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.
