管道上环绕施胶胶接接头的力学分析

The mechanical analyses to bind round coating adhesivejoint on water pipe

运用力学原理和化学知识 ,分析了应力、水等对管道胶接接头的破坏作用 ,探讨了环绕施胶方式所形成的胶接接头使用寿命较长的原因 :热应力和固化收缩应力可转化为正压应力 。

Using mechanical principles and chemical knowledge, we analyze water and stress's effects on adhesive joints and discuss the reasons for long life of bind round coating adhesive joint.The main reason is that,solidification contract stress and heat stress can change into an additional mechanical pressing force in those adhesive joints.
