was the introduction of ductile iron pipe in the late 1960s. Ductile iron differs from cast iron in that its graphite form is spheroidal, or nodular, instead of the flake form found in cast iron . This change in graphite form is accomplished by adding an inoculant, usually magnesium, to molten iron of Draft - University of Torontooperation. Three typical flexible underground pipe materials, namely, steel, ductile iron (DI) and polyvinyl chloride (PVC) have been considered. The most dominant phase of the life cycle is pipe manufacturing and fabrication process, resulting in large amounts of CO 2 emissions.

Problems and Solutions The Future of Water and Sewer Systems The Factors of Change Background Key Pipe Characteristics Discussion of Benefits For years we have seen the phenomenon where many sanitary sewer flows become septic and develop hydrogen sulfide gas, which may eventually be converted to sulfuric acid.

Results of the research show that while PVC pipe may have initial cost benefits, Ductile Iron Pipe is the more cost -effective material over the pipelines service life . Of note, there is a sharp rise in a cost break-even graph analysis of the two pipe materials due to the shorter service life of PVC pipe , which then requires replacement. Protecting a Pipeline Against Corrosion--A Cost StudyCorrosion Protection Options What About The Costs? Costs Over The Pipeline's Projected Life Life cycle cost analysis involves taking a realistic look at all costs associated with achieving the expected service life of a major investment like this pipeline under study. The method provides a comparison between alternative solutions to determine which is truly the more cost effective.

What is the likelihood the asset will fail? 2. What are the consequences if the asset fails? These questions establish two important asset valuations the probability of failure (PoF) and the consequence of failure (CoF). Together, these factors can help rank assets and create meaningful arguments for capital improvement.

The ductile cast iron structure has a high elastic deformability and a high resistance to crack initiation it results in excellent impact resistance. The cast iron pipes are perfectly suited to transport conditions over long distances (truck, train or ship), handling conditions on sites and to different types of backfilling. What's the life of a ductile iron pipe?What's the life of a ductile iron pipe?Ductile iron, like PVC, has been used for water and wastewater infrastructure for about 60 years. For this study, ductile iron pipe is assigned a 50-year service life based on failure data of DI pipes and the fact that new ductile iron pipes have much thinner walls than older iron pipes and lack independent dig-up and pipe material testing studies.Study Takes Comprehensive Look at PVC Life Cycle Life Cycle Cost Analysis Ductile Iron Pipe Research
