一种弯管特殊形式坡口的加工方法

介绍了一种弯管特殊形式坡口的加工方法,重点从操作控制方法、参数设置、控制流程等方面做了说明,使得这种特殊形式的坡口在有限的加工条件下得以实现.这种特殊形式坡口可以将由过渡台阶产生的负面影响(即引起的流体渐变流或急变流产生的外力和对管体的更大的冲击)转移到距离焊缝50mm之外平滑过渡,能使管道相对比较薄弱的焊缝更好地得到...

A Kind of Processing Method on Special Bevel of Bend Pipe

In this article,it introduced a kind of processing method on special bevel of bend pipe,emphasized several aspects from control method,parameter setting,control flow and so on,which can enable this type of special bevel to be realized under limited processing condition.This kind of special bevel can transfer negative influence caused from transition step(that is outside force originated from gradually varied flow or rapidly varied flow,as well as greater impact to pipe body) to 50 mm distance from weld and smooth transition,and make the thinner weld be well protected.
