    Analysis and Suggestion on Application of Demestic Automatic NDT Equipment for Seamless Steel Tube

    • 摘要: 簡述國內(nèi)無縫鋼管自動探傷設(shè)備的發(fā)展現(xiàn)狀，指出各類自動探傷設(shè)備的優(yōu)缺點，并提出建議。分析認(rèn)為：將超聲波相控陣探傷應(yīng)用于自動探傷時，需要解決超聲波能量重復(fù)發(fā)射、多方向超聲波干擾、報警閘門位置與幅度設(shè)置等問題；自動渦流探傷設(shè)備在多頻檢測、信號處理軟件分析方面有待優(yōu)化；自動漏磁探傷設(shè)備若要檢測壁厚大于20 mm的無縫鋼管，則需要在磁化（線圈）設(shè)備的能力或檢測線圈的結(jié)構(gòu)參數(shù)方面進行優(yōu)化；應(yīng)用數(shù)字化自動射線探傷設(shè)備時，有必要對多射線機頭進行設(shè)置。

       

      Abstract: The present development of automatic NDT equipments for seamless steel tube in China is briefed, advantages/disadvantages of different types of automatic NDT equipments are introduced and suggestions are made.According to the analysis, when ultrasonic phased array is applied to automatic NDT, the following problems shall be tackled, including repetitive emission of ultrosonic energy, interference of ultrasonics from different directions, as well as the setup of the position and amplitude of the alarm thresholds.As for automatic eddy-current testing equipment, the muti-frequency testing and the signal processing software shall be optimized.If an automatic magnetic flux leakage equipment is to be used on seamless steel tube with wall thickness bigger than 20 mm, the capability of the magnetization (coil)device and the structure and parameters of the testing coil shall be optimized.When a digitized automatic radiographic testing equipment is to be applied, it is necessary to set up the multi-ray machine nose.
