8-40x1800-3000xLmm

JNSSteel plates are mainly used in steel chimneys, flue dust collectors, and other indoor steel structures that require resistance to atmospheric corrosion. In boilers that burn heavy oil or coal, the combustion gas often containsSO2、SO3，SO3It can significantly increase the sulfuric acid dew point of gas containing water vapor, so that sulfuric acid condenses at the low temperature part of the boiler, causing sulfuric acid dew point corrosion.
