Product Description

Two Ends Flanged 100mm Ductile Iron Pipe Internal Cement Lining External Zinc


Flanged Ductile Iron Pipe overview:

Flanged joints shall be designed to facilitate attachment to flanges whose dimensions and tolerances comply with ISO 7005-2 or EN 1092-2. This ensures interconnection between all flanged components (pipes, fittings, valves, etc.) of the same DN and PN and adequate joint performance. Bolts and nuts shall comply, as a minimum, with the requirements of ISO 4016 and ISO 4034, property class 4.6. Where washers are required,they shall comply with ISO 7091.In order to demonstrate their strength and leaktightness in service conditions, flanged joints shall be subjected to a type test. When tested as specified in 7.4, they shall show no visible leakage under the combined effects of a hydrostatic internal pressure and a bending moment as given in Table 10, where the pressure is (1,5PN + 5) bar, the relevant bending moment is obtained by addition of the bending moments due to the weight of the components and of the water in the test assembly and those due to a possible external load calculated as a function of the length of the unsupported span of the testing arrangement.A type test shall be carried out on each type of flange joint available from the manufacturer in accordance with requirement.

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.
