Tubing Drain

TUBING DRAIN The Tubing Drain ( TD) provides a positive method to equalize the fluid level in tubing strings without mechanical manipulation. The TD utilizes rupture disc technology to provide accurate and reliable actuation of drain openings downhole. The rupture disc assembly contains a 7/ 8” opening area. Appropriate production practices include the TD as standard equipment in all wells to eliminate the potential hazards associated with pulling wet tubing strings.The TD 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 TD should be installed box up and pin down at the desired depth in the tubing string. It is important to correctly calculate the required burst pressure and select the correct TD rupture disc for the application.
