Centralizers and Accessories
Hinged, Welded, Imperial Bow Centralizer
The 700 Series Centralizer uses hinge pins to secure the hinged designed end collars together around the casing, while straight bow springs are welded onto the end collars. The design is hinged for easy installation and is normally run over a stop collar or coupling.
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.
- Decreases RIH time
- Multiple units per casing joint can be installed as needed
Anchored to the casing via one of Antelope’s unique proprietary technologies--either the WearSox® thermal spray metal or MCC mechanically bonded stops--the PT1 guarantees an excellent cement job.
The RT1 is a close tolerance centralizer that provides operators 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.
- Extremely low friction and coefficient levels
- Single piece of steel means no welds on bows for enhanced integrity
The unique design prevents the anchoring device from getting underneath in interface between the bows and the end collars, increasing safety and maximizing performance.
We custom build each WearSox® Centralizer with machine-shop accuracy according to the requirements of each job.
- Free-standing blades with no connecting collar maximizes flow-by area
- Minimizes impact on equivalent circulating density (ECD)
However many blades you need, whether helical or straight, in whatever dimensions, we make it to order. Using computer simulations, our knowledgeable team can help you determine the ideal number and placement of centralizers needed, as well as make dimensional recommendations for all casing and hole size combinations.
