国家科委“六五”攻关项目——管材超声综合参数检测系统于1985年12月18日在宝鸡有色金属加工厂通过部级鉴定.该系统能进行φ10~40mm薄壁管材的超声探伤和内外径、壁厚、椭圆度,偏心量的检测.探伤时同一人工缺陷的多次检测回波幅度波动小于1dB,消除管端探测盲区,几何尺寸测量精度达0.01mm,用微机进行讯号处理,测量速度为8~20/分.这套系统的研制成功,首次在我国实现了管材综合参
National Science and Technology Commission “Six Five ” research project - pipe ultrasonic integrated parameter detection system on December 18, 1985 in Baoji non-ferrous metal processing plant through the ministerial level identification.The system can be φ10 ~ 40mm thin-walled tube ultrasonic flaw detection And the inner and outer diameter, wall thickness, ovality, eccentricity detection.When the detection of the same artificial defects multiple detection echo amplitude fluctuation is less than 1dB, eliminating the pipe end detection blind spot, the geometric measurement accuracy of 0.01mm, the signal processing using a computer , The measurement speed of 8 ~ 20 / min.This system was successfully developed, for the first time in our country to achieve a comprehensive pipe parameters
