CNBM Ductile Iron Castings Sector is a leading manufacturer and supplier of high quality ductile iron pipe, pipe fittings and manhole covers in China.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. Since 1958, Zinc coating and bitumen painting have been using successfully to prevent the corrosion of water mains.CNBM mainly supply DN80~DN2200mm, K7/K8/K9/K
