Flanged Ductile Iron Pipe:
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.The lengths of flanged pipes shall be as given. Other lengths are available by agreement between the manufacturer and the purchaser.
Samples shall be taken, at the manufacturer’s discretion, either from an integrally cast sample, from a sample attached to the casting, or from a sample cast separately. In the latter case, it shall be cast from the same metal as that used for the casting. If the casting is subjected to heat treatment, the sample shall be subjected to the same heat treatment. The tensile testing machine shall have suitable holders or grips to attach to the test bar ends so as to positively apply the test load axially.
Flanged joints:
Flanged joints shall be designed such that they can be attached to flanges whose dimensions and tolerances comply with EN 1092-2. This ensures interconnection between all flanged components (pipes, fittings, valves etc.) of the same PN and DN and adequate joint performance.
Bolts and nuts shall comply as a minimum with the requirements of EN ISO 4016 and EN ISO 4034, grade 4.6. Where washers are required they shall comply with EN ISO 7091.Although it does not affect interconnection, the manufacturer shall make the information available as to whether his products are normally delivered with fixed flanges or adjustable flanges. Flange gaskets may be one of any type given in EN 1514.
The performance requirements of flanged joints shall be in accordance with EN 545.
2. Pipes with screwed or welded flanges
The performance requirements of pipes with screwed or welded flanges shall be in accordance with EN 545.
3. Chemical resistance to effluents
Except for components intended only for the transport of rainwater, long-term performance of pipes, fittings and joints shall be demonstrated by six-month exposure tests to an acid solution and to an alkaline solution. Their field of use is given.
After six months of testing, the following conditions shall be met:
All other combinations of coatings may be tested according to the same procedure; the values of pH may be modified in order to demonstrate long-term behaviour in different environments.
Packing: in wooden box or pallet, or in bulk
Shipment: in bulk or container
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.
