| 摘 要： | 分析了钢塑复合管管端应力失效及腐蚀破坏的形成机理,讨论了管道安装施工对钢塑复合管管端的破坏性影响,论述了管端保护环对钢塑管管端进行保护的重要性和必要性。通过分析,认为钢塑管的失效源于管端,管端首先失效的原因有应力作用、腐蚀作用和现场施工的破坏。针对于此开发了适用于钢塑管沟槽连接用管端保护环,并成功应用于国内一些管道施工项目,至今运行平稳良好。

| Abstract: | In this article,it analyzed stress failure and the formation mechanism of corrosion damage to steel-plastic composite pipe end,discussed the destructive effect of pipeline installation on steel-plastic composite pipe end,expounded the importance and necessity of protection to steel-plastic composite pipe end.Through analysis,it regarded that the failure of steel-plastic composite pipe originated from pipe end,and the failure reasons include stress action,effect of corrosion and the breakage of site operation.Therefore,a kind of pipe end protector was developed,which is used to connect steel-plastic composite pipe groove.This kind of protector was successfully applied into some China domestic pipeline projects,which run well up to now. |
