Spiral Bow Spring Single-Piece Centralizer
Next-Generation Centralization Performance for Demanding Wells
​
The PDG Spiral Bow Spring Single-Piece Centralizer is engineered to deliver maximum stand-off, superior fluid displacement, and dependable downhole performance in today’s most challenging cementing environments. Designed and manufactured as one integral piece from high-strength spring steel, the tool eliminates traditional weld points—removing weak links and ensuring unmatched structural reliability across all well profiles.
The spiral-formed bow geometry enhances 360° wellbore contact and creates efficient turbulence for improved mud removal and cement bonding. This results in a more consistent and durable cement sheath, supporting long-term zonal isolation and well integrity.
Built to meet or exceed API 10D performance requirements, the centralizer delivers exceptional restoring force while minimizing starting and running forces—enabling smooth deployment through tight spots, ledges, doglegs, under-reamed sections and highly deviated or horizontal wells. Its low-drag design supports casing rotation and reciprocation, reducing differential sticking risk and enabling optimal cement placement.
