Pre-commission cleaning of pipework

BSRIA, commissioning, cleaning pipework

BSRIA has updated its guidance on ‘Pre-commission cleaning of pipework systems’ in response to industry feedback. The new guide replaces the previous edition, dating from 2001. Thorough pre-commissioning cleaning of pipework has become even more important with the adoption of energy-efficient control strategies that may result in low flow rates, particularly in terminal units with very small orifices in control valves.

Pre-commission cleaning is achieved through a process of flushing and chemical cleaning, where required, followed by the addition of biocides and inhibitors. Systems designed and cleaned in accordance with BSRIA’s guidance are far less likely to experience operating problems.
