Solid Rigid Centralizer

Centralizer, roller centralizer, rigid centralizer, API proved.


The RCR centralizer, rigid centralizer with rollers, consists of a rigid body, on which machined five spiral blades and streamlined diversion trenches between blades. On every spiral blades, there are three or four rollers made from modified alloy steel fully heat treated. The assembly is shown as following fig. Because of the rigid body and rolling friction between the rollers and inside wall of well or casing, the capacity of the RCR centralizer is better than others of all. Recommend to use the tool in cementing of deviated holes and horizontal holes.


Solid rigid centralizers are one series of casing centralizers as integral part of cementing process, centers the casing in the well bore and make the cement flow around in the casing. We provide several kinds of solid rigid centralizers for matching different casing size and well bore size. The solid rigid centralizers ensure positive centtering in deviated or horizontal holes. The solid centralizers are have steel or aluminum body construction, with high tensile and yield strength, shock, impact and corrosion resistant. Spiral or straight blade centralizers, roller centralizers are available.


Rigid Centralizer provides mechanism that centers the casing in the hole and allows uniform cement flow around the casing to help protect it at all points. Efficient in the cementing process, we provide this machine in various specifications and hole sizes, including turbulence generating designs. It helps to clean the annulus and distribute the cement more evenly and uniformly.
