Tubing Drain
Description
The Tubing Drain provides a means of draining or circulating through tubing when pulling out of the hole where the tubing is unable to drain or be circulated normally. To open the drain ports pressure is applied to the tubing which will shear the shear pins in the shifting sleeve and open the Tubing Drain Sub. The amount of pressure required to open the drain ports is easily field adjustable.
NOTE: Once the drain ports have been opened they will remain open until serviced on surface.
