套管管端尺寸对车制偏梯形螺纹的影响

Effects of Materials Size of Plane Tube on Parameters of Buttress Thread Cutting

文章通过分析指出,偏梯形螺纹有比圆螺纹更具优势的特点,也因此在使用符合API 5CT要求的套管原料进行生产时,由于平端套管原料管子尺寸精度原因而更易产生缺陷,通过理论计算和现场实测,提出了合适的偏差范围。

The article indicates the characteristics of buttress thread compared with round thread and analyzes the defect caused by materials size of API and 5CT plane tube.According to theoretical calculation and the practical examination,it puts forward the proper error range of the materials size of plane tube.
