Product Description
Application
Float Collar & Float Shoe serves as the backbone of casing equipment used during primary cementing operations. It guides the casing to total depth and prevents contaminated mud from entering the casing. Also it provides a landing point for casing wiper plugs, reinforces the lower end of the casing string, and ensures greater accuracy of cement slurry displacement.
Features of Stab-in Type Float Collar & Float Shoe:
a. For float shoe, the rounded nose profile helps guide the casing string.
b. The valve is made with phenolic material and molded with high strength concrete. Both of the valve and concrete are easily drillable with PDC or rock bits.
c. High strength design ensure excellent performance for flow endurance and back pressure holding.
d. Saves considerable running-in time with automatically fill up.
e. For non-rotating Float Collar & Float Shoe, the special non-rotating groove design ensures corresponding cementing plugs drilled out quickly.
