RTTS safety joint is mainly composed of upper joint, J groove sleeve, mandrel, valve body, lower joint and other parts. To release the safety joint, a pull is first applied to the string to break the pull sleeve. This does not, however, release the safety joint; it is necessary to move the string up and down and maintain torque to release the safety joint.
The RTTS multi-function safety connector can be screwed on the RTTS circulating valve or used between the RTTS circulating valve and the RTTS packer. When the safety connector is screwed on the upper end of the RTTS circulating valve, it can be screwed directly into the upper end of the circulating valve.
