Product DescriptionBasic floating Equipment includes the Float
Collar and Float Shoe:The Float Shoe contains a backpressure 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 Collars are placed one to three joints above the
Guide Shoe or Float Shoe. 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. The space
between the Float Shoe and the Float Collar provides a containment
area to entrap the likely-contaminated fluids from the wiping
action of the top cementing plug, securing the contaminated fluid
away from the shoe where a strong cement bond is of primary
importance. Float Collars include a backpressure valve and serve
basically the same function as the Float Shoe.Product

inner string cementing of large diameter casing.2. Displacement
volume and cementation time are reduced.3. The valve is made with
phenolic material and molded with high strength concrete. Both the
valve and concrete are easily drillable.4. Excellent performance
for flow endurance and back pressure holding.5. Single valve and
double valve versions are available.drawing sheetcompany
