- 射线探伤是球罐的常用探伤方法中需人力、物力最多,占用工时最长的-种方法,其透照底片要作为球罐焊缝内在质量的重要凭证而长期保存。本文简介了北京5千 m3天然气球罐的工程概况和射线探伤的特点,并就如何组织球罐施工现场的射线探伤作了全面介绍,其中包括:采用的探伤器材、球罐焊缝的划线、定位和编号、选取的曝光参数、摄片顺序、作业台班与人员的配置、透照前的准备、透照时机头的固定与移动、标记的摆放、射线防护、暗室处理、底片评定以及返修部位的划定。最后作者就如何组织好大型球罐的射线探伤谈了若干看法。
X-Ray detection is the most man-hour consumption method that is in common use for detecting spherical tank.The negatives need to preserve over a long period of time as the important evidence of the weld inherent quality of spherical tank The general situation and characters of X-Ray detection for the 5000m3spherica I tank in Peking are described, and how to orgnize the X-Ray-detection of spherical tank in situ is introduced comprehensively in this article. These items include: de-feeling apparatus.line drawing on weld. locating and numbering. explosure data selecting. photo sequence. working shifts and persons arrangement. prepairing work before detection. detection head fixing and moving during operation. mark selecting.X-ray protection. darkroom treatment. negtive.judgement and repairing location dec- ding.At last. the author gives some suggestions about how to organize the X-Raydetection for large spherical tank.1987,6(6): 14-21,24
