The ISO2531 EN545 Ductile Iron pipe possess the essence of iron and the performance of steel.
As a new kinds of pipes, it's excellent performance are: excellent mechanical properties, easy SSAW steel pipe |
installation, low construction project cost, high reliability, good corrosion resistance and long
operating life etc.

Ductile cast iron pipe conforms to ISO2531and EN545:2002, including the rubber ring in according
to ISO4633, the coating of the pipe is the internally cement mortar lining and externally rich zinc
paint and bituminous paint. The zinc spraying conforms to ISO8179, the minimum zinc spraying per DSAW steel pipe |
square meter is 130g, and the thickness of bitumen paint is not below70 μm. And the cement
mortar lining is in compliance with ISO4179, the thickness of which is as followed list.API steel pipe |
