The S2-HD Bow Spring Centralizer is engineered to provide exceptional strength and reliability in the most challenging well conditions.

This heavy-duty version of the patented S2 centralizer is constructed from a single piece, ensuring no weak points and delivering ultra-high durability essential for high-load environments where traditional solid centralizers might be used. The S2-HD is specifically designed for casing-running situations in which heavy loads and extreme forces are at play.

Beyond its unmatched strength, the S2-HD is designed to enhance operational efficiency. It maximizes flow area, reduces torque, and enables smoother rotation and reciprocation during run-in-hole (RIH) operations, which can significantly streamline well operations and reduce risks associated with high-friction environments. The centralizer is rigorously tested to exceed API 10D standards, giving operators confidence in its performance across a wide range of challenging applications.

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"
