Description
314212 212 215 215 Rigid Centralizers with Rollers (RCR)

Features:
The Rigid Centralizer with Rollers consisits 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 betwwen 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 cementation of deviated holes and horizontal holes.

The bow springs of this centralizer have two types as follow: non-welded single bow spring centralizer and non-welded double bow spring centralizer. The centralizer are attached to the end rings without welding. The bow spring casing centralizer bow end is connected to the end rings with a locking tab that bears the load force on the centralizer. The centralizers are supplied in hinged segments joined by hinge pins in each segment. All non-welded centralizers meet or exceed the requirements of API Specification 10D, which dictates the minimum restoring and maximum starting forces for centralizers for various casing/hole size combinations.
Advantages:
1) Designed for high restoring force and low running force.
2) End collars are designed with self-locking action, which are easy to assemble.
3) Undergo special coating process to prevent from rust.
4) Can be shipped in half assembled condition for economy in shipping and storage costs.
