Analysis on Technological Parameters of X-ray Imaging System in Pipe Manufacturing Industry

In this article,it briefly introduced detection principle of X-ragy imaging system,analyzed and calculated several important parameters,determined the distance L1 from the X-ray source(focus) to imaging plane,and the distance L2 from the inspected workpiece's surface to imaging plane,as well as the unintelligibility U and amplification factor M.At the same time,combined with actual?measuring result,it found that the theoretical formula calculation value just provided selection method and guide direction for technological parameter.We should consider measurement error,detection speed,equipment comprehension and so on in actual application.After many time debugging,the optimal detection sensitivity was obtained,which achieves the best inspection effect.
