Drill Pipe Safety Joints by Logan Oil Tools, Drill Pipe Safety Joint is designed for the safe and dependable release from drilling, fishing, tubing, washover, or testing strings should they become stuck. The simple design of the Logan Drill Pipe Safety Joint has no release ring, which allows for quick disengagement procedures of the tool.The Logan Drill Pipe Safety Joint comes in a variety of popular sizes for drill pipe strings. Logan will also design and manufacture safety joints to meet a customer’s specific need. The Logan Drill Pipe Safety Joint is made up of a box section and a pin section. Each Safety Joint is designed to withstand internal and external pressures through the use of o-ring seals above and below the threads. The O.D. and the I.D. of the Logan Drill Pipe Safety Joint match the standard O.D. and I.D. of the tool joint connection that is requested.
Operation
The coarse thread design of the Logan Drill Pipe Safety Joint is resistant to wedging or loosening of the tool during operation. The Safety Joint’s design allows for tthe transmission of torque in the left-hand or right-hand direction.
To Disengage the Safety Joint in the Hole
1. Pick up on the drill string until 500 to 1,000 lbs. remains on the Safety Joint. If too much weight is left sitting on the Safety Joint, there is a possibility that damage could occur to the shoulder of the box section when the tool disengages.
2. Rotate the string to the left until 40% of the tool’s right-hand make-up torque is applied.
3. Pick up on the string slowly while rotaing to the left to unscrew the Safety Joint. The coarse threads will lift the pipe approximately 1/2" to 1-1/2" (depending on the size of the Safety Joint) for each revolution of the string.
4. Care should be taken to keep a little weight on the Safety Joint as the tool is unscrewed as recommended in Step 1. The operator will be able to see a weight decrease as the Safety Joint separates.
To Reengage the Safety Joint in the Hole
1. Lower the string into the hole until the Pin Section contacts the Box Section.
2. Apply approximately 1,000 lbs. of weight and rotate the string slowly to the right. An increase in torque will indicate that the Safety Joint has reengaged.
