Specifications:
The manufacturing process of ductile iron pipes is made by adding magnesium, calcium and other alkaline earth metals or rare metals to the raw materials of ordinary cast iron pipes. The casting process of ductile iron pipe includes continuous casting method, hot mold casting method and water-cooled centrifugal casting method. The water-cooling method is the most advanced technology in the world today. The technical performance of ductile iron with different processes
1) The standard of pipe: ISO 2531, EN545 , EN598.
2) Pipe class: K9, C40, C30, C25, etc.
3) Pipe joint: push-on joint(Tyton joint), K type joint, self-restrained joint
4) Effective length: in general, the pipe length is 6m for bulk shipment and 5.7m for container shipment.
5) Internal lining: cement mortar lining as per ISO4179
6) Zinc coating: at least 130g/m2 as per ISO 8179
7) Bitumen painting: at least 70um as per ISO 8179
8) Gaskets are NBR rubber, natural rubber, SBR rubber or EPDM rubber ring as per ISO4633
9) DN 80 - 2,600 mm
10) Process and testing:
A. Induction furnace and treated metal (Chemical analysis of raw material, spheroidizing & Nodularity)
B. Casting (Visual check and weight check)
C. Heat treatment (Micro structure)
D.Hydrostatic test (Pressure test)
E.Dimensional checks (Checking pipe length and joint, OD, wall thickness, appearance)
F. Zinc spraying (Thickness testing)
