| 摘 要： | 用16MnR钢制造的液化石油气储罐在湿H2S环境中,易发生应力腐蚀开裂.严格控制材料质量、焊后进行热处理使焊缝及热影响区的硬度低于HB200(碳钢和低合金钢),降低介质中H2S的浓度(＜10mg/L)以及定期对储罐进行检查,是防止H2S应力腐蚀开裂的有效办法.

| Abstract: | The 16MnR steel LPG tank was subject to stress corrosion cracking in wet H 2S environment. The strict control of material quality, post welded heat treatment to reduce the hardness of welds and heat affected zone to less than HB200 (carbon steel and low alloy steel), reduction of H2S in the storage media (less than 10 mg/L) and regular inspection of the tanks proved to be the most effective way to prevent H2S corrosion cracking. |
