How to arrange the piping system in the clean room?
As a cleanroom engineering provider, one of the most overlooked yet critical aspects of cleanroom design is how we handle the piping and utility systems. It might not be visible once the room is up and running, but poor pipe routing can become a major source of contamination, maintenance headaches, and even compliance issues down the line.
From day one, our philosophy is simple: if it can collect dust, it doesn’t belong exposed in the cleanroom. That’s why Suzhou Pharma always design piping—whether for compressed air, vacuum, deionized water, or process gases—to be concealed within wall panels, ceiling voids, or service corridors. Exposed pipes not only trap particles but also disrupt laminar airflow and make cleaning difficult. In ISO Class 5 or higher environments, even a small dust buildup on a pipe surface can compromise product yield.
We use sealed chase walls and raised access floors to route utilities neatly and safely. All penetrations are meticulously sealed with non-shedding caulks, and we slope piping slightly where possible to prevent stagnant points. For gases and high-purity liquids, we use electropolished stainless steel and orbital welding to minimize internal contamination.
But hiding the pipes is only half the job. Accessibility for maintenance and cleaning is just as important. We build removable access panels and service hatches at strategic points so technicians can inspect, clean, or repair lines without tearing apart the cleanroom envelope. We also label all lines clearly behind access points—because when downtime is costly, you don’t want someone guessing which pipe goes where.
We once worked with a client who had exposed overhead piping in their cleanroom. They struggled with recurring particle counts and spent hours every week wiping down pipes during cleaning cycles. After we retrofitted concealed routing, their particle levels dropped by over 40%, and cleaning time was cut in half.
At the end of the day, a cleanroom is only as clean as its hidden systems. PHARMA CLEAN takes pride in building utility layouts that are not only functional but invisible—because in contamination control, what you don’t see matters most.
