Widespread corrosion in LTHW and CHW systems

Widespread corrosion in LTHW and CHW systems

 

Building: Large Business Park

Manifestation: Blockage of pipework, failure of boilers and condenser coils

Cause: Insufficient installed expansion capacity and poor maintenance of system pressures leading to large water losses with consequent gross aeration of system water and loss of inhibitors.

Solution: Remedial flushing of pipework where possible but large replacement of pipework and system components necessary. Installation of larger expansion vessels and increase to system pressure.  Proper maintenance regime introduced.
