摘要
通过2个在一定腐蚀环境下工作的黄铜管道部件失效断裂的案例,分析黄铜管道部件的特点及失效原因,有助于提高黄铜管道的运行水平。结果表明:失效件均在承受一定应力的腐蚀环境中服役,从而引发应力腐蚀开裂。
Through two cases of failure and fracture of brass pipe parts working in a certain corrosive environment,the characteristics and failure reasons of brass pipe parts are analyzed,which is helpful to improve the operation level of brass pipe. The results show that the failure parts are all in service in corrosive environment under certain stress conditions,so as to stress corrosion cracking.
