This unique property enhances dramatically the durability of ductile iron pipes and that is the reason why they are increasingly being selected in modern infrastructure. Quality of the raw materials, the pipe’s manufacture, and the environment in which the pipe is to be installed are significant factors which adversely affect the life span of the pipe. The ductile iron pipes are said to be highly durable and if correctly installed can last for as long as in excess of 100 years which is particularly good for the supply of potable water as well as for the sewage systems and other industrial applications. These factors of longevity should be appreciated by the engineers and project managers so that their decisions result in reliable and efficient pipeline systems.
