Cooling plants within data centers must always comply with the relevant local building regulations. Within which there are requirements relating to fire protection and fire classification.
Oxygen can intrude into a piping system via mechanical joints and also through the walls of pipes with a low density. This is an engineering topic specific to all piping hydraulic systems, namely evacuation of accumulated air.
Data center designs often need to undergo a seismic or earthquake simulation. GF Piping Systems offers a "Seismic Performance" engineering report service via the ROHR2 software.
