摘　　要：为了减少球罐施工中无损探伤工作量和工期,经实践证明,采用^(192)Ir源并配合T2类胶片的整体探伤方案可以在JFE-HITEN610U2L低温球罐焊缝无损探伤中使用,并且底片黑度和像质计灵敏度都达到了标准要求。此方案较传统的X射线探伤方式在工期、质量、HSE管理方面更有优势。这也是新版JB/T 4730—2005《承压设备无损检测》中关于γ源探伤相关要求的成功应用。In order to reduce the workload and construction period of spherical tank non-destructive testing, the practice showed that the overall detection method with ^192Ir and T2 class film could be used in nondestructive testing of low temperature spherical tank, and film blackness and the sensitivity of image quality met standard requirements. The method had the advantage of short construction period, quality, and HSE management over the traditional X-ray detection. It was also a successful application case of requirements on the 7 ray detection in the new version of JB/T 4730--2005 ＂non-destructive testing of pressure equipment＂.
