Description
API float equipments - 9 5/8" stab in float collars and float shoes
API Cement tools Float collar float shoe are necessary conventional accessories for down-structure of casing string. float collat and float shoe is a heat-resisting, sealer and drillable tool. it's join easy and replace for guide shoe and casing shoe. it's used to protection casing and production casign, also used to deep well and ultra deep well. it classify ordinary type and self fill-up type according to way of drilling fluid get into.
The Non-rotating 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 FS 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.

The Float Collars and Float Shoe are used to guide the casing to be put into the hole. It can adjust the floating power of the casing when the casing been laid in. That can certify the qualification of the cementing. The Float Collars and Float Shoe manufactured by our company use the Spring Driving back-pressure valve type. It has a high reliability.
The structures are similar between Float Collar and Float Shoe. The lower end of the Float Collar is the pin connection which is connected with the casing. The upper end which is used for filling the cement has tinfoil hole which can avoid the twist.
