The Design Department of LLC "DTF" has developed and launched a mass production of the device for extrusion of the core. This design is arranged such that when extraction of the core from core pipes it is necessary to carry out its rise, rests on the table of the drilling rig and freeing up safety toe, with the help of the hydraulic cylinder feed to produce the extrusion of the core without disturbing its structure. The operation is performed with the using of drill pipe and will allow you to simplify and reduce the time for extraction of the core from core pipes.
