标准摘要
[中文适用范围]: ISO 10893 的本部分规定了无缝钢管和焊接钢管(埋弧焊 (SAW) 管除外)的自动全周边超声波检测的壁厚测量要求。 它规定了测试方法和相应的校准程序。 注 1:完整的外围测试并不一定意味着 100% 的管表面被扫描。 注 2:该测试可以与全周边超声波测试同时进行,以检测层状缺陷(参见 ISO 10893-8),使用相同的超声波换能器来满足两种检查要求。 在这种情况下,根据 ISO 10893-8,检测的最小层压尺寸决定了用于扫描的管表面的百分比。 ISO 10893的这一部分也适用于圆形空心型材的测试。 ISO 10893 的本部分适用于规定外径等于或大于 25.4 mm、最小壁厚为 2.6 mm 的管材的厚度测量,除非另有约定。 [外文原描述]: ISO 10893-12:2011 specifies requirements for the automated full peripheral ultrasonic testing of seamless and welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for wall thickness measurement. It specifies the testing method and corresponding calibration procedures. It can also be applicable to the testing of circular hollow sections. ISO 10893-12:2011 is applicable to the thickness measurement of tubes with a specified outside diameter equal to or greater than 25,4 mm and a minimum wall thickness of 2,6 mm, unless otherwise agreed on.
