Bypass Ball Seat Slide Sleeve

Bypass Ball Seat Slide Sleeve


The by-pass ball seat is always used together with hydraulic packer for setting, also used on the bridge plug to release the fluid in tubing before pull out of the hole. When it’s used with hydraulic packer, the box need to be connected below the packer, when comes to the designed depth, when setting completed, the tubing pressure build up the designed pressure, then the pin will be sheared off, the ball and slide sleeve will move down and block off the string, thus realizing the connection of tubing and annulus.

This Model is drifted with the corresponding API tubing drift size.

NOTE: Additional size, weight, end connection etc. are also available on request.
