Cost of corrosion/wear in Indian pulp and paper industry – a case study

Abstract

A systematic survey of the cost of corrosion and wear has been carried out in a major pulp and paper plant in India. It is shown that the annual direct cost of corrosion and wear in the plant under consideration is £20 000. By extrapolation, the annual cost of corrosion in the entire pulp and paper industry in India is estimated to be £1·5 million. It is further shown that opting for an alternative, corrosion resistant material such as duplex stainless steel in the bleaching unit alone could lead to annual savings of almost £130 000.
