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.
Features and Benefits
- High restoring force
- Strongest proven hinge of any latch on centralizer
- Specially designed pins
- Time reduction on installation
- Can be transported or installed on the pipe rack with no damage potential
- Made to gauge units with no start or running forces
- High stand-off ratio’s ensuring a good cement operation
