Hydraulic disconnector
Hydraulic disconnector is designed for running and fastening of casing "liner". This disconnector design allows you to rotate and axial move the liner string by an acceptable value. The PL-HRTRH disconnector is used for both vertical and directional wells. Is used with various technological equipment mainly together with hungers, and "stop" assemblies with a low weight of the casing "liner". Disconnection the running tool after all technological operations is carried out by by creating a predetermined value of activation pressure. In case of failure to achieve tightness, the left cross-over is turned away by rotating the drilling string to the right.
