Float Collar Float Shoe for Pipe

Product Description

Float collar Float shoe Float collar Float shoe are mounted on the middle and end parts of casing string, the main purpose is to prevent the annulus grout pour back into the pipe string, the check valve can provided buoyancy and alleviate the drilling rig loading in the process of putting the casing pipe.
After cementing slurry displacement, float collar can also withstand cementing plug and achieve bumping.

-This type automatic self fill-up type float collar and float shoe through the transformation of a single valve to finish the automatic filling. Setting a steel ball groove on the valve rod,loading the ball before going down, the ball stick in the body, so that the spring can not be reset, keeping the upper and lower portion of the valve is transparent. Thus, The liquid of the well can enter the casing pipe which on the top of float collar and float shoe in the process of going down well.keeping the balance pressure inside and outside the casing. When there is downward pressure on the valve rod, to make ball fall, spring return, converted

no-rotating float collar
-Designed no-rotating plug and self-rock plug improve the drilling speed. It easily to grind the plug and plug seat on the action of pressure and rotating when grinding, saving grinding time. There will not be affected in separated drilling mud and water, bumping pressure and so on.
-No-rotating spool compared with no-rotating plug, can significantly imporve drilling speed.
