Welded Semi-Rigid Bow Spring Centralizer consists of dual bow springs welded with end collars for high restoring force in deviated wells, these dual bow centralizers offer better standoff than standard spring bow centralizers and are able to move through tight constrictions, while keeping the casing centered for effective cementing.

These are made with heat-treated special spring steel, offering rigid performance combined with high spring action resulting in desired restoring force for horizontal/deviated wells.
