Integrated Hinge with One Way Pin

The Centek S-H Hinged centralizer is a high-strength solution engineered for challenging well applications that would typically require a single-piece design.

Featuring a unique twisted hinge with one-way pin, it combines the strength and performance of Centek’s industry-leading single-piece centralizers with up to 30% savings on transport, storage, and installation costs. This is made possible by its ability to nest efficiently on a pallet.

Fitment is quick and easy, with one hinge delivered pre-pinned, achieving installation times comparable to slip-on centralizers. This design makes the S-H ideal for land, offshore, and deepwater wells, highly deviated wellbores, long lateral runs, and situations where slip-on centralizers are not feasible.

The S-H offers several advantages, including a reduced carbon footprint due to minimized transport and storage needs, and each unit is made to gauge for precise fitment. The high standoff ratios promote effective zonal isolation, providing added value and efficiency in demanding applications.

Key Benefits

  • Tested to exceed API 10D
  • Integrated, low profile twisted hinge with “one way” hinge pin for secure fitment – as strong as a single piece centralizer
  • Safe and quick installation
  • Can be transported on pipe, installed on the pipe rack or rig floor
  • Minimized “carbon footprint” reduces cost of transport and storage
  • Made to gauge - no start or running forces
  • High standoff ratios enhance zonal isolation

Targeted applications

  • Land, offshore and deepwater
  • Highly deviated wells
  • Wells with long lateral runs
  • Applications where slip-on centralizer can’t be used

Stop Collars

Redesigned 00SH and HDSH stop collars has been developed using the same hinged design. Holding forces are comparable to Centek’s industry leading single piece stop collar range.

"Good decision to use the Centeks. Due to the development costs we had to invest more money, but the job went well and the investment was worth the money.”
