Compressed Air Piping Compressed Air Piping Piping selection directly affects the three key elements of every compressed air system: flow, pressure, and air quality. Poor choices in pipe materials, diameter, and layout cause flow restrictions, often resulting in significant pressure drop. Pressure drop is a main cause of increased energy consumption and under-performing tools and equipment. Choices in piping also directly impact installation costs. Heavier materials increase fatigue and slow work, especially in overhead installations. Also consider the types of fittings to be used. Some connection types cause pressure drop, need special tools, and take more time to install. SmartPipe System Benefits Kaeser’s SmartPipe is a modular compressed air distribution system that offers both lower installation costs and lower long term operating costs. It is an excellent choice for compressed air and inert gas distribution for pressures up to 188 psig (13 bar) (consult factory for higher pressures) in temperatures from -4°F to +140°F (-20°C to 60°C). SmartPipe is also ideal for vacuum up to 98.7% (29.6” Hg).
