Special Coating Double Flanged Ductile Iron Pipe Weld Type DN80 - 2000mm
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.
Specifications:
Sewer systems constructed with ductile iron components in conformity with this standard shall be leak tight at the pressures given in Table 5, depending on the way they are normally operated. This applies under all normal service conditions, including foreseeable external loads and joint movements (angular, radial and axial).
Table 5 — Pressure
Type of operation | Internal pressure bar | External pressure bar | |
| Continuous | Occasional | Continuous | |
| Gravity | 0 to 0,5 | 2 | 1 |
| Positive pressure | See PFA in Annex A | see PMA in Annex A | 1 |
| Negative pressure | - 0,5 | - 0,8 | 1 |
Leak tightness of pipeline components
Pipes, fittings, inspection chambers and manholes shall be leak tight when used under the conditions for which they are designed . When tested in accordance with 6.5, pipes and fittings for positive pressure applications shall exhibit no visible leakage, sweating or any other sign of failure.When tested in accordance with 6.6, pipes and fittings for negative pressure applications shall exhibit no visible leakage, sweating or any other sign of failure.Pipes, fittings, inspection chambers and manholes for gravity applications shall comply with the performance requirements of 5.4.

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.
