Ductile Cast Iron Pipe
Product Name: Ductile Cast Iron PipePlace of Origin: ChinaFeatures:1) The pipes are manufactured according to the international standard ISO2531 (E)and EN 5452) The pipes are push-in joint type, external coating zinc + bitumen painting, internallined the cement mortar or ceramic epoxy3) The gasket materials are the NR, NBR, EPDM, etc.Ductile iron pipes for water conveyance:Product standards: BS EN545:2002, ISO2531:19981) Pipes are supplied in standard length of 5.5/6.0m, short length pipes as perrespective standards can be supplied2) In addition to Class K9 pipes, HeBei Newton supplies K7, K8, K10, and K12 classesof pipes3) The thickness can be determined by the formula-e=K (0.5+0.001DN)4) PFA (allowable operating pressure) is the internal pressure, exclusive of surge,that a component can safely withstand in permanent service5) PMA (allowable maximum operating pressure) is the maximum internal pressure,including surge, that a component can withstand for a relatively short duration,when either fixed above ground level or laid and back-filled underground in order tomeasure the integrity and leak tightness of the pipe.Ductile iron pipes for sewerage application:Product standard: BS EN598:2002Quality checks at every stage of manufacturing:1) Strict selection of raw material is an indispensable requirement to produce qualityductile iron pipes and fittings. Newton endeavors to achieve `Quality right thefirst time` with strict quality control on raw material selection and procurement.2) Newton produces liquid metal suited to manufacture ductile iron pipes. The liquidmetal is further processed in induction furnaces. It is then treated with magnesiumfor modularization and transferred to the centrifugal spun casting machines.3) The pipes are heat treated, zinc coated, hydrostatically tested, tested, cementmortar lined and finished with a layer of bitumen coating.4) The in-process inspection and quality control at all points during the productioncycle is strictly maintained and documented as ISO9001 quality systems.Process and testing:1) Blast furnace (Analysis of raw materials test )2) Mg treatment (Micro & chemical composition test)3) Pipe spinning (Temperature test)4) Heat treatment (Micro structure; Flattening test)5) Zinc coating (Thickness testing)6) Dimensional checks (Thickness & Dia. testing)7) Hydraulic test (Pressure test)8) Internal lining (Thickness testing)9) External coating (Thickness test)Main technical data for ductile iron pipes:1) Product standard: ISO2531:1998, BS EN 545:20022) Class: K93) Type of joints: push-in flexible jointMechanical properties:Wall thickness:Hydrostatic test:External coating:1) Metallic zinc with finishing layer, in accordance with ISO 8179-12) Weight of the zinc layer: ≥130gsm3) Bituminous paint, in accordance with GB/T174594) Average thickness of the layer: ≥70μm5) Internal lining: cement mortar, in accordance with ISO 4179Features:
