Rotational Scale Scraper

Reduce operational cost by Milling Scale with Slickline.

The DTI Rotational Scale Scraper uses a High Torque Spline Jar to rotate Scraper Mill Blades in opposite directions. Repeated down jarring drives the Mill Blades through the scale with a downwards and rotational action.

The DTI Rotational Scale Scraper blades are designed to simultaneously engage with scaled tubing so that all the torque is contained within the tool and not transmitted back into the Wireline.

A built in swivel at the upper end of the DTI Rotational Scale Scraper eliminates the chance of twisting the wireline.

The DTI Rotational Scale Scraper is available with industry standard connections and material to suit your operating environment.
