Description:Features:
1) The pipes are manufactured according to the international standard ISO2531 (E)
and EN 545
2) The pipes are push-in joint type, external coating zinc + bitumen painting, internal
lined the cement mortar or ceramic epoxy
3) The gasket materials are the NR, NBR, EPDM, etc.
Ductile iron pipes for water conveyance:
Product standards: BS EN545:2002, ISO2531:1998
1) 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.
Ductile iron pipes for sewerage application:
Product standard: BS EN598:2002
Quality checks at every stage of manufacturing:
1) Strict selection of raw material is an indispensable requirement to produce quality
ductile iron pipes and fittings. Electrosteel endeavors to achieve 'Quality right the
first time' with strict quality control on raw material selection and procurement.
2) Newton produces liquid metal suited to manufacture ductile iron pipes. The liquid
metal is further processed in induction furnaces. It is then treated with magnesium
for modularization and transferred to the centrifugal spun casting machines.
3) The pipes are heat treated, zinc coated, hydrostatically tested, tested, cement
mortar lined and finished with a layer of bitumen coating.
4) The in-process inspection and quality control at all points during the production
cycle is strictly maintained and documented as ISO9001 quality systems.
Process and testing:
1) Blast furnace (Analysis of raw materials test )
2) Mg treatment (Micro & chemical composition test)
3) Pipe spinning (Temperature test)
4) Heat treatment (Micro structure; Flattening test)
5) Zinc coating (Thickness testing)
6) Dimensional checks (Thickness & Dia. testing)
7) Hydraulic test (Pressure test)
8) Internal lining (Thickness testing)
9) External coating (Thickness test)
