Aluminum Spiral Vane Solid Rigid Centralizer -DAS02
Available in 3 1/2" to 20 "sizes + any special sizes

Aluminum Spiral Vane Solid Rigid Centralizer

SledgeHammer's Aluminium Spiral Solid Centralizers are developed in response to the need for better cementing in high deviated and horizontal well. These are designed to provide optimum flow and its fins or blades overlap the entire 360-degree open hole circumference. Therefore its reduced flow area between the spiral provides and creates vortex motion to increase fluid velocity with direction.

 

Even without rotation, the relived angle fins/ blades induce turbulent flow for improved cutting and filter cake removal. The angle of the uniquely designed spiral fin produced maximum fluid swirl, thus maximum removal of debris around the casing in any type of hole. These Centralizers withstand high well bore temperature while providing maximum horizontal standoff.

Steel Twin Blade Rotating Centralizer -DSR02
Available in 3 1/2" to 20 "sizes + any special sizes

Steel Twin Blade Rotating Centralizer

Sledge Hammer's Steel Twin Blade Rotating centralizers are unique special purpose centralizers because of its design. The Full 360-degree radius fins provide a long lead-in on the fins. This is ideal for running casing in unusually irregular well bores, for guiding the casing and providing the maximum flexibility for the casing string.

 

The 45 degree angled fins create a radial swirling fluid motion when the fluid being pumped. Therefore radial motion eliminates channeling, it pick up well solids from the low side, get the mud out, and put the cement in. This feature provides excellent circumference standoff from the wellbore. The vanes are tapered at the top and bottom which decreases drag during running into the casing or well bore.

 


These centralizers are not fixed to the casing. Its rotates up and down by the use of Stop Collar. Its some how works like a bearing and greatly reduce the torque which is necessary to rotate the casing. Its outer dia is always lesser by 1/4" or 6 mm from wellbore.

Low Torque Roller Centralizer-DZRD01
Available in 3 1/2" to 20 "sizes

Low Torque Roller Centralizer

Sledge Hammer's Roller Centralizers are specially designed to run in inclined or horizontal section. The rollers' envelope outside diameter is kept slightly larger than the centralizer fins' envelope outer diameter. The Rollers' envelope inside diameter is kept slightly larger than the fins' envelope inner diameter.

 

 

When casing equipped with Roller Centralizer runs into the deviated or horizontal hole, the 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.
