Centralizer Crimping

Securing centralizers, stop collars and wear bands to the string is required in applications where the string will be rotated downhole. These applications include Casing while Drilling (CwD) and reaming jobs as well as casing running scenarios where there is a need to rotate the string to break downhole friction.

The Volant RTF™ tool features a hydraulically driven collet that crimps accessories onto casing, creating an interference fit. Axial force and torque retention strength results from the radial grip of the centralizer on the casing and friction. When properly completed, only a few inches of crimped length provide enough torque and sliding resistance for most downhole applications.
