S2 Hinged Centralizer

S2 Hinged Centralizer

The S2 Hinged centralizer is high strength, two-piece centralizer for offshore application where slip-on centralizers cannot be used due to oversized casing connectors.

No compromise in strength

Correct top hole cementation is critical. Use of quick connect-type couplings has created a need for hinged centralizers. However, due to pipe weights and well geometries traditional latch on units often fail leading to costly delays or a poor cement sheath. The S2 hinged unit is different. Made from hardened, high grade steel it has a joint strength unparalleled in the industry.

Hinged stop collar

A hinged stop collar has been developed using the same technology to accompany the hinged centralizer. This has a holding force comparable to Centek’s heavy duty stop collar range.
