Ductile iron PiPes & Fittings

The largest ductile iron manufacturer on

the Indian sub-continent, Electrosteel

Castings Ltd. (ECL) first manufactured

ductile iron in 1994. ECL recognised

the performance benefits provided by

ductile irons inherent strength, impact

resistance and handleability.

Electrosteel is based in Khardah, near

Kolkata, on the east coast of India and

has created modern state-of-the-art

facilities for the manufacture of ductile

iron pipes, fittings and flanged pipe

from 80mm diameter up to 1000mm.

Electrosteels manufacturing facilities

meet all current international standards

including IS:8329, ISO2531, BS EN545

and BS EN598. Over 50% of the pipe

and fittings supplied by the Khardah

plant are destined for international

markets including Europe, the Middle

East, South East Asia and Africa.

Electrosteel in EuropeRecognising the European markets need for a competitive supplier base, Electrosteel has established subsidiary companies in UK, France and Spain. Electrosteel supplies product into many other European markets through these subsidiaries.

In order to service the UK market, Electrosteel UK provides a full service package that includes:

Comprehensive stock holding of pipes,

fittings and flanged pipe

Fast track manufacture of flanged pipe

specials

Technical advice at the design stage

Full after-sales support for the product

As part of Electrosteels strategic European business unit, Electrosteel UK is able to call on the resources and support of its sister companies.

Electrosteels modern facilities produce

high quality products in an efficient,

cost effective and environmentally-

friendly manner. Operating to ISO9001

and ISO14001 standards, Electrosteel

has adopted a strategy of full process

integration. In addition to continuous

investment in the manufacturing

process, emphasis has been placed

on investing in key stages within the

supply chain to provide greater control

of costs and increased price stability for

customers.

Areas where investments have taken

place include:

Coal mines

Coke ovens

Iron ore mines

Power generation

DUCTILE IRON PIPEAN OVERVIEW

Why ductile iron?Ductile iron (spheroidal graphite or nodular cast iron)

has replaced the use of cast iron in the manufacture of

pipes and fittings. Ductile iron has more than double

the tensile strength of cast iron (420Mpa compared to

180Mpa). Simple to joint ductile iron can also be laid

in all weather conditions without the need for selected

backfill. Its strength, high safety factor and ability

to accommodate ground movement make it the ideal

pipeline material for a wide range of applications.

Key features

High strength

High safety factor

Single rated system

Surge resistant

Tolerates ground movement

Proven ease of jointing and installation

Resistant to corrosion and chemical contamination

Extensive size range

Suitable for above and below ground applications

Applications

Raw and potable water pumping and gravity

applications

Distribution mains

Sewer pipelines, pumped and gravity applications

Drainage

Pump stations and treatment works

River crossings

Bridge crossings

Piling for ground stabilisation

QUALITY CHECKS AT EVERYSTAGE OF MANUFACTURING

Strict selection of raw materials is an indispensable requirement to produce

quality ductile iron pipes & fittings. Electrosteel endeavours to achieve 'Quality

- right the first time' with strict quality control on raw material selection and

procurement.

Electrosteel commissioned its Mini Blast Furnace (MBF) at its plant at Khardah

using TKES technology. MBF produces liquid metal suited to the manufacture

of ductile iron pipes. The liquid metal is further processed and superheated in

induction furnaces. It is then treated with magnesium for nodularisation and

transferred to the centrifugal spun casting machines.

The pipes are heat treated, zinc coated, hydrostatically tested, cement mortar

lined and finished with a layer of bitumen coating/epoxy.

The in-process inspection and quality control at all points during the

production cycle is strictly maintained and documented as per ISO 9001

quality systems.
