Product Description
   API Spec Single Valve Casing Float Collars and Float Shoes
1. Description
The float shoe which is connected at the end of casing string functions as guide or back pressure valve. It is a kind of casing shoe which can produce buoyancy. With the advantages of high temperture resistance, good sealing feaure and easy connection, it can be used to replace guide shoe. It can be not only used in the unclassified technical casing, oil layer casing, but also in deep well, extra-deep well and special technology well.
2. Fetures
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;
Special non-rotational groove design ensures cementing plugs dilled out quickly;
It is economically priced.
3. Specifications
1) All inner parts are made of easily drillable aluminum alloy 
2) The device can be connected directly to same type casing 
3) Reliable back-pressure leak proof structure, enable grout or slurry flow with less resistance 
4) Valve seat and valve disk can effectively prevent grout from flowing back 
5) Hardness of base material is equivalent to API Spec N-80
>>The Auto Fill Cement Float Collar permits the casing to fill automatically while being run into the hole.
>>The valve is always in the open position allowing maximum filling of the casing as it is lowered into the well bore.
>>This is especially effective on liner jobs and sensitive hole conditions.
>>The circulation may be established at any time during or after casing is run.
>>The flapper type back pressure valve does not become operative until the drop ball is dropped or pumped down.
>>Like Differential Fill-up Equipment, the Collar is activated by the same ball.
>>From this point on, like Differential Fill-up Collar, this Auto Fill Cement Float Collar acts as conventional Floating Equipment.
>>All Auto Fill Cement Float Collars are PDC drillable.
Floating equipment is generally used in the lower section of the well to help:
Reduce strain on the derrick while guiding casing past ledges and slough zones in the hole;
Provide a landing point for bottom and top cementing plugs (pumped ahead of and behind the slurry as part of cementing operations);
Provide a backpressure valve to prevent cement from flowing back into the inner diameter of the casing after the cement has turned the corner into the annulus and the top plug has been bumped.
The float shoe contains a backpressure valve that prevents fluids from entering the casing while the pipe is lowered into the hole and prevents cement from flowing back into the casing after placement, while enabling circulation down through the casing.
