Centralizers

Centralizers

  • Made from seamless tube.
  • No weakness point, no possibility to drop into the downhole.
  • Robust single piece design, suitable for onshore installation.
  • Flexible design reduces running forces through any cased hole restrictions, has an extremely low co-efficient of friction, speed the process of running casing liners to final depth.
  • Adjustable O.D. provides maximum stand-off in any open-hole section ensuring ideal conditions for uniform cementation and reducing the effects of channeling.
  • It can traverse tightspots such as under-gauge sections, and once clear, automatically regain its original size and shape.
  • Manufactured and tested to meet API10D specification.
  • Steel board rolled ones as a more economic option.
  • Sizes are available for all standard casing/hole sizes. Also can be made to meet your specific requirements.

Rigid Casing Centralizer

  • Made from seamless tube.
  • No weakness point, with no possibility to drop into the downhole.
  • Designed to meet 10-15T load with no collapse.
  • Stamping process produces high-quality, high-strength product.
  • The smooth body shape reduces running forces and are perfectly suited to today’s complex well designs.
  • Remain intact during installation and withstand the side loads resulting from extreme tension in deviated wells.
  • Provide positive centralization ensuring cement displaces the drilling mud and forms a good seal.
  • Spiral blade and straight blade are available.
  • Sizes are available for all standard casing/hole sizes, and can be made to meet your requirements.

Slip-on, Roller Wheel, Spiral Rigid Centralizer

  • Changes the sliding friction to rolling friction, significantly reduces the coefficient of friction and rotation torque to facilitate the easy running of the casing.
  • Have a high wear and side load resistance.
  • Easy to install.
  • Spiral blade and straight blade are available.
  • Cast steel and cast aluminum are available.
  • Sizes are available for all standard casing/hole sizes, and can be made to meet your specific requirements.

Hinged, Non-Welded, Bow String Centralizer

  • Bow Springs manufactured from high quality spring steel and heat treated to provide strong restoring forces while keeping the starting and running forces at a minimum.
  • Every attachment is pressed into the shape by moulding instead of welding and rivet.
  • Integral hinges designed for maximum load capacity for optimum design strength.
  • Easy to install and offers unique ability to ship unassembled, providing savings in shipping and storage costs.
  • Manufactured and tested to meet API10D specification.
  • Single bow spring type and double bow spring type are available.
  • Sizes are available for all standard casing/hole sizes. Also can customize to meet your specific requirements.
