AIR Springs Supply has highlighted the use of its lifting bags to reposition and reduce stress on pipelines. The diversity of terrain and climate conditions across Australia provides particular challenges in the operation of long-haul pipelines. Having pipes running in good working order is vital for the security and safety of the fluid they are carrying. A single pipe may run over hundreds of kilometres and encounter everything from hills and ridges to gullies and trenches. The pipes have to be lifted or relocated in order to avoid such problems. This can inflict potentially dangerous strains on the structure. The Nacap group specialises in the layout of industrial pipelines. They use Pronal lifting bags to position the pipelines without creating excessive strain. Gauges along sections of the pipeline guide the rate of inflation needed for each particular structure. The company says the movements can be as small as a single millimetre and are more precise than hydraulics. CLP 67 cushions have the capacity to lift 67t as well as the ability to spread evenly over an area for smaller-scale control. The pipework provider claims the bags provide gentle handling of the pipes, resulting in a safer workplace, a lower risk of infrastructure damage and a more secure pipe system.
