BSEN545 ISO2531 Flanged Ductile Iron Pipe Internal / External FBE Coatings

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.
Internal Lining.

All flanged joints for ductile iron pipes and components shall be designed in compliance with the requirements, If the design has been tested and documented by the manufacturer and successfully used for a minimum of 10 years, the performance of a type test as specified is only required for significant changes in design which could adversely affect the performance of the joint. When flanges are involved, there shall be a type test for at least one DN for each of the groupings given. The PN to be tested is the highest PN existing for each flange design. One PN 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. f, 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.

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.
