大型油罐底部边缘板的设计与焊接施工

Design and Welding Construction of Edge Plates at the Bottom of a Big Oiltank

大型油罐底部边缘板所受应力很大 ,并且容易腐蚀 ,罐壁与罐底边缘板连接区域容易断裂 ,严重影响油罐的安全使用 ,在设计和焊接施工中必须予以重视。分析了大型油罐底部边缘板的强度条件 ,介绍了边缘板的厚度设计、宽度设计方法 。

The edge plates of the big oiltank support great stress and is speedy eroded.The joint position between wall of oiltank and bottom of oiltank is easy ruptured.All these are dangerous factors for security use of oiltank and need to pay attention in the process of design and welding.Analyzed intension condition of the edge plates of the big oiltank and introduced means designing thickness and width of the edge plates.The means of welding construction and preventing the bottom of the big oiltank from erosion was introduced.
