Ductile Iron Pipes

Features:

1) The pipes are produced with good straightness, even wall thickness, remarkable

mechanical prosperities and firmly sticking internal and external coating layer

2) Flexible push-in joint and rubber gasket are used resulting in convenient

installation of pipelines

3) The pipes are manufactured according to the international standard ISO2531 (E)

and EN 545

4) The pipes are push-in joint type, external coating zinc + bitumen painting, internal

lined the cement mortar

5) The gasket materials are the NR, NBR, EPDM, etc.



Ductile iron pipes for water conveyance:

Product standards: BS EN545:2002, ISO2531:1998

) Pipes are supplied in standard length of 5.5/6.0m, short length pipes as per

respective standards can be supplied

2) In addition to Class K9 pipes, Electrosteel supplies K7, K8, K10, and K12 classes of

pipes

3) The thickness can be determined by the formula-e=K (0.5+0.001DN)

4) PFA (allowable operating pressure) is the internal pressure, exclusive of surge, that

a component can safely withstand in permanent service

5) PMA (allowable maximum operating pressure) is the maximum internal pressure,

including surge, that a component can withstand for a relatively short duration,

when either fixed above ground level or laid and back-filled underground in order to

measure the integrity and leak tightness of the pipe.
