Landing Collars and Float Equipment

Our landing collar provides a way of setting hydraulically actuated oil tools by using a ball that lands on a ball seat and also provides a profile for landing and bumping the wiper plugs at the end of displacement.

Description

The landing collar is installed in the pipe above the float equipment. The collar acts as stopper plate, and for this purpose it includes a seat and a locking mechanism. By this system, the pressure is maintained from above and below as soon as the wiper plug is landed and locked. The landing collar can also be equipped with a ball seat that is pinned to shear at approximately 1,000 psi above the pressure required to set the liner hanger. The float equipment prevents the uncured cement in the annulus from flowing back into the liner.
