Fluted Centraliser

The DTI Fluted Centraliser ensures that the wireline tool string is fully centralised within the well tubing. O.D. is usually specially sized to tubing drift or to pass through restrictions. Large fluted flow paths are incorporated into the O.D. to maximise fluid by pass and shoulders are fully bevelled to prevent tool string hang up.

DTI Fluted Centralisers are available in one-piece solid form (CFS), or as Slip Over type (CFM), which can offer increased value where a series of centraliser diameters are required.
