Product Description

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.
