Ductile iron pipe is generally acknowledged as the best choice for conveying portable/sewage water under pressure. It has many fine features in terms of wall thickness, tensile strength, elongation, anticorrosion, service life, installation and so on comparing with traditional pipeline products. In 1922, cement mortar lining was firstly used to protect the interior wall of pipes and greatly improved the quality of water. The first ductile iron pipe was experimentally developed in 1948.
