float shoe for casing

 

1. Describtion

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
