Solid Body Low Torque Roller Centralizers are specifically built to run in an inclined or horizontal section. The rollers outside diameter are kept slightly larger than the centralizer blades outer diameter.
When casing equipped with Solid Body Low Torque Roller Centralizer runs into the deviated or horizontal hole, sliding friction between the casing and the borehole is converted into rolling friction. In case of irregular hole diameter, the borehole wall has an impact force on the spiral centralizer during running casings, the use of rollers reduce this impact.
Torque reduction is provided by vertical alignment of rollers on the periphery of Roller Centralizer.
Used when high torque is anticipated
Smooth rotation of the casing facilitates improved cementing and movement of casing to the bottom Run in conjunction with high-strength stop collars
Non weld bow centralizers are available in the sizes 4 1/2" to 13 3/8"
Any special sizes or combination can be made available on request
