| Abstract | ||
| This research study is considered a takeover and the finish of the study of langelier saturation index. Langelier saturation index considered the best take over to show up the effect of water on metal pipes either corrosive or scale forming which was invented in 1936 by Langelier W.F. The research study discuss the method of langelier saturation index method and calculating the values of water components to get water effect water on metal piping system along with the experimental method by preparing water samples of two deferent types of metal pipelines which are Ductile iron and Carbon steel pipes for their expensive costs, high performance and commonness, the experimental method is to take 5 water samples classified as the LSI values analysis of alkalinity and calcium carbonate and then, the adjustment of pH, Total dissolved solids and temperature which are -0.2, -0.5, -1, -3, and -5 and each sample of Carbon and Ductile are submerged in a sample of water separately in a water basin (e.g sample 1 of ductile and sample 1 of carbon, submerged separately in water sample of LSI= -0.2). And this period repeated every week after checking the weight loss of Ductile and Carbon samples and checking the water characteristics according to the LSI value along the experimental duration which are eight weeks And then the accumulative weight loss for each five sample of Carbon steel and Ductile iron have found to show up the effect of LSI value against the two different samples of pipes in mg/l From then from the calculation of the accumulative weight loss that based on LSI,l the rate of corrosion equation, pipeline age, periodic maintenance and time of replacement. | ||
