| Abstract: | In addition to cracks resulting from welding in boiler and pressure vessels, there are also corrosion cracks due to corrosive environment. Affected by tensile stress together with corrosion medium, cracking phenomenon in equipment occasionally happens. In the light of periodic inspection to the in service equipment, the cracking behavior of steel material under various corrosive environment, affecting factors, preventing measures and inspection points are summarized, suggestions and recommendations are raised. |
