The Development Of Guidelines For The Use Of Galvanized Steel Piping For The Transportation Of Water

For a number of years the steel tube and pipe industry has worked on resolving problems of product quality. These have largely been resolved and new products have been developed to take advantage of new developments. To fully coordinate market acceptance guidance on use of galvanized piping was also required. This was largely achieved locally in 2004 with the publication by the SABS of ARP 060 - Guidance on the use and application of hot dip galvanized steel piping for the transportation of potable water in South Africa. Use of this document is not easy however and a need to have a simple computer model to assist the specifier was identified. Working with a major tube and pipe manufacturer this is now being developed and this paper will provide the background to the model?s development and its intended use. There is still a need for a partner Code of Practice on the performance of galvanized piping in buried conditions and the need for this will be highlighted together with current available information.
