Pre-Commission Cleaning of Pipework Systems

What is Pre-Commission Cleaning?

Pre-Commission Cleaning is vital for maintaining the efficiency of closed loop systems, as modern equipment is more vulnerable to blockages caused by system contaminants like mill scale, jointing compounds, and fabricating debris. This process involves flushing pipes and chemically treating the system to remove debris, ensuring the water cleaning regime can effectively prevent corrosion and microbiological fouling. This must be carried out on any new systems to ensure water quality is satisfactory at the beginning of a systems life.

 
Flushing with water alone often fails to remove contaminants, making pre-commission cleaning essential. For existing systems with accumulated deposits, similar methods can restore performance

At HBE, our process aligns with BSRIA AG 1/2001.1 and BG 29/11 guidelines, involving:

This comprehensive approach guarantees system cleanliness, enhances efficiency, and ensures compliance with industry standards. Contact HBE for tailored solutions to meet your pre-commission cleaning needs.

FAQs for Pre-Commission Cleaning​

Pre-commission cleaning is the process of cleaning and flushing a new or existing water system to remove contaminants like millscale, jointing compounds, and debris, ensuring the system operates effectively and is free from harmful bacteria.

It prevents blockages in pipes, removes potential contaminants, and ensures the water system is safe for use, especially before regular water treatment control measures are implemented.

The process includes high-velocity flushing, chemical cleaning, bio-washing, and regular testing of water quality, followed by the addition of inhibitors and biocides.
