S2 Hinged Bow Spring Centralizer

S2 Hinged Bow Spring Centralizer

The S2 Hinged centralizer is high strength and engineered for challenging applications typically requiring a single piece product.

The NEW Centek S2 Hinged centralizer has a unique twisted hinge with a one of a kind “one way” hinge pin.

In tests this new centralizer has proven to have the strength and performance of our industry leading single piece centralizers, but with up to 30% lower transport, storage and installation costs due to product’s ability to be nested on a pallet.

Fitment times are comparable to a slip-on centralizer due to the quick fit, one-way pin with one hinge delivered pre-pinned.

Centralizer application guide

[These units are not designed to fit over stop collars or casing collars. Installing over collars limits performance and could result in damage]

Performance ratings

Centralization and the ease of running casing is often a balance between strength and flexibility which combine to support, what we call, 'runability'. To help with product selection we've added a rating to all our products for flexibility, runability and inherent strength.
