Having designed and maintained numerous compressed air systems across industrial facilities, I’ve witnessed the consequences of material selection decisions that prioritized cost over safety and performance. While PP-R offers apparent advantages, the safety realities tell a different story that every professional should understand. Metal piping systems consistently outperform PP-R for compressed air applications when considering […]

Throughout my career working with various piping systems, I’ve encountered numerous installations where PPR pipes were incorrectly specified for compressed air applications. The standards landscape for this specific application reveals why this practice poses significant safety concerns that professionals cannot ignore. No international standards specifically govern or approve PPR pipe usage in compressed air systems.

I must begin with a crucial safety disclaimer: most manufacturers explicitly prohibit using PP-R pipes for compressed air systems due to significant safety risks. However, recognizing that some installations proceed despite these warnings, I’ll share essential techniques that theoretically minimize leak risks while emphasizing that proper material selection remains the safest approach. Preventing leaks in

As someone who has worked with various piping systems, I need to address a critical safety concern upfront. While this article explores PP-R’s theoretical advantages for compressed air, most manufacturers explicitly prohibit this application due to safety risks. My professional experience confirms that specialized materials better serve compressed air systems. PP-R pipes offer certain theoretical

I have witnessed multiple workshop accidents resulting from failed plastic pipes in compressed air systems. Although PP-R performs excellently in water applications, compressed air presents completely different challenges that many installers only understand after accidents occur. The safety implications are too significant to ignore. Manufacturers do not recommend PP-R pipe for compressed air systems due
