Digger – Non Welded Bow Spring Centralizers are designed for vertical, deviated and horizontal well for enhanced restoring force combined with low starting force ensuring good zone isolation. Bow springs are of high quality alloy steel, hot bent to shape using dies and then heat treated
under controlled time cycles for consistent tensile strength and spring characteristics for “spring back” action.

Features :

1. Extended profile prevents them from hitting

against casing collars

2. Five standard size Bows can be configured

to any hole diameter

3. Special zinc Phosphate and powder coating
