For India and Iran Only
Hydraulically activated landing collar is used when running hydraulic set liner hangers or other hydraulic components run in a liner string. Shear setting of the assembly is field adjustable by the addition or removal of batch tested and matched shear screws. Internal components are constructed for wrought aluminum and are compatible for drill out. We retained ball seat design prevents the sheared out cage and ball assembly from interfering with float equipment run below the landing collar. Large, milled slots provide an unrestricted flow area while cementing. Shears/setting balls are available in bronze, aluminum or phenolic materials of varying specific gravity for use in vertical, high angle or horizontal wells or for specific cement weights. All seals are of standard HNBR material. A robust anti-rotation profile and latch assembly is designed to receive theliner wiper plug. When latched. These plugs provide a redundant seal to those of the float equipment. The body of the landing collar is manufactured of material matching the grade of the liner casing, which provides performance equal to or greater than that of the liner casing.
