Aimed at providing consulting engineers and contractors with a alternative to how an existing ductile iron design would compare with fabricated carbon steel, Barnard says it can demonstrate that, in many cases, steel can provide a quicker, more flexible, and economic solution. By combining steel fittings, which require fewer joints, savings on labour and materials are difficult to ignore.
In addition, designs illustrate that the use of welded steel pipe can also remove the need for large concrete thrust blocks, which can be particularly important in remote areas where the supply of concrete may be difficult, or in urban areas where there are utility services in close proximity.
UK-based Barnard, which has recently gained several important water-industry contracts, says its designs show several advantages for using carbon steel, particularly for larger diameters. Savings will also be evident for any non-standard fittings required in water and wastewater treatment plants, especially where space is confined.
