ISO2531 Standard Flanged Ductile Iron Pipe K12 Length Centrifugal Cast
Flanged Ductile Iron Pipe
Flanged ductile iron pipe is ductile iron pipe with flange at singal/double ends or with puddle flange in center, generally speakingy it including double flanged pipe, Flange spigot/socket pipe, and puddle flange pipe ect. PN10/16/40, with a range of DN80 to DN 2600.
Flanged joints shall be designed to facilitate attachment to flanges whose dimensions and tolerances comply with ISO 7005-2 or EN 1092-2. This ensures interconnection between all flanged components (pipes, fittings, valves, etc.) of the same DN and PN and adequate joint performance. Bolts and nuts shall comply, as a minimum, with the requirements of ISO 4016 and ISO 4034, property class 4.6. Where washers are required, they shall comply with ISO 7091. |
In addition, each type of flange joint shall be designed to meet the performance requirements of 5.3. |
Although it does not affect interconnection, the manufacturer shall indicate in his handbook whether his products are normally delivered with fixed flanges or loose flanges. |

Usage:
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.
