Float Collar
The Float Collar is run in a casing assembly, usually several joints above the float shoe. It serves as an extra back pressure valve sealing against pressures from blow while running the assembly and after the cementing job. Internal latch and valve are readily drill-able. Its capability of back-pressure is over 25 MPA.
