| 摘 要： | 介绍了钢管接触式超声波检测对探头角度的选择,将钢管厚径比（T/D）分为3种情况,并分别选择探头角度.分析认为：T/D≤0.226时,采用纯横波对管体进行检测;0.226＜ T/D≤0.260时,采用变型横波对管体进行检测,最佳入射角为23.6.;T/D＞0.260时,其探头入射角应小于最佳入射角23.6..

| Abstract: | All involved in the paper is how to selec proper probe angles for the contact type ultrasonic detection system for steel pipes. According to the three pipe thickness/diameter ratios or T/D＇s, the probe angles are determined respectively. Based on relevant analysis, it is identifie（ that in case of T/D ≤0.226, pure transversal wave will be used to detect the pipe body; in ease of 0.226〈T/D≤0.260, transformed transversal wave will be used to detect the pipe body with the best angle of incidence as 23.6°; and in case of T/D〈0.260, the probe angle will be less than the best incidence angle of 23.6°. |
