Protection of steel assets is a priority running into billions of dollars
 Blastline is one of the world leaders in blasting, abrasives. Blastline India is an acknowledged leader and provides accessories for protective coating industries. Blastline India boasts of major international clients who have their base in India. Jolly Lonappan, Managing Director, Blastline India Pvt Ltd, shares his views on the status of the surface coating and abrasives industry in India.
Abrasive blasting is a cost effective procedureAbrasive blasting is a time-tested method of removing rust, old paint, foreign particles and other surface contaminations. This helps to achieve the right profile to ready a surface for coating. Abrasive blasting is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants. A pressurised fluid, typically air, or a centrifugal wheel is used to propel the blasting material. The abrasive blast cleaning was first introduced by the Greeks who were the pioneers in the marine industry as we know it today, maintained a large fleet of vessels for transportation between their numerous islands. Subsequently, it was established as the most cost-effective and efficient cleaning procedure for coating applications. There are several variants of the process, such as bead blasting, sand blasting, soda blasting, and shot blasting.
Investment in infrastructure largely goes for steelIn every major project, whether it is an oil refinery, shipbuilding, petrochemical plant, pipeline systems or government infrastructure, 80 per cent of the investment is used to buy steel. So, safe-guarding such investment basically boils down to the protection of these infrastructures, which in turn, demands protection of steel. “Surface coating is nothing but asset protection as much as protecting steel from corrosion. Presently almost 5 per cent of the GDP in every nation is used for corrosion protection and the costs run into billions of dollars,” observes Mr Lonappan
