The Standard Expand-O-Lizer ‘Bow Spring’ range are hinged, non-welded bow-spring centralizers designed to centralize in less demanding well bore applications where rotation is not a requirement. The hinge allows the centralizer to be fitted on larger bore casing where weld on connectors do not allow for a slip-on unit to be installed.
