• Landing Collar and Float Equipment

    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, pinned to shear at approximately 1,000 psi above the pressure required to set the liner hanger. The Float Equipment has the important function to prevent the uncured cement in the annulus from flowing back into the liner.
