CentraMax® Close Tolerance Centralizer Subs 
This unique one-piece centralization solution is made from a single piece of 4130 heat-treated steel.
The CentraMax Centralizer Sub includes the RT1, PI1 and PT1 models offering different bow geometries, allowing you to choose the design you need to reduce starting and running forces in any well. Our centralizer product line is cold-formed and then heat-treated for ultimate durability, and easy on-site installation.
These non-welded, close tolerance centralizer subs yield superior mechanical integrity and provide an extremely low coefficient of friction. Multiple units per casing joint can be installed as needed. Anchored using proprietary WearSox Thermal Spray Technology.
CentraMax® Close Tolerance Centralizer Subs
RT1, Rotating Technology
The CentraMax RT1 is a close-tolerance centralizer that provides a technically superior alternative to in-line centralizer subs. The unique design prevents the anchoring device from getting underneath the interface between the bows and the end collars, increasing safety and maximizing performance.
PI1, Push-In Technology
Used as an alternative to centralizer subs, the CentraMax PI1 centralization design allows for both reciprocation and rotation type applications. This first-of-its-kind product provides flexibility of placement and ease of installation onto the pipe.
PT1, Pull-Through Technology
Unique to the market, this centralizer option for ultra-close tolerance applications allows the centralizer to be pulled both in and out of the restriction with specially designed windows in the end collars.
