压力容器X射线探伤中内外有效长度的计算与划线方法

Calculations and Lineation Methods of the Internal and External Effective Lengths of Pressure Vessels in X-Ray Flaw Detection

推导出了压力容器制造中,进行环缝X射线探伤时的筒体内外弧长计算公式,并列出了常用筒体X射线探伤的划线尺寸。

The formula of calculating the internal and external arc lengths of cylinders was derived in X-ray flaw detection for circumferential weld seams in pressure vessel fabrication, and the common lineation sizes of X-ray flaw detection were listed.
