All sizes of float shoe and float collar for casings are produced.The shell is produced by 35CrMo alloy steel . Internal latch and valve are readily drillable.Their capability of back-pressure is over 25MPa. The threads are complied with API.
Specifications:
20,13 3/8,101/4, 9 5/8, 7, 5 1/2, 5, 4 1/2, 4, 3 1/2.
Function:
Effectively channel the casing into the well, float equipment can not only relief the loading of drill tower during running in the hole with casing, but also prevent the liquid flow back after finish cementing.
Features:
Spring float collar (Type: FC-F), Spring float shoe (Type: FS-FS)
1. Tempeteture spring forge, gluey ball surface, high pressure resistance, designed for use in highly deviated and horozontal well.
2. Designed for high-temperature and drill ability, prevent scouring.
Float Ball Float Collar (Type: FC-FB), Float Ball Float Shoe (Type: FS-FB)
1. Designed for high pressure resistance, decrease friction force.
2. The inner structure has high drill ability, same drill-out I.D as casing.
Usage :
To ensure trouble-free operation, please check the float equipment before using it.
Float shoe connect with the end of the casing, the connection of the float collar to the casing at the distance of 20-30 meters to the end of casing.
Control the speed of running in hole with casing, prevent frail stratum be cracked by the pressure what caused by high speed.
The casing allowed to be hollow less than 200 meters .
