    ISO 2531 Class K9 Ductile Iron Tube With External Zinc Spaying Bitumen Coating

    ISO 2531 Class K9 Ductile iron pipe with external zinc spaying & bitumen coating


    Description

    Ductile iron pipe is a pipe made of ductile cast iron commonly used for potable water transmission and distribution. This type of pipe is a direct development of earlier cast iron pipe, which it has superseded.
    Owing to our expertise in this domain, we are engaged in offering an exclusive array of Ductile Iron Pipes. Extensively used in different industrial units, these pipes are manufactured under the guidance of vendor’s skilled professionals using high grade raw materials in compliance with international standards. In order to ensure quality and durability, these pipes are stringently tested on various parameters.


    Ductile cast iron is kind of alloy of iron, carbon and silicon, in which graphite exists in the type of spherical, generally the size of graphite is 6-7 class, and spheriodization grade of the pipe should be controlled 1-3 class(spheroidization rate is not below 80%). Thus after spheroidization, ductile cast iron possesses the nature of iron as well as the characteristic of steel. After annealing, its microstructure contains ferrite and a little pearlite possessing excellent mechanical properties.

    Much of the production of ductile iron is in the form of ductile cast iron pipe, used for water and sewer lines. Ductile cast iron pipe is stronger and easier to tap, requires less support and provides greater flow area compared with pipes made from other materials like PVC, concrete, polyethylene or steel. Ductile Iron Pipe is the most widely-used pipeline product in water supply and water drain/sewage projects.
