Non-welded Hinged Bow Spring Centralizer with Turbo Fins
Eneroil’s non-welded hinged bow spring centralizers with turbo fins induce a spiral-flow pattern in the slurry, thereby increasing displacement efficiency. Fitted with specially-designed multi-direction turbo fins, these centralizers improve the cleaning action of drilling fluids, distribute the cement slurry into wellbore irregularities and minimise channeling. These centralizers reduce the effect of channeling by improving cement flow. This results in a highly uniform thickness between the casing and the wellbore. The centralizers are also able to minimise gas channeling by reducing the movement of the pipe before the cement sets in. Additionally, the centralizers provide a semi-rigid casing standoff.
A non-welded design features the self-locking of lips for holding bows to end collars. Bows of special alloy steel are hot-formed and then tempered for optimum strength, resilience, and uniformity. The turbo fins are made of alloy steel in an annealed state and are attached to the bows from inside.
