The Wellpro Group Hydraulic Disconnect is an extremely robust torque through drop ball disconnect. The disconnect can handle straight pull, impact, jarring and torque loads without affecting the release mechanism.
The disconnect facility provides a means of disconnecting by simply dropping a ball from surface and applying pressure. After disconnection a standard internal GS profile allows for subsequent retrieval.
The circulating sub is ball activated and, when utilised, introduces a flow path from the tool ID to the annulus thus allowing for higher circulation rates. If, for any reason, circulation through the tool string is lost, a rupture disc option is also included as standard. This can be set and ruptured at a predetermined pressure.
