螺旋縫埋弧焊管“噘嘴”缺陷測(cè)量方法探討

Discussion on Measurement Method for Peaking Defect of SAWH Pipe

摘要: 介紹了測(cè)量螺旋縫埋弧焊管“噘嘴”缺陷的兩種方法——垂直軸線測(cè)量法和平行軸線測(cè)量法，分析了以這兩種方法為基準(zhǔn)的傳統(tǒng)測(cè)量工具的不足，并改進(jìn)設(shè)計(jì)了相應(yīng)的測(cè)量工具。改進(jìn)后的測(cè)量工具將原有定性檢測(cè)改進(jìn)為定量檢測(cè)，提高了測(cè)量精度，滿足了高標(biāo)準(zhǔn)管線鋼管“噘嘴”缺陷測(cè)量的需要；與垂直軸線測(cè)量工具比較，平行軸線測(cè)量工具操作更方便，適用性更強(qiáng)。

Abstract: Elaborated in the essay are the two methods for measuring peaking defect of the SAWH pipe, i.e., the vertical axis measurement method and the parallel axis measurement method.The shortcomings of the conventional measurement tools based on these two processes are analyzed, and accordingly, modifications thereof are made.With the modified measurement tools, the conventional qualitative detection has been turned into a quantitative one.As a result, the inspection accuracy has been improved so as to meet the need for detecting peaking defect of the high-standard linepipes.And compared with the vertical axis inspection tools, those for the parallel axis process are more convenient for operation, and more applicable as well.
