S2-HD Heavy Duty Bow Spring Centralizer
This heavy duty version of the patented S2 bow spring centralizer is engineered for ultra-high strength in challenging wells.
Single piece construction means the S2-HD has no weak points. It is designed for casing running environments with heavy loads where a solid centralizer may be used traditionally.
The S2-HD is manufactured to gauge. Its exceptional restoring force is delivered with zero start and running forces and generates high levels of stand-off.

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.

Sizing
S2-HD centralizers are available in sizes from 5 1/2" to 14"
