Shoes

Shoes
Shoes are usually used in the lower interval of the well and provide a reduction in the load on the mast when running the casing through zones with ledges and collapses in the wellbore, as well as landing sites for the lower and upper cementing plug. The back pressure valve prevents fluid from flowing into the casing when the pipe is lowered into the well and prevents cement entry back into the casing after injection, while allowing circulation through the casing.
Float Valve
Designed for use in wells with high velocities and volumes of pumped liquids, under conditions of expanding flow. We produce valves of two types: conventional check valves and valves with an autofill function, which allows filling the column with drilling fluid during the descent. In the event that a redundant design is required, the valves can be stacked one above the other. All valve elements are easily drilled with PDC chisels.
Collars
Designed for well applications where high abrasive fluid content is observed and high velocity of fluid circulation is required
