Gray cast-iron water pipe metallurgy
The results of a metallographic study of grey cast iron water pipes are reported. These pipes had been installed between 1885 and 1973 in eight different water systems. Each pipe had been extracted during scheduled maintenance or failure repairs to provide data for a larger study to produce a methodology for determining the residual life of grey cast iron pipes. This metallographic study was co...
متن کاملA Comparison of the Results of the Numerical Analysis and the Physical Behavior of a Pipe Buried in Reactive Clay
Buried water and gas pipe systems form part of critical infrastructure providing essential services to the community. In many global population centres including in Australia, this vital infrastructure has been installed several decades ago, and dealing with frequent pipe failures become a major problem. There are clear evidences that pipe failures significantly depend on pipe strains induced b...
متن کاملThree dimensional mapping of corrosion pits in cast iron pipe using the remote field effect
The remote field effect is an electromagnetic method for inspecting pipes and tubing. It has recently been commercialised as a technique for inspecting gray cast iron and ductile iron water mains. However, commercial tools provide information on pits depths in the pipe and overall wall loss. Models of the mechanical behaviour of cast iron pipe also require information on pit width and length. T...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Failure modes and mechanisms in gray cast iron pipe
Failures in cast iron water mains are more complex and diverse than is widely understood in the industry. This paper discusses the modes and causes of pipe failures that have been encountered during a three year investigation by the National Research Council Canada. In addition to corrosion, manufacturing defects, human error and unexpected levels of pipe loading all play a role in the large nu...
