Product Description

EN598 545 ISO2531 Restrained Joint Ductile Iron Pipe Corrosion Resistance


Self-Restrained joint ductile iron pipe:

Restrained joint in which means provided to prevent separation of the assembled joint. All restrained joints shall be 
designed to be at least semi-flexible. Produce according to the customer’s requirement.



1) The standard of pipe: EN545 , EN598.ISO 2531,

2) High strength, lighter than gray iron, good corrosion resistance, no furring, small flow resistance, easy fixing, long life time

3) Pipe class: K9, C40, C30, C25, etc.

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)

g) Lining and coating (100% visual check, thickness testing randomly)

i) Marking and packing (100% visual check)

11) The pipe coating can be customized, such as, zinc-aluminum alloy, PU, etc.

Much of the production of ductile iron is in the form of ductile cast iron pipe, used for water and sewer lines. Ductile cast iron pipe is stronger and easier to tap, requires less support and provides greater flow area compared with pipes made from other materials like PVC, concrete, polyethylene or steel. Ductile Iron Pipe is the most widely-used pipeline product in water supply and water drain/sewage projects.
