摘要
TOFD检测技术由于具有检测结果可靠性好、缺陷检出率高、定量精度高、检测过程方便快捷安全环保等优点,在球罐的应用也日趋增多,本文重点介绍了TOFD检测技术下丙烷球罐施工的难点,通过对球罐施工中组装几何尺寸控制、焊接工艺把控、检测方法优化选择、检测盲区处理、检测时机选择等质量控制措施,取得了良好的效果,确保了丙烷球罐的质量。
Because of advantages of detection results of good reliability, high defect detection rate, high precision,convenientd etection process, safety and environmental protection, TOFD detection technology has been aplicated more and more in spherical tank. This paper focused on the difficulties of propane tank construction with TOFD detection technology. By quality control measures of the assembly dimension control, welding process control,optimization of detection method, processing of detection bliand area, detection of timing, etc., excellent results was achieved and the quality of spherical tank was ensuerd.
