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.

Performance Features

  • Used in conditions where extra fluid movement and cement slurry distribution are desired.
  • The turbo fins create turbulence during cementing and improve the placement of the cement slurry
  • Designed for use in vertical, deviated, and horizontal wells.
  • A high restoring force combined with a low starting force is achieved with all bow heights.
  • Eneroil’s bow springs are manufactured from high-quality spring steel and heat-treated to achieve minimum starting and running forces. The heat-treated alloy provides flexibility while minimising damage when moving downhole.
  • Eneroil offers a wide range of bow heights and shapes enabling the customer to make an optimum choice matching their starting and restoring force requirements.
  • Hinge locking pins are made of high-strength steel for maximum structural strength.


  • Non-welded hinged bow spring centralizers with turbo fins are available in the sizes 2 ⅞" to 30"
  • Special sizes or combinations can be made available on request
