Washover Safety Joint |
| The Gotco Washover Safety Joint is manufactured to provide safe and easy release and make-up whenever disengagement from the washover string becomes necessary. This dependable, field tough tool is designed to transmit torque in either direction when placed in the washover string. |
Construction |
| The Gotco Washover Safety Joint consist of a pin section, a box section, and a friction ring. the internal connection of the safety joint is a coarse acme thread used to facilitate easy pack-off and re-engagement. A knurled release ring between the box and pin sections maintains torsion integrity until back off procedure is initiated. An O-ring seal contains pressure while the safety joint is made up. |
Assembly |
| To assemble, install the safety joint in the drill string and make up the service connection to a torque of approximately 60 to 75% of the string connections. In washover strings, the safety joint should be located between the drill pipe and the washover pipe. Gotco Washover Safety Joints are provided with a tool joint box thread up and a washover pipe pin thread down. To disengage the safety joint while down-hole, place pipe in tension and apply left-hand torque. Hold torque while slowly lowering pipe until safety joint breaks. Continue to unscrew safety joint to the left. To re-engage the safety joint, lower pipe until pin section of safety joint lands on box section. Apply one point of weight. Rotate to the left one or two turns. Then rotate to the right until torque builds up, indicating safety joint is made up. |
