According to these, the paper put forward some countermeasures : select low carbon steel or low metal alloy steel with lower intensity, like 20r steel ; while welding, adopt strict craft measures with lower welding heat to input ; after jointing, proceed the whole hot dissolving on time ; control each welding joint with hardness hb 185 ; add 0. 25 % water into the liquid ammonia as decay eclipse ; enhance checking in operation, repairing equipment in time through regular interior and exterior checking
針對上述原因提出了防止氨冷器類臨氨壓力容器產生應力腐蝕裂紋的對策:選用強度稍低,但抗裂性較好的低碳鋼和低合金鋼,如用20r鋼製造;焊接時應採用嚴格的工藝措施和較低的焊接熱輸入量;焊后應及時進行整體消除應力熱處理;控制焊接接頭各區硬度hb 185 ;在液氨中添加0 . 25 %的水作為緩蝕劑;在運行中加強檢查,及時進行停車檢修時的內外部檢查和定期檢驗。The welding speed have evident effection on weld depth and weld width, when welding speed is added, both weld depth and weld width will decrease, for the inputed heat per time is limited
焊接速度對焊縫厚度和焊縫寬度有明顯的影響,當焊接速度增加時,焊縫厚度和寬度都大為下降,這是因為焊接速度增加時,焊縫中單位時間內輸入的熱量減少。
