In general there occur a spring failure(low stress fracture)in the valve used for the liquid oil-gas(LOG)tank Iorry after the Spring is used three months to one year.The fracture was investigated with the help of a scanning electron microscope and X-ray diffraction tester.The experimental results showed that the fracture morphology was of the typical intergranular with secondary cracks,and in the surface of the corrosion presented lots of sulphur contents and some iron sulphide.The authors believe that the spring failue gives rise to the existing of hydrogen sulphide and water in LOG,and the failure is none other than the so called“hydrogen sulphide corrosion cracking”or“hydrogen sulphide cracking”. In order to raise the resistance against hydrogen sulphide,the surface of the spring was treated and improved by the Cu-Ni-Cr composite plating.In addition. some other problems such as the improvement on the design of the spring and mea- sures to be taken to reduce the hardness of the spring were discussed in this paper.

盛装液化石油气的槽车经用户使用一段时间后,曾数次发生安全阀弹簧断裂事故。本文借助于扫描电镜,X—射线结构分析仪等分析手段,观察了断裂弹簧的显微组织及断口形貌,分析了腐蚀产物的化学成分和结构。结果查明,弹簧的断裂是由于液化石油气中含有 H_2S 和 H_2O 所引起的硫化氢腐蚀开裂所造成的。对弹簧表面进行了防护处理,尤以Cu—Ni—Cr 复合镀层的弹簧抗硫化氢腐蚀开裂的性能最佳。本文还讨论了弹簧改进设计,降低硬度等改进措施。
