Climate change drives new focus on tank top protection
As Australia’s drought deepens and the UN warns of the worsening effects of climate change, local industries are moving to protect their water and process fluid tanks from heat stresses, high winds, evaporation, airborne pollution and wastage. “Tanks now are being built to hold their contents more safely and securely than ever before, and protect it for longer and in more challenging operating environments,” says tank bearing engineer and manufacturer Mr David Booty, Manager, Hercules Engineering (a division of Cut To Size Plastics). Steel, concrete and fibreglass water and industrial fluid tanks need secure roofs that can withstand expansion and contraction caused by factors such as increasing climatic and load variations, says Mr Booty, whose company is currently supplying bearings for roofs to protect tanks with surface areas as large as 10,000 sq m (100m x 100m, holding 90ML of water, the equivalent of dozens of Olympic pools). He says such protection is needed for even larger tanks used by industry for applications as diverse as potable, process and firefighting water. “They can hold upwards of 10, 20 or even 30,000 tons of liquid that must be protected from the elements and from pollution to safeguard it for use in water, wastewater, emergency fire protection and high purity industrial processing applications.” A challenge facing developers and operators of buildings and processing plants for industrial and municipal uses is ensuring their top structures can flexibly cope with internal movement from climatically induced expansion, contraction and wind and rain forces. They also must cope with production stresses caused by heavy and changing loads, vibration and other factors encountered within diverse industries – as well as dust, bird droppings, rain-borne impurities and other airborne pollutants that can affect tanks used by industries in remote, rural and grimy urban settings, including industries such […]
