不锈钢热水加热器在使用中常常发生筒体破裂漏水的问题 ,本文通过材质分析、无损探伤、金相检查等实验手段对加热器筒体及焊缝分别进行分析 ,结果表明 ,造成热水器失效的主要原因是使用过程中供水加药不当 ,适量减少漂白粉 (NaC1O)的用量即可避免过早失效。 Stainless steel hot water heaters often occur in the use of the rupture of water leakage problems, this paper through the material analysis, non-destructive testing, metallographic examination and other experimental means of the heater barrel and weld were analyzed, the results show that the water heater failure The main reason is improper water supply in the process of using water to reduce the amount of bleaching powder (NaC1O) to avoid premature failure.
