OBH-W welded hinged Bow Spring Centralizer
The OBH-W is a high-performance hinged, welded bow spring centralizer designed to deliver robust reliability in less challenging onshore wells. Featuring heat-treated, spring-steel bows welded to rigid high-strength end bands, it ensures optimized stand-off and casing centralization. Centek's proprietary metallurgy and heat-treatment process enhance the OBH-W's strength and flexibility, minimizing start and running forces to ease casing installation to total depth (TD). This innovative design undergoes rigorous in-house testing to consistently deliver superior performance compared to competitors.
The OBH-W is equipped with an integrated hinge that allows for quick, secure installation, making it an economical choice for vertical and slightly deviated well applications. Its design accommodates use over casing couplings, offering versatility in operations where slip-on centralizers are not viable. For enhanced reliability, a corresponding range of high-strength hinged stop collars is available. The OBH-W is an ideal solution for operators seeking a cost-effective yet performance-driven option for onshore wells.

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.
Sizing
Available to suit casing sizes ranging from 4 1/2" to 26".
