Aqua Milling® and Aqua Sonic® cleaning of Heat Exchanger


Pipetech were approached to assist with the cleaning of Glycol heat exchanger onshore. The job was performed at our facility in Stavanger. The requirement was to thoroughly clean the heat exchange bundle remotely with no potential to harm individuals or any of the inner tubes.

Utilising Aqua Sonic® software, parameters of the tube bundle were calibrated to ensure no impact or damage to any tube during cleaning. A ram assembly remotely lined up the cleaning nozzle to each tube opening, each tube was filled with water to allow sound waves to cause resonance easing scale from the inner tubes.


Ability to clean the tube’s at only 75% of each tubes yield strength.


Successful cleaning of complex pipework within a time-bound situation without compromising safety.

Unrivalled results, Pipetech continue to remove the toughest scale.


Safety – all cleaning was completed with both product lines remotely.

Best Practice – Aqua Milling® and Aqua Sonic® proven to effectively remove hard scale over other unsuccessful attempts using chemical treatment along with traditional HP water jetting

Delivery – of a tailored solution by working with our client and maintaining zero LTI’s while performing a safe job.
