INNER STRING FLOAT EQUIPMENT

Overview

Top-Co’s inner string cementing float equipment allows large diameter casing strings to be cemented through the drill pipe or tubing by stabbing/latching and sealing into the float shoe or collar. This eliminates the drill out of large quantities of cement, reduces circulating times, and reduces pumping pressures. Top-Co’s inner string cementing float equipment utilizes the HFX® valve and is offered with or without a latch-in feature on the stinger.
