OPR Mechanical, Hinged, Positive Stand-off Rigid Centralizer
The OPR is a rigid positive stand-off, non-welded, mechanical, hinged centralizer developed for less challenging wells.
The OPR offers an economical alternative to solid body centralizers in a rigid design that maximizes fluid dynamics and provides optimized stand-off, typical of rigid centralizers.
This non-welded product utilizes mechanically connected ribbed bows and a traditional hinge design for easy installation.
Features and benefits
- Good centralization in less challenging wells
- Economic choice
- Positive stand-off
- Maximizes fluid dynamics
- Vertical wells
- Slightly deviated sections of the wellbore
- Applications where slip-on centralizer can’t be used
The OPR is available with stop collar developed with the same hinge.
Centralization and the ease of running casing is often a balance between strength and flexibility which combine to support, what we call, 'runability'. To help with product selection we've added a rating to all our products for flexibility, runability and inherent strength.
Available to suit casing sizes ranging from 4 1/2" to 18 5/8".
