Steel fabrication plant gets IAS system installed
Industrial Air Systems NZ has installed its Pneutech Aluminium compressed air piping system into John Jones Steel fabrication facility in Timaru.
With more 4000sq m of workshop facilities, John Jones was adding new state-ofthe-art plate cutting and drilling equipment, which was requiring more compressed air than what was available. Re-sizing their actual compressed air requirements was the easy part, with the installation of a new single 37 kW VSD compressor to supply an energy-efficient air supply, and coupled to filtration and refrigerate dryer for the best instrument-quality air.
However, it was quickly established that the existing dated and leaking galvanised air piping system was not of sufficient size quality, or layout to reticulate the new higher quality compressed air supply to the various working points required.
Furthermore there would be very little gain from the new compressed air plant, unless the piping system was also upgraded.
John Jones Steel’s new plant was requiring contaminantfree compressed air, both for the safe operation of CNC equipment, and to produce the highest quality and most cost effective results. The ageing galvanised piping was found to have internal rusting, leading to air contamination that would have a detrimental effect on plasma cutting, while causing premature and costly plant wear.
As with any galvanised piping installation, the system was also found to be fraught with air leaks, which when added together would be costing many thousands of dollars every year in wasted energy.
Industrial Air Systems’ director says: “The air compressor is really only half the compressed air story, the other half lies with the air treatment and most importantly, the air reticulation system.
“Like water, you can have the largest and best supply in the world right on hand, but unless it can be piped to where it is required, it is of little use.”
Industrial Air Systems provided the optimum solution by installing the premium quality Pneutech Aluminium air pipe system, with more than 450m of 32mm ringmain, feeding 30 20mm droppers at each work station.
The high seismic and yet rigid characteristics of the extruded aluminium meant that it was very simple to hang, and with no risk of bows or sags, troublesome water collection points in the air line were eliminated.
The much larger and smooth internal bore of the Pneutech Alu Air piping, ensured higher compressed air f lows were achievable with the least turbulence effect, (when compared with galvanised or poly piping).
This ultimately leads to large energy savings, as the air compressor could operate at a lower pressure, in turn using less electricity, but for the same air capacity.
A complete ringmain system, meant pressure and f low continuity was assured at every workstation, despite an imbalanced workload, while the simple push-lock style fitting design, allowed for the system to be quickly and simply altered or extended at any time.
The simple expanding O-ring design ensured there were no costly air leaks, while risk of rust corrosion was completely removed.
Industrial Air Systems NZ predicts that the Pneutech variable speed compressor and aluminium pipe system, will bring John Jones Steel thousands of dollars in energy savings every year.
