Pipetech has established a strong reputation for successfully being able to remove scale that other service providers continue to struggle with. Our Aqua Milling® is often the only alternative to replacing piping systems and is a fraction of the cost. It has the ability to negotiate bends where PIG tools can’t.

The Aqua Milling® system is extremely efficient and cleans pipework without causing any damage. Pipetech has an exclusive regional license for the Aqua Milling® technology from Aqua Drill International in the USA, and has a wealth of experienced engineers, solving some of the toughest scale problems around.

Aqua Milling® can also be used for waste removal and cleaning inside vessels. In addition the Pipeline in Operation (PIO) unit can clean pressurised environments.
