一种可调式管道中心透照装置在厚壁管道对接接头γ射线检测中的应用

摘要

In this paper,An adj ustable pipe center panoramic radiographic equipment for high pressure,high temperature and thick walled pipe butt-weld joints has been developed in testing of hydro cracking unit.This equipment can effectively improve the construction efficiency and the quality of the film.%以某加氢裂化装置的高压、高温、厚壁管道射线检测为例，制作了一种可调式管道中心透照装置，该装置采用γ射线中心曝光法检测对接焊缝，有效地提高了工作效率和底片质量。
