The uncertainties of governing variables, such as the physical properties of soil, cast iron, water pressure and corrosion patterns, in pipe failure risk assessment are considered. Using probabilistic physical modelling, the lifetime probability of failure is derived and a time-dependent sensitivity ...

Pulling corrosion-resistant, thermoplastic pipe into a corroded steel pipeline is proving to be more technically viable and cost effective than conventiona... RB Stonesifer,R Mcintosh,A Ekelund 被引量: 1发表: 0年 Logbook My other Mini, Oscar, the Java Green 1979 car, has a stripped-out rac...
A methodology was proposed to identify critical factors for initiating a through-wall crack in cast iron water pipe considering the impact of fatigue. A sensitivity analysis was conducted with relevant factors, and the relative impact of those factors to cause a premature failure was assessed. The...
Our numerical findings suggest that the proposed simplified numerical approach may be used to determine whether a corroded cast iron pipe would leak before break provided that the corrosion condition of the pipe and the relevant material properties are available. However, the window of time for leak...
A pilot pipe-loop system was constructed using 100-year-old unlined cast-iron pipes. The composition and structure of the corrosion scales were characterized, and iron release was investigated for various water quality conditions. Results showed that iron release could be reduced over time by ...
PROBLEM TO BE SOLVED: To shorten time required for removing operation of deposits and graphitized corroded part on cast iron pipe outer surfaces.SHOBU MITSUNORI菖蒲 光徳YAMAMOTO MASAYUKI山本 雅之MATSUURA EIJI松浦 英次
PURPOSE: To obtain a corrosion detecting method by which the corrosion of a buried cast-iron pipe can be easily detected from the ground surface and, at the same time, the future progress of corrosion can be predicted.KAJIYAMA FUMIO梶山 文夫...
