Non-Rotating float Collar

Product No.:



Non-Rotating Float collars designed by Digger are made from seamless casing grade steel and supplied with internal check valve with anti-rotation mechanism on the top that improves drill-out performance which is tested and rated in compliance with API RP 10F standards. Traceability of the component material starts from the mill material certificates and collars are processed on CNC machines. The check-valve assembly fixed within the float collar prevents flow back of the cement slurry when pumping is stopped.
