ISO2531 ductile cast iron pipes


 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.

 | LSAW steel pipe

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 |
