Spiral
Blade Aluminium / Zinc Alloy Solid Centralizers
(S 27)
|
 Steelfabs Spiral Blade Solid Centralizers were developed in response to the need for better cementing in highly deviated and horizontal wells. Steelfabs Spiral Blade Solid Centralizers are designed to provide optimum flow area. The 360 degrees overlapping solid vane provides maximum wall contact and fluid swirl. Reduced flow area between the spiral blades produces a vortex motion of the fluids for more fluid velocity with direction. Steelfabs Spiral Blade Solid Centralizer is made of high strength corrosion resistant cast aluminium and also non-sparkling zinc alloy.
The 30-degree slope of the vane end reduces drag and aids the casing in reaching TD. This gentle flow from the body to the height of the vane will eliminate scraping, gouging or digging into the formation and consequently reduce balling between the vanes. Steelfabs Spiral Blade Solid Centralizer has high impact and shock resistance combined with tensile and yield strength as well as resist corrosion. |
