Bow-Spring Coiled Tubing Centralizer

This bow-spring centralizer centralizes the casing while enabling downhole tools to be held away from the casing.


The coiled tubing centralizer (bow spring) is designed for use with coiled tubing tool strings or when running downhole gauges out through the tail pipe and into the casing. It passes through the restricted bores of the tail pipe and expands into the casing liner below, enabling the tools to be held away from the casing.

Logging, fishing, camera work, and liner-lap crossing are only a few of the challenges this proven tool has overcome. A full pump-through bore, modular or custom threads, and resistance to corrosion make this centralizer a necessary component for specialty work.
