightness. Device contains frame, which has in its ends the support fingers, on which from one side of frame there is a carriage installed with movable detachable plug, and on the other side there is immovable detachable plug. Carriage has the possibility of longitudinal movement in relation to frame with the help of hydraulic cylinder, which is installed in the carriage from the frame external side during tension testing of pipe or from the internal side of frame during pipe compression test. Every plug has a sealing element and is made in the form of counter end part of tested pipe and creates with the end part of this pipe the connecting device, which is equipped with stop element, which prevents the axial displacement of plugs and tested pipe. Connecting device may be made in the form of faucet joint with stop ring or in the form of flange joint with annular clamp of bow type as stop element. One of the plugs is connected with system for creation of testing pressure.

EFFECT: increase of testing axial loads and simplification of pipe testing design device.
