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.
Our advantages:
There are lots of qualified managers and technicians, and a
well-trained team of after-sales service, which provides all
services of manufacture, package, transportation and installation.
We are looking forward to cooperating with friends from abroad and
