OMD Centralizers are designed to meet the challenges of today’s torturous wells that require more rigorous centralization while minimizing drag and maximizing flow area. Many of our centralizers are used to reach TDs of 20K+ FT directional wells reducing run time and often breaking completion records.
Our centralizers are produced by the state-of-the-art hydroforming process, creating even greater flow area while maintaining the proven and patented design. This unique split blade design adds resistance against deformation in tough environments and provides an additional path for the mud to flow during the cementing process.
Most OMD centralizers are designed to free float between casing collars or stop collars, we stock the most common sizes of centralizers for OCTG casing and hole sizes. Custom outside diameters can be designed and built within 7 days with custom shapes (3, 4 and 5 vanes and vane angle). See our inventory page for availability. Also see what's new!
Industry demands for centralization in extended reach wells and high dogleg severity profiles is what led to the OMD centralizer design. The rounded vane ends and rounded sides reduce drag, mechanical sticking tendencies and hanging up on ledges and windows. The spiral vane geometry ensures stand-off from the open hole regardless of the orientation. Longer axial length are available for greater side-load force distribution and the weld-free vane design yields consistent uniformity and reliable dimensions.
Hydroforming makes it possible to manufacture hollow components requiring complex external shapes with favorable strength properties yet producing a lightweight product that is easier for handling on the rig floor and pipe yard. Molds and samples can be made in less than 7 days in most cases, contact us with your needs!
The term “ Hydrostamp™ ” was coined by OMD to describe the process used to stamp a flat metal plate into a cylindrical shape while being Hydroformed with high pressure fluid simultaneously.
High pressure fluid is injected into the part causing the metal to take the shape of a tool or mold cavity. This technique allows for complex shapes to be formed while producing stronger more rigid and lighter premium components in a very economical manner.
As in Hydroforming, the Hydrostamp™ process yields a part with a high level of strength and torsional rigidity in addition to repeatable precise dimensional and contour accuracy.
The Hydrostamp ™ process results in less than 10% variation in blank to finished part thickness, due to uniform elongation of the material. The applied force during the cycle is multi-directional drawing the metal around the tool or into the mold cavity which greatly reduces stretching or thinning of the formed areas and finished parts.
Fixturing
The sections are held in a welding fixture to control positional accuracy and roundness of the finished parts.
Welding
The Hydrostamp ™ sections are welded by cutting-edge state of the art CNC Robotic Technology automated machines. This process ensures accuracy and repeatability on the production floor.
Cost Saving
We developed the Hydrostamp ™ process to be able to manufacture larger diameter parts at a lower cost to the end user. The material cost saving of using flat plate VS pre-manufactured tube is over 50%.
We pride ourselves in recycling and reusing as many materials as we can, our hydroforming process is very environmentally friendly and the little waste we produce we recycle.
Hydroformed casing centralizers for extended reach lateral wells, designed to meet the challenges of today's torturous requirements designed with smooth rounder vane profiles without any welds.
