Compressor specialist Atlas Copco has launched a new air pipework system which is the first of its kind to offer anodised internal surfaces as standard. AIRnet's smooth surfaces can cut friction by 50%, minimising the risk of pressure drops and maximising energy efficiency.
Pressure drop can represent a major source of waste during the working life of a compressed air installation – a 3mm diameter hole anywhere within a galvanised steel distribution network caused by corrosion can result in a compressor using an additional 4kW of power to maintain system pressure. Not only that, but steel pipe is heavy, its threaded joints require careful preparation, and its inner surfaces are not smooth. As a result, this restricts flow and promotes pressure drop, which equates to energy loss.
Atlas Copco's AIRnet modular system of corrosion-resistant anodised aluminium pipes are highly durable and feature self-aligning, fully sealed polymer fittings with integrated O-rings that eliminate any possibility of leaks.
The AIRnet pipework is lightweight and, size for size, it weighs five times less than the steel equivalent. It is robust, easy to install and fitting only takes about one third of the time compared to that for a conventional system. There is no time-consuming screw cutting and no need for any special tools or lifting equipment. The pipe can be simply pushed into the polymer fitting, tightened by hand and secured with a spanner. When the aluminium pipe is cut to size, there is no risk of corrosion to the exposed metal and thus no risk of leakage.
Atlas Copco has developed a 3D software package to enable easy visualisation of a planned installation with the flexibility to adjust, modify and validate the layout, as well as to calculate pressure drops in the system. Details are available at www.airnet-system.com.
