Factory Supply Straight Vane and Spiral Vane Aluminum Solid Rigid Casing Centralizer with API 10D Complied
Straight/Spiral Vane Aluminum Solid Centralizer
›Made of high tensile, solid, cast aluminum for shock, impact and corrosion resistance. › Used in areas where a good primary cementing job is required, including deviated and horizontal wells, liner overlaps and shoe joints.
› Suitable for either cased or open hole.
› Spiral vanes fully overlap to give 100% wellbore coverage and increase annular turbulence to improve wellbore cleanout.
› Vane ends are beveled 30 degree relative to the casing centerline to provide excellent lead into restrictions and reduced drag when running in the wellbore. Besides, it keeps running forces at a minimum.
› Wide vanes distribute load from the casing string into the wellbore without gouging.
› Standard size is 4-1/2" to 20". Any special sizes or combinations can be customized on request.
