摘要:
针对油气集输管道多为薄壁管、探伤面为曲面且多在野外易受环境影响等特点,对超声波检测时存在的管道缺陷漏检情况,通过在现场超声检测工艺的实践和观察,从探头、扫查方式、用于校准的标准试块和对比试块等方面来改进超声检测工艺,从而达到提高超声检测缺陷检出率的目的。研究结果对于提高油气集输管道现场焊接的超声检测质量具有一定的指导意义。
Abstract:
The majority of oil-gas gathering and transportation pipeline is thin wall, detection surface is curved surface, which locate in the open and easily be affected by the environment. The undetected defect existed in ultrasonic detection, through practicing and observing the ultrasonic detection process, it put forward to improve the ultrasonic testing process from several aspects, such as probe, scanning ways, test block and reference block for calibration and etc., in order to enhance defect detection rate of ultrasonic testing. This study will provide certain guide for improving ultrasonic detection quality of oil-gas gathering and transportation pipeline site welding.
