The WBS series offers a large range of centralizers and are designed for durable, superior performance. All configurations use heat treated, spring-steel bows, reinforced collars and manufactured using an automated process, producing strong, uniform welds. Manufactured to be slightly over wellbore ID, these centralizers offer minimal starting and running forces along with exceptional restoring forces. Integral hinge design allows for ease of installation at the wellsite. The centralizer can be installed over the coupling or stop collar, between stop collars or between a stop collar and casing coupling.
