Our NWB Series use heat treated, spring-steel bows with reinforced collars. However, they differ from the Welded Bow Style (WBS) and use a locking tab in place of a weld to attach the bows to the hinged collars. 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.
