Quality of Work After HMG’s high-quality, high-pressure cleaning system is utilized, the pipe is clean and ready for steam or air blows.

Process

Process Overview Hydro-Milling Group offers the latest in high-pressure 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.
