Flanged Ductile Iron Pipe Overview:
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 pipe shall be classified by PN number. The
pressure class of the barrel of the flanged pipes shall be equal to
or greater than a value in bar equal to the PN of the flanges. The
pressure class of the flanged pipe barrel to be used for fabricated
flanged pipe shall be as indicated in 8.2 for welded-on flanges,
screwed-on flanges and integrally cast flanges.
Standardized lengths of flanged pipe:
The lengths of flanged pipes shall be as given in following Table.
Other lengths are available by agreement between the manufacturer
and the purchaser.
| Type of pipe | DN | Standardized lengths, La |
| With cast-on flanges | 40 to 2600 | 0,5 or 1 or 2 or 3 or 4 |

Production Process:
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.
