API TAC type Drag Block Mechanical Tubing Anchor for oil field
Anchor the tubing string in tension or compression in wells of any depth.
This prevents movement of the tubing string during pumping operation, thus increasing pump efficiency and decreasing rod wear.
It has a tension shear release that is easily adjustable in the field.
Working Principle
1.At the desired setting depth, rotate the tubing to the left with hand wrenches
until the slips contact the casing
2.With tubing in slight compression, rotate the tubing to the right to retract the cones from the slips and allow the slips to move back into the housing.
1.Rotate left to set, right to release
2.Straight pull emergency shear release
3.Increases pump efficiency
4.Improves operating costs by reducing maintenance
