Electric Resistance Welded Pipe that is also known as ERW pipe and it is made of strips of steel that is hot rolled and passed through forming rolls and finally welded together. It is used for usually high diameter. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel tubes are comparatively economical and possess high dimensional accuracy, and can also be produced with thinner wall thicknesses. Owing to these advantages, use of ERW steel tubes had risen steadily in recent years. However, as the properties required for steel tubes used in automobile parts have become stricter, development of a new steel tube which possesses both high strength and excellent formability has been desired. 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 tubular, scaffolding, water and gas conveyance, structural, engineering purposes, 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 large numbers of units in the SSI sector. The industry has been de licensed and is eligible for automatic approval up to 100 per cent FDI. APPLICATION: ERW Stainless Steel Pipes are extensively used for conveyance of fluids intended for critical high temperature and general. Seamless SS Tubes are used in under similar service conditions in heat transfer process equipments like boilers, super heaters, heat exchangers, condensers etc. Steel line pipe made with fusion weld zones has the strength of around 70% of the parent material used, and in this way, ERW pipe is superior ERW steel pipes find its usage in diverse fields. They are used in various structural and engineering purposes, fencing, line pipes, and scaffolding. For the purpose of oil country tubular, water and gas conveyance ERW steel pipes are widely used. There has been a tremendous increase in the use of ERW steel pipes in the sector of automobiles and in the sector of agriculture. They are equally used for drinking water in housings, in collieries for extraction of Water, Thermal Powers, Hand pumps for deep boring wells, and also as strong protection for cables by Telecom Department. ERW is used for transporting oil, gas and other vapour liquid objects and can meet the requirements of high and low pressure. MARKET SCENARIO: ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. In 2010 to 11, the Indian steel industry's demand to capacity ratio is estimated to have been at 88 per cent. However with higher capacity additions expected in 2011 to 12, 2013 to 14 and 2015 to 16, the demand to capacity ratio is expected to moderate from 2013 to 14 onwards. About 55 to 60 million tonnes of crude steel capacity additions have been announced over the next 5 years.
