Flanged Ductile Iron Pipe:
Flanged ductile iron pipe with a range of DN80 to DN 2600.belongs to 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.The lengths of flanged pipes shall be as given. Other lengths are available by agreement between the manufacturer and the purchaser.

By agreement between manufacturer and purchaser, the 0,2 % proof stress (Rp0,2) may be measured. It shall be not less than:
¾ 270 MPa when A ³ 12 % for DN 80 to DN 1000 or A ³10 % for DN > 1000;
¾ 300 MPa in other cases.
Compressive strength of the cement mortar lining
The compressive strength shall be the arithmetic mean of six compressive strength tests performed on three prism samples after 28 days of curing.
The compressive strength shall be determined by a performance-test in accordance with EN 196-1, except that:
Packing: in wooden box or pallet, or in bulk
Shipment: in bulk or container
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. 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.
