Solid rigid centralizers is built using cast aluminum or steel materials. Because the diameter is smaller than the wellbore, so the solid rigid centralizers are not as effective as bow spring centralizers in vertical wells. But they are rugged and works well in the deviated wellbores.
Solid rigid centralizers are available with straight or spiral vanes & rollers. And the length can be regular or short lengths.
4-1/2" to 20" standard sizes and customized service help you find the best solid rigid centralizers for oil and gas cementing projects.
