本文介绍一种无缝钢管超声波自动探伤装置。该装置具有旋转式探头盘,同时可按装四个喷水耦合探头,一次完成钢管的纵向与横向等缺陷的探测。探头盘转速1000转/分。与探头传动装置配套的有GT-1型四通道超声波探伤仪及自动报警器等,能准确探出钢管内外壁缺陷并通过声响及喷漆标记将缺陷部位自动标出。这种方法比较适宜探测厚壁大口径无缝钢管,容易实现检验过程的自动化。曾经使用这套装置现场检验了上万公尺不同规格管材,取得一定的效果。
This article describes a seamless ultrasonic ultrasonic flaw detection device. The device has a rotating probe disk, at the same time can be equipped with four sprinkler coupling probe, one at a time to complete the vertical and horizontal pipe defects detection. Probe plate speed of 1000 rev / min. Equipped with a probe transmission GT-1-type four-channel ultrasonic flaw detector and automatic alarm, etc., can accurately detect the inner and outer wall defects and pipe through the sound and paint marks the defects automatically marked. This method is more suitable for detecting thick-walled large diameter seamless steel pipe, easy to automate the testing process. This device has been used on-site inspection of thousands of meters of different specifications of pipe, and achieved certain results.
