api 5ct float collar
1. Descriptions:
Float collar and float shoe are essential conventional accessories for substructure of casing string. The float shoe or float collar is a kind of casing shoe or coupling which can produce buoyancy. With advantages of high temperature resistance, good sealing feature and east connection, the float shoe and float collar can be not only used in unclassified technical casing, oil layer casing but also in deep well, extra-deep well and special technology well.
2. Features:
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
