CONCRETE COATED PIPES TESTING BENCH Russian patent published in 2018 - IPC G01N3/20 

FIELD: testing equipment.

SUBSTANCE: bench contains supports and hydraulic system for loading the testing pipe with a bend. The bench is equipped with the measuring system, containing 2n liquid indicators of changing the testing pipe position and n liquid indicators of the testing pipe movement, connected to the liquid supply line, where n stop cocks are installed in series. The testing pipe changing position indicators are connected hydraulically and mechanically in pairs, each of these indicators pairs are fixed at the testing pipe symmetrically about its axis and hydraulically communicated with one of the relevant indicators of the testing pipe displacement. The testing pipe is placed on two foundations and two jack supports, and the hydraulic system for loading the testing pipe with a bend includes the high-pressure pump and two pressure gauges. The high-pressure pump is connected through the pressure gauges in parallel to two jack supports.

EFFECT: design simplification, while improving the reliability of the test results, expanding the technical means range for testing the concrete coated pipes.
