Description of tubing Anchor:
The Type of tubing anchor catcher acts as a tubing anchor to maintain tension in the tubing string
and as a tubing catcher to prevent parted pipe from falling to the bottom of the well.
Tubing anchor catcher is run below a sucker-rod pump to anchor the lower end of the tubing string. Then the string can be landed in tension, reducing the tubing tendency to corkscrew from cyclical loading during pump operation.
Running & Setting of Tubing Anchor
1.Install the anchor in the tubing string, above or below the pump. Rotate the tubing to the left to set the anchor catcher
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.
Features:
• Rotate left to set, right to release
• Straight pull emergency shear release
• Increases pump efficiency
• Improves operating costs by reducing maintenance and
down time caused by tubing or sucker rod wear
• Parts interchangeable with other manufacturers
