标准编号：ISO 10893-7:2019

中文名称：钢管的无损检测 第7部分：用于缺陷探测的焊接钢管的焊缝数字射线探伤

英文名称：Non-destructive testing of steel tubes — Part 7: Digital radiographic testing of the weld seam of welded steel tubes for the detection of imperfections

发布日期：2019-02

标准范围

本文件规定了通过计算机射线照相（CR）或数字探测器阵列（DDA）射线照相对自动熔焊钢管纵向或螺旋焊缝进行数字射线照相X射线检测的要求，以检测缺陷。本文件规定了验收水平和校准程序。它也适用于圆形空心截面的测试。注:作为替代方案，基于胶片的射线照相X射线检测见ISO 10893-6。

This document specifies the requirements for digital radiographic X-ray testing by either computed radiography (CR) or radiography with digital detector arrays (DDAs) of the longitudinal or helical weld seams of automatic fusion arc-welded steel tubes for the detection of imperfections. This document specifies acceptance levels and calibration procedures.It can also be applicable to the testing of circular hollow sections.NOTE As an alternative, see ISO 10893-6 for film-based radiographic X-ray testing.
