ISO2531 Standard Cement Lined Pipe Ductile Iron Zinc Bitumen K9 Class

ISO2531 Standard Cement Lined Pipe Ductile Iron Zinc Bitumen K9 Class

Cement Lined Ductile Iron Pipe overview:

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. When used under the conditions for which they are designed, in permanent or in temporary contact with water intended for human consumption, ductile iron pipes, fittings and their joints shall not have detrimental effects on the properties of that water for its intended use. Ductile iron pipeline systems, including pipes, fittings, accessories and joints, consist of various materials. When used for conveying water intended for human consumption, the materials in contact with the water shall meet the relevant requirements of the national standards or regulations in the country of use with respect to effect on water quality.

Specifications:

1) The standard of pipe: ISO 2531, EN545 , EN598.

2) Pipe class: K9, C40, C30, C25, etc.

3) Pipe joint: push-on joint(Tyton joint), K type joint, self-restrained joint

4) Effective length: in general, the pipe length is 6m for bulk shipment and 5.7m for container shipment.

5) Rubber gasket materials shall conform to the requirements of ISO 4633 for water applications. When materials other than rubber are necessary (e.g. high-temperature flanged joints), they shall conform to the appropriate International Standards.

Mechnical behavior:

Usage:

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.
