Hydraulic Landing Collar

Hydraulic Landing Collar – SF-52


Stammford’s Hydraulic Landing Collar is used to provide a way of setting hydraulically actuated oil tools by using a ball, which lands on a ball seat. They also provide a profile for landing and bumping the wiper plugs at the end (after displacement).Landing collar inserts have a profile to latch the wiper plugs in place to prevent them from rotating , locking or sealing during the process of drilling them out. For highly deviated or horizontal applications, the ball seat can be manufactured with a special profile to guide the ball seat. They are normally placed one or two joints above the nearest float collar.
