Product Description

Float Shoe and Float Collar Used for Casing Pipe

Applications:
Float collar is installed on the casing and up the float shoe. Like float shoe, it provide buoyancy to the casing string when it's 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's displaced. It's receptacle to cement plug.

Features:
1. All inner parts are made of easily drillable aluminum alloy.
2. The device can be connected directly to the casing of the same type.
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. Non-rotating landing plate is available on request.
6. Either PDC or rock bit drillable.

The Float Collar is run in a casing assembly, usually several joints above the Float Shoe. It serves as an extra back pressure valve sealing against pressures from blow while running the assembly and after the cementing job. Internal latch and valve are readily drillable. Its capability of back-pressure is over 25MPa.

The ZS float shoe also has a back-pressure valve to prevent back flow. It permits cement to run through side ports when the nose of the shoe is on the bottom. Inner valve and bottom guides are all made of drillable material. Its capability of back-pressure is over 25MPa.
