pump sets castings, the Kolhapur and Belgaum for automotive castings, Rajkot cluster for diesel
engine castings and Batala and Jalandhar for machinery parts and agricultural implements.
Process Control Instrument Industry: Process control instruments cover wide range of
instruments and systems required for monitoring and measurement of physical, chemical and
biological properties. They are used for measurement and control of process variables like
pressure, temperature, humidity, liquid level, flow, specific gravity, chemical composition
including pH and many forms of spectrometry and spectrophotometry. The process control
instruments have become an integral part of the modern industrial activity. This industry is a key
industry which provides tools for automation. Their importance is significant in high cost, large
and sophisticated process industries like fertilizer, steel, power plant, refineries, petrochemicals,
cement and other process industries. The present technology is a microprocessor based
centralised control system.
Seamless Steel Pipes and Tubes: Seamless steel pipes and tubes are produced in different
sizes. The wide size range makes them suitable for use in number of versatile area of application.
The process of manufacture imparts strength and durability to the pipes and thus can be used for
corrosion - resisting applications. These pipes are also used for aircraft, missile and anti-friction
bearing, ordnance, etc. Ultra-high strength and corrosion-resistant properties make these perfect
for oil and gas industry, chemical industry and automobile industry. Oil sector accounts for
around 60 per cent of the total requirement of seamless pipes. Bearings and boiler sector
contribute around 30 per cent of demand. The industry is able to manufacture tubes up to 14”
Electrical Resistance Welded (ERW) Steel Pipes and Tubes: Based on the customers’
requirement, ERW steel pipes and tubes are available in various qualities, wall thickness and
diameters of the finished pipes. High performance ERW steel pipes and tubes possess high
corrosion resistance, high deformability, high strength and high toughness. These pipes are used
in fencing, lining pipes, oil country tubulars, scaffolding, water and gas conveyance, etc. There
has been tremendous increase in the production of ERW steel pipes due to higher demand in oil
and gas industry, infrastructure and automobile uses. There are a large number of units in the
Submerged-Arc Welded (SAW) Pipes: There are two types of SAW pipes namely
longitudinal and helical welded SAW pipes. Longitudinal SAW pipes are preferred where
thickness of pipe is more than 25mm and in high pressure gas pipe line. Helical welded SAW
pipes are used for low pressure applications. The cost of helical SAW pipes is less than
longitudinal pipes. There is huge demand of SAW pipes in the country due to transportation of
oil and gas and transmission of water.
Industrial Fasteners: The fastener industry in India may be classified into two segments:
high tensile and mild steel fasteners. These broadly include nuts, bolts, studs, rivets and screws.
Mild steel fasteners are primarily manufactured by the unorganized sector while high tensile
fasteners requiring superior technology are dominated by companies in the organized sector.
Automobile industry accounts for bulk of the total demand of this industry. Consumer durables
and railways are the other primary users of the high tensile fasteners. Automobile sector is likely
to drive growth in the fastener industry.
Steel Forgings: Forgings are intermediate products used widely by original equipment
manufacturers in the production of durable goods. The composition of the Indian forging
