Process
Process Overview

Hydro-Milling Group offers the latest in highpressure hydro lazing for mill scale removal (new
power plant construction).
 Our process utilizes a 510 hp continuous duty Duetz
engine and K-35000 Kamat high-pressure pump
which is coupled to the “Hurricane” system. This
cleaning process is state-of-the-art and provides
superior pipeline cleaning ability.
 A rotational feeder controls the nozzle tracking and
cleaning path.
Process Overview

As the nozzle is rotated around the inner diameter of
the pipe, all mill-scale, weld slag and debris is
removed from the inner surface of the pipe.

The thrust jet ensures the cleaning jets are held
closely to the interior pipe wall.
Equipment

All Hydro-Milling rigs arrive on site
equipped to handle every anticipated need.
Mobile Control Room/office

Hydro-Milling Group rigs arrive on site complete with a
mobile control room/office.
