Float collars designed by Digger are made from seamless casing grade steel and supplied with internal (non-returnable) valve which is tested and rated in compliance with API RP 10F standards. Float Collars are manufactured on latest CNC machines. The check-valve assembly fixed within the float collar prevents flow back of the cement slurry when pumping is stopped. Without a Floating Equipment, the cement slurry placed in the annulus could U-tube, or reverse flow back into the casing. The greater density of cement slurries than the displacement mud inside the casing causes the U-tube effect.
Available sizes 4 ½” to 20” and any special sizes can be custom made as required.
