Offering easy installation and excellent casing centralization for vertical, deviated and horizontal wells, Innovex’s hinged non-welded bow spring centralizers are available for all standard casing/hole sizes. The imperial bow spring design of the 800 Line provides strong restoring forces while keeping the starting and running forces at a minimum. Our high-quality centralizers also reduce the effects of channeling by improving the cement flow, creating a more uniform thickness between the casing and wellbore.
The 800 Series features straight, non-welded bow springs that are attached with rivets onto the hinged end collars. Normally run over a stop collar or coupling, this centralizer uses hinge pins to secure the hinged designed end collars together around the casing.
807 – Hinged, Non-Welded, Bow Spring Centralizer with Turbo Fins
This centralizer consists of straight, non-welded bow springs with the addition of spot-welded turbo fins that are attached with rivets onto the hinged end collars. The turbo fins induce a spiral flow pattern to cement slurry and assist in the removal of mud cake, and help reduce channeling during cementing operations.
