2005年9月,某石油储备基地300×10~4m~3原油储罐建造工程开工,当地锅检所对全部储罐现场制造安装进行了监督检验。2006年5月,锅检所对施工单位已完成自检的T101、T103、T105、T106和T201等5台10×10~4m~3双盘浮顶储罐纵环焊缝进行第三方无损检测抽查时,发现环缝裂纹11条,纵缝裂纹28条,且多数裂纹是垂直于焊缝方面的横向裂纹。储罐内径为80m,储罐高度为21.815m,介质为原油,其密度837~872kg/m~3。主体材
In September 2005, construction of a 300 × 10 ~ 4m ~ 3 crude oil storage tank at a petroleum reserve base started. The local pot inspection agency supervised and inspected all the tank manufacturing and installation sites. In May 2006, the third party non-destructive testing of the longitudinal weld of 5 sets of 10 × 10 ~ 4m ~ 3 double-deck floating roof storage tanks, such as T101, T103, T105, T106 and T201, which the construction unit has completed self- In the spot check, there were 11 ring cracks and 28 longitudinal cracks, and most of the cracks were transverse cracks perpendicular to the weld. The inner diameter of the storage tank is 80m, the storage tank height is 21.815m, the medium is crude oil, and its density is 837-872kg / m ~ 3. The main material
