OBH Mechanical Hinged Bow Spring Centralizer
The OBH non-welded, mechanical, bow spring centralizer with hinge is designed for vertical, slightly deviated and less challenging wellbores.
High performance is combined with the easy field assembly. As it can be nested on a pallet, the OBH provides up to 30% lower delivery and storage costs compared to a non-hinged centralizer.
The bow springs are manufactured from high quality alloy steel, hot bent to shape using dies and then heat treated under controlled temperature and time cycles for consistent spring characteristics.

- Designed to exceed API 10D
- Extended profile
- Easy field assembly
Targeted applications
- Onshore
- Vertical and slightly deviated wells
- Reach <10,000 ft
- Build rates of < 10 degrees / 100’
