CE CT Hydraulic Knuckle Joint
The CE CT Hydraulic Knuckle Joint enables a controlled mechanical deviation of up to 15° to be applied to the BHA. It is commonly run as part of the DTI Multi-Lateral Entry System, the Hydraulic Knuckle Joint can also be used to angle the BHA for cleaning operations or for jetting tunnelling applications.
The Hydraulic Knuckle Joint is held in the straight position by high load spring actions. As the tool string pressure increases, the knuckle joint articulates and becomes rigidly inclined at a maximum 15° position. An optional bleed port indicator provides a clear pressure signal to the operator indicating that the joint is fully articulated.
