Detail Information
Ductile iron pipe for the municipal water and wastewater distribution and transmission markets, industrial, and power markets including fabrication for treatment plants and pump stations.
Specification of Ductile iron pipe:
The standard of pipe: ISO 2531:1998, EN 545:2002, EN 598.
Pipe class: K9, C40, C30, C25, etc.
Diameter: DN80-DN2600 mm
Pipe jointt type: push-on joint, K type joint, self-restrained joint.
Effective length: 6m for bulk shipment and 5.7m or 5.5m for container shipment.
Lining and Coating:
Internal lining: cement mortar lining as per ISO 4179.
Zinc coating: at least 130g/m2 as per ISO 8179.
Bitumen painting: at least 70um as per ISO 8179.
The pipe coating can be customized, such as zinc-aluminum alloy, PU, etc.
Rubber Gaskets: NBR, natural rubber, SBR or EPDM as per ISO 4633.
Advantage: High strength, lighter than gray iron, good corrosion resistance, no furring, small flow resistance, easy fixing, long lifetime.
Chemical composition(%):
C: 3.5 - 4.0.
Si: 1.9 - 2.6.
Mn:0.15 - 0.45.
P: <0.06.
S: <0.02.
Mechanical properties
Tensile strength: ≥420Mpa.
Yield strength: ≥300Mpa.
Hardness: ≤230HB.
Elongation(%): DN80 - 1000 ≥10 DN1200 - 2200 ≥7
Process and testing:
1.Induction furnace and treated metal (Chemical analysis of raw material, spheroidizing & Nodularity).
2.Casting (Visual check and weight check).
3.Heat treatment (Microstructure).
4.Hydrostatic test (Pressure test).
5.Dimensional checks (Checking pipe length and joint, OD, wall thickness, appearance).
6.Zinc spraying (Thickness testing).
7.Lining and coating (100% visual check, thickness testing randomly).
8.Marking and packing (100% visual check).
