first railway bridge to use stainless steel components project in Tamil Nadu
February 11, 2019
Indian Railways is planning to replace the 104-year-old British era Pamban bridge with country's first vertical-lift bridge. The cost of two-kilometre-long new Pamban Bridge is estimated at Rs 250 crore. It may be noted that the Pamban Bridge connects Rameswaram on Pamban Island to the Mandapam railway station on mainland Indian peninsula. The bridge is located in the second most corrosive region in the world which is why corrosion related problems and the associated high repair and maintenance costs have been the centre of discussion. In order to ensure that the new bridge has a long life, Indian Railways has decided to adopt duplex stainless steel for fabrication of 4 girders of the new Pamban Bridge. Rail Vikas Nigam Limited (RVNL), Chennai, has included SS 2205 duplex stainless steel grade as an integral component for the new bridge. RVNL has floated a tender for supply of 120 MT of stainless steel, the report added. This will be the first railway bridge in India to use stainless steel structurals.
