K9 Class Weld Flanged Ductile Iron Pipe Structure Round For Water Supply
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:
The nominal thickness of the cement mortar lining and its tolerance shall be as given in Table 4. When measured in accordance with 6.9, the lining thickness shall be within the specified tolerance.
The surface of the cement mortar lining shall be uniform and smooth. Trowel marks, protrusion of sand grains and surface texture inherent to the method of manufacture are acceptable. However, there shall be no recesses or local defects which reduce the thickness to below the minimum value given in Table 4. The grinding of the lining in order to remove the top surface of the internal layer is permitted provided the finished lining complies with all requirements .
Fine crazing and hairline cracks associated with cement rich surfaces may appear in dry linings. Shrinkage cracks inherent to cement-bound materials may also develop in the dry linings. After curing of the lining and under normal storage conditions, the crack width and the radial displacement (disbondment) shall not exceed the values given in Table 4.

Cement mortar linings at pipe ends may have a chamfer of maximum length 20 mm.
2. Coating of the joint areas
The coating shall uniformly cover the whole surface; it shall have a smooth regular appearance and be free from defects which may affect its function.The minimum coating thickness shall be such that the coating complies with 5.8. When measured according to 6.8, the coating thickness shall be not less than the minimum thickness given in the quality plan of the manufacturer.
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.
