带接箍油另一端加工螺纹的加工工艺试验

介绍了加工油管螺纹的一种新的工艺线的布置方式，工艺试验表明，带接箍油管另一端加工螺纹时，其接箍对螺纹质量基本无影响，其检验项目锥度、螺距、齿高、紧密距、Ｌ１长度在均在公差允许范围内。油管带接箍后另一端螺纹的工艺方案可行。

Testing Concerning Process of Threading Non-CoupledEnd of Coupled Tubing

The layout of a new process line for tubing threading is introduced in the paper.Relevant process testing showed that when threading the non-coupled end of a coupled tubing,thread quality was negatively affected little by the coupling,and that all the items inspected,namely taper,pitch,tooth height,standoff and L4 were within the specific tolerances.The said process for threading non-coupled end of coupled tubing has been proven practical.
