Puddle Flange Pipe Flange Spigot Pipe Special Coating BSEN545
Flanged Ductile Iron Pipe overview:
Flanged ductile iron pipe with a range of DN80 to DN 2600.belongs
to 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.
There shall be a type test for at least one DN for each of the
groupings given in Table. One DN is representative of a grouping
when the performances are based on the same design parameters
throughout the size range. If a grouping covers products of
different designs and/or manufactured by different processes, the
grouping shall be sub-divided. If, for a manufacturer, a grouping
contains only one DN or PN, this DN or PN may be considered as part
of the adjacent grouping provided that it is of identical design
and manufactured by the same process. The type tests shall be
carried out in the configuration of maximum design radial gap
between the omponents to be jointed (smallest spigot together with
largest socket).

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
home creating a brighter future.
