The ПХН cementless liner hanger
The ПХН cementless liner hanger is designed for fixing wells with casing liner without cementing and is available in three designs which differ in the method of overlapping the internal space: – using throttle-shut-off valve by increasing the washing performance; -by starting the cementing plug and pumping it before landing in a special stop- seat – by starting the ball and pumping it before landing in the seat of the liner hanger.
The ПХН liner hangers are equipped with a FIA unit (filter isolation unit) and allow washing through a casing shoe.
