CEMENT FLOAT VALVES – CKODU TYPE
They are designed for equipping the bottom of the casing strings made of pipes complying with GOST 632-80 so that to ensure continuous self-filing of the well casing with flushing fluid and prevention of reverse movement of the fluid (cement slurry) from the annulus space into the casing string during its cementing.
The use of the float valve enables run-in-hole of the casing string with installation of the ball above the valve seat or without the ball, which ensures self-filling of the string with flushing fluid.
They may be manufactured with short triangular connecting thread, with OTM and OTTG trapezoidal thread according to GOST632-80, and Buttress thread according to API specifications (API) and specifications of TATPROM-HOLDING LLC.
