液氯贮槽是氯碱化工生产装置中重要的压力容器设备,属于低频不对称交变载荷条件下工作的压力容器。我厂的液氯贮槽(位号为R104~#-2)在进行内外部检验时,发现罐体焊缝存在裂纹,需返修合格后才能继续投入使用。以下是液氯贮槽罐体焊缝缺陷的返修工艺及效果。
Liquid chlorine storage tank is an important pressure vessel equipment in chlor-alkali chemical production plant, belonging to the pressure vessel working under the condition of asymmetric alternating load of low frequency. I liquid chlorine tank factory (bit No. R104 ~ # -2) in the internal and external testing, found cracks in the tank weld, to be rework qualified to continue to put into use. The following is the liquid chlorine tank tank weld defect repair process and effect.
