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.
