• OBH Non-Welded Bow Spring Centralizer

The OBH non-weld hinged, bow spring centralizer 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.

Features and benefits:

• Extended profile
• Easy field assembly
• Supplied with stop collar and hinge pin
• Testing exceeds API 10D standards

Targted applications

• Onshore
• Vertical and slightly deviated wells
• Reach <10,000 ft
• Build rates of < 10 degrees / 100’
• Applications where slip-on centralizer can’t be use

Stop collars

A redesigned stop collar has been developed using the same technology. Holding forces are comparable to Centek’s industry leading single piece stop collar range

Performance ratings

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.
