Volant’s rigid-steel centralizers provide positive standoff, mitigate buckling and facilitate rotation using crimp-on technology to overcome friction and other running challenges. This leads to improved run-ability of your casing string by saving time on the run. The sturdy, helical ribs provide positive stand-off and flow areas for solids removal, improved mud flow and a high-quality cement job. Combining our durable centralizers with an optimized placement strategy provides the best opportunity to quickly and efficiently reach target depth without sacrificing the long-term integrity of your well.
Our patented and proprietary hydroforming technology allows precision forming into a variety of custom shapes and profiles for drilling, reaming and completing critically-challenging, high-profile wells. Full control over HydroFORM® process to design and manufacture custom centralizers for special or unique applications.

*There are several cases where the use of centralizers and set screw stop collars applied to flush or semi-flush joint casings has led to the centralizers and the stop collars piling up over the length of the string. Crimping on of stop collars for a non-rotating application or crimping on of the centralizer itself for a rotating application can mitigate this issue.
