Flow Activated Expanding Bow Spring Centraliser

The CT Expanding Bow Spring Centraliser is a hydraulic tool with normally retracted bow springs. When CT fluid flow/pressure at the tool is increased, the bow springs will expand to the tubing I.D. and centralise the tool string. This feature provides an efficient method of centralisation and greatly reduces the wear and tear on the springs. The bow springs are replaceable and easily changed out without the need to completely disassemble the tool.
