上海材料研究所二室受南京劳动局锅炉压力容器检验所委托,于今年5月中旬对南京烷基苯厂400m~5球罐的全部焊缝作了一次全景曝光照相,取得了一次拍摄801张胶片,灵敏度达1%的良好结果,这在国内大型球罐质量检测方面是一次创新的尝试。现将有关技术数据介绍如下: 南京烷基苯厂400m~5球罐板厚48mm,焊缝余高约4～6mm,球罐内径9.2m,焊缝长度约300m。在这
Shanghai Materials Research Institute commissioned by the Nanjing Bureau of Labor Boiler and Pressure Vessel Inspection Commission commissioned in mid-May this year, Nanjing alkylbenzene plant 400m ~ 5 spherical tank all welded joints made a panoramic exposure photography, made a filming 801 Film, the sensitivity of 1% of the good results, which in the domestic large-scale testing of spherical tank is an innovative attempt. Now the technical data are as follows: Nanjing alkylbenzene plant 400m ~ 5 ball tank plate thickness 48mm, the remaining weld height of about 4 ~ 6mm, spherical tank diameter 9.2m, weld length of about 300m. At this
