Typical Applications:

• Tubing drains remove the hazard of handling stuck pumps, by pulling dry strings
• When tubing cannot be rotated or pulled to actuate mechanical draining devices
• Where corrosion builds up restricts the "S" drain from operating properly
• Provides a means to pump down the tubing to kill a gassy well before pulling
• Eliminates expenses and wasted time associated with wet jobs
• Oversized tubing pumps that do not have drain valves operating or none at all
• Allows producer to double traveling, and standing, valves, and still pull dry strings
• Drains tubing for submersible pumps equipped with a check valve and pumps in a high angle or straight hole
• Drains tubing above anchors and packers

Operation:

The Fike HTD is simple in design and utilizes applied hydraulic pressure to rupture the membrane which opens the fluid port to the casing annulus, with no restrictions. The Fike HTD should be installed box up and pin down at the desired depth in the tubing string. For hydrostatic head at the drain, and determination of the proper disc pressure (psi), multiply .433 psi/ft by the drain depth. Then select the disc with an additional 2,000 psi above the nominal fluid load.

(Note:Disc selection is calculated from pressure differential. Contact Fike or your local Sales Representative for further assistance.)

Service:

The Fike HTD is best serviced by your local distributor to ensure proper disc preparation, assembly and testing. In applications where this is not possible, the Fike HTD can be field serviced, with moderate care, and attention to detail.
