Tubing drain nipple

2025-07-10

Oil downhole tools tubing drain nipples are for oil well sucker rod pump. The drain nipple provides a positive method to equalize the fluid level in tubing strings without mechanical manipulation. When the pre-set point is reached, a set of shear pins will break and the external sleeve will move down to uncover the ports in the inside nipple.

The hydraulic tubing drain nipple utilizes rupture disc technology to provide accurate and reliable actuation of drain opening downhole. Hydraulic tubing drain has been used in many types of wells to eliminate the potential hazards associated with pulling wet tubing strings. Its design is simple and utilizes applied hydraulic pressure to open an engineered metal disc which creates a fluid drain port to the casing annulus without restriction.
