  • Cause of Boiler Tube Failures - Chicago Tube & Iron

    During periodic shutdowns of the boiler unit, tube failures can occur. Quite often they are related to dew point corrosion, an insidious condition that can penetrate up to 0.50" of steel per year. Thin walled tubes that normally last 10 years can become badly pitted during shutdown, and replacement tubing becomes an unanticipated expense.Get Price
