VAN RUTH® Float Shoe & FLOAT Collar
VAN RUTH® FLOAT SHOES (FLOSHO) and FLOAT COLLARS (FLOCOL) act on the same principle as our BNP but with a non return valve and a heavier duty locking sleeves used for cementing in a casing string or to "float" down a long casing string.
The Float Shoe (Left) is pushed into the foot rod of the rod string and is used where a long casing or rod string is present to "float" the drill string down a flooded drill hole or for cementing in a casing string. The Float Shoe may be drilled out if required.
The Float Collar (Right) is assembled inside any rod of the drill string. It is inserted into rod with a 2 way locking mechanism and non return valve. The Float Collar may be drilled out if required.
