Long-term corrosion loss data for a variety of metals, including ferrous metals, buried in soils were reported in Romanoff (1957) and have often been quoted in the literature. There have been few investigations of the long-term trending of the data. Herein it is shown that the corrosion behaviour of ferrous metals buried in the ground follows a bi-modal trend with time. This trend is observed for a variety of ferrous metals in many different natural environments. Similar trends have been reported also for other exposure environments. Importantly, it indicates that the corrosion process changes over time. This is illustrated for corrosion mass loss and corrosion penetration for a variety of data sets drawn from Romanoff (1957).

The corrosion of old buried cast iron water mains is a problem for the Australian Water Industry. To better manage their assets the industry requires a way of predicting the remaining service life of their pipes. In order to do this a predictive model of long-term corrosion loss with time is required. This paper describes ongoing work being conducted at The University of Newcastle to develop corrosion loss models for cast iron pipes in soils, as a function of exposure time and soil environment. A preliminary corrosion model was calibrated in a previous work, using a limited set of data collected from recent field work. This data base was extended in the current work by including data (of maximum pit depth and some soil properties) from historical condition assessments within the Hunter Water network. Previous studies by the authors (and others) indicate the significance of soil moisture content on the long-term corrosion loss and rate. At most sites soil moisture was only measured at a single point in time (or not at all), so the long-term average value of soil moisture (required for model calibration) was uncertain. To better estimate the average long-term soil moisture content, a simple climate-soil moisture model was developed. This paper presents the collected field data, describes the method for estimating long-term moisture content and presents the updated model calibration based on the additional data.

The external corrosion of buried cast iron water mains is a significant problem for the Australian Water Industry. To improve maintenance and replacement strategies for these mains the industry requires a method to estimate their remaining service lives. Predictions of long-term corrosion losses, pit depths and pitting extents are therefore required. A conceptual model for the prediction of long-term corrosion has been developed and the external soil conditions influencing corrosion were identified in a previous study. To calibrate the model, long-term data of corrosion (average loss and maximum penetration) and associated soil parameters for pipes in service is required. Field data has been collected at 18 condition assessment sites and two pipe replacement sites within Hunter Water Corporation's network. This paper presents the field observations and measurements taken from these sites, the model calibration procedure and results of the calibration. The results show that the long-term maximum corrosion penetration increases with increasing soil wetness (measured using degree of saturation) over the observed range of degree of saturation (0.5 to 0.86). The initial model calibration produced model parameters for cast iron pipes buried at standard depths in relatively homogeneous, low-permeability, soils with degrees of saturation equal to 0.57, 0.66, and 0.76.
