This centralizer is made of high-strength, corrosion-resistant cast aluminum. They can be used with corrosion-resistant alloy casing strings to avoid the effects of galvanic corrosion. Their spiral blades fully overlap to give 100% wellbore coverage and increase annular turbulence to improve wellbore cleanout.
The centralizer provides a positive standoff in the wellbore, enabling cement to be evenly distributed around the casing string.
The 45° spiral blades provide increased velocity with a turbulent motion that optimizes mud and cement displacement, which maximizes the likelihood of achieving zonal isolation with primary cementation and minimizes the need for remedial cementing operations.
