Float Shoe and Float Collar for Well Cementing
The round nose guides the casing away from ledges and obstructions in the well bores as the casing is lowered. A build-in check valve provides buoyancy to the casing string also prevents cement from re-entering the casing after it is displaced.
Qualified concreting procedure.
The valve is capable of withstanding long periods of circulation.
Either PDC or rock bit drillable.
