Float Shoe and Collar
Float Shoe and Collar
PRODUCT INTRODUCTION
Float Shoe is a rounded profile component attached to the downhole end of a casing string. contain a back pressure valve that prevents fluids from entering the casing while the pipe is lowered into the hole and prevents cement from flowing back into the casing after placement, while enabling circulation down through the casing.
Float Collar is a special coupling device are placed one to three joints above the guide shoe or float shoe that contains a check valve to permit fluid to pass downward but not upward through the casing.They provide a seat for the cement plugs, the bottom plug pumped ahead of the cement and the top plug behind the full volume of slurry. Once seated, the top plug shuts off fluid flow and prevents over-displacement of the cement.
Our Float Shoes and Collars are manufactured to API standards and are tested to API-III C. The float shoes and collars have been designed and manufactured to withstand the high temperature encountered and high pressure created by differences in fluid columns when floating, landing and cementing strings of casing.
