Casing centralizer is an important cementing tool which could help the casing put into the borehole smoothly and center the casing in the hole. The size of casing centralizer is 4" to 20". There are two kinds of bow spring centralizer and rigid centralizer.
Size Range
* The Single Piece Bow Spring Centralizers are available in sizes 4½" to 20". * Any special sizes or combination can be made available on request.
Slip on Single Piece Casing Centralizer
API single piece centralizer performs satisfactorily in open hole as well as cased hole.These high quanlity product,developed to meet and exceed API 10D specifications for use in highly demanding downhole conditions.Single piece centralizer combines the highest restoring force with zero start force and zero running force.The single piece centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells.
Non-welded Hinged Bow Spring Centralizers are available in the sizes 2 ⅞" to 36" Special sizes or combinations can be made available on request
Hinged Non-weld Bow Spring Centralizer
Hinged Non-welded Bow Spring Centralizer is used to position the casing in the centre of the wellbore in both vertical and deviated wells. These Bow Spring Centralizers reduce the effect of channelling by improving cement flow. This results in a highly uniform thickness between the casing and the wellbore. These centralizers are able to minimise gas channeling by reducing the movement of the pipe before the cement sets in. Additionally, these bow spring centralizers provide a semi-rigid casing standoff. A non-welded design features the self-locking of lips for holding bows to end collars. Bows of special alloy steel are hot-formed and then tempered for optimum strength, resilience, and uniformity.
* The Non welded hinged positive bow Simi Rigid centralizers are available in sizes 4 ½" to 30” * Special sizes or combination can be made available on request
Hinged Non Welded Simi Rigid Casing Centralizer
Hinged Non Weld Semi Rigid Centralizers are uniquely designed with a flat-bottom U-profile of different depths, which permit an extremely high fluid passage. These positive centralizers may be used for both casing and tubing applications that require concentric casing strings. The straight bows provide nearly 100% stand-off (concentricity) when running inside a deviated cased hole, while the self-locking design of the centralizer ensures a firm hold. Furthermore, the non-welded structure eliminates brittle spots and enhances durability.
* Solid Rigid Stamped Casing Centralizers are available in sizes 4 ½" to 13 ⅜” * Special sizes or combination can be made available on request * Available with straight or spiral blades
