Each CentraMax® Casing Centralizer is backed by our industry-leading, real-time customer support, combined with state-of-the-art placement, T&D and surge software, making them your best choice for dependable one-piece-centralizer performance.
One Piece Casing Centralizers
Our CentraMax® One Piece Centralizer line includes the RT1, PI1 and PT1 models that offer different bow geometries, allowing you to choose the design you need to reduce starting and running forces in any given 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 centralizers yield superior mechanical integrity and provide an extremely low coefficient of friction. Multiple units per casing joint can be installed as needed.
RT1, Rotating Technology
The CentraMax® RT1 is a close-tolerance centralizer that provides a technically superior alternative to in-line centralizer subs. It is pulled in both directions using either a WearSox® or MCC band inside the centralizer between end collars, leaving the RT1 free to rotate. 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. It is always pushed when installed between two external anchoring devices – either WearSox® thermal spray or MCC mechanically bonded stops. 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. Anchored to the casing by one of our unique proprietary technologies – either the WearSox® Thermal Spray Metal or Multi-Layer Composite Bonded Stops – the PT1 guarantees an excellent cement job.
CentraMax® Quick-Lock Stop Collar
The CentraMax® Quick-Lock Stop Collar is utilized with the CentraMax® CT Centralizers. This fast and simple installable stop collar eliminates the need to ship casing to installation locations. The stop collar provides high-holding forces, up to 150,000 lbs. The Quick-Lock can be installed anywhere on the casing by sliding the stop device on to the casing with the centralizer and removing the shipping screws once the desired location of the stop is reached. Both uni- and bi-directional designs are available.
