Description:
Float collar's installed on the casing and up the float shoe. It also like float shoe to provide buoyancy to the casing string while it lowered, reducing the load on the Drilling rig. A build in check valve provides buoyancy to the casing string also prevents cement from re-entering the casing after it is displaced. It's a receptacle to cement plug.
A few advantages of the Float Collar provided by our company are:
High strength design ensures high pressure bump and back flow resistance;
Withstands long periods of circulation;
Automatic fill-up, saves considerable running-in time of casing;
Easy drill out with PDC bits;
Special non-rotational groove design ensures cementing plugs dilled out quickly;
It is economically priced.
