| Abstract: | Corrosion case history of a stainless steel compensator in a heating system of a city were analized with field survey and laboratory tests.The temperature of the compancator well was rather high.Water in the well was polluted seriously with higher Cl - and SO 2- 4 content.The condition of high temperature and humidity is very favourable for multiplying and growing of bacterial.Hence the corrosivity of the water in the compensator well is very severe.The result indicates that 304 stainless steel compensator suffered from intergranular corrosion,pitting corrosion,stress corrosion,biocorrosion in the high temperature polluted water in well. |
| Keywords: | heating system 304 stainless steel compensator corrosion |
