COLLAPSIBLE CONTAINER FOR DEVICE FORMING SAMPLES FROM CEMENT SLURRIES FOR STRENGTH TESTS Russian patent published in 2019 - IPC G01N1/31 

FIELD: technological processes.

SUBSTANCE: invention relates to container of device designed to form samples from cement slurries used in the cementing of oil and gas wells, obtained under conditions simulating borehole temperature and pressure, for subsequent strength tests of samples for bending and compression. Collapsible container for the device forming samples from cement slurries for strength tests consists of the outer walls, provided with holes for fasteners for fixing, the bottoms and the lid with a handle fixed on the lid for installing and removing the container. Bottom surface of the cover is made with through slots and additionally contains a cruciform partition. Partition is made to the height of the internal cavity of the device and divides the container cavity into four cavities of square section. Partition is fixed with its ends in grooves made from the inside in the middle of each outer wall of the device. Cross shaped partition can be made detachable or welded.

EFFECT: invention provides a reduction in molding time, ensuring the accuracy of the test results and the ease of manufacture and maintenance of the device.
