HSC-A Hydraulic Stage Tool
The HSC-A hydraulic stage tool features inner closing structure, opening through pressure difference. The closing plug drives the closing sleeve down and then shut circulation ports.
Features:
-
Opening pressure can be adjusted and it’s not subjective to hole angle or mud properties for operation
-
The pressure-relief design prevents fluid trapping and compression during the closing phase of the tool’s operation
-
The I.D. of upper / lower sub is the same as that of casing, but smaller than that of closing sleeve, which can minimize chances of damages to the closing sleeve.
-
The inner seats are made of an easily drill-able nitrile rubber / aluminum material. Both the opening and closing seats lock against rotation for easy drill-out.
