在生产石油化工设备中,塔器和容器占有较大的比例,其结构形式一般均为圆筒形。由于这些容器所承受的容量、介质和工作压力不同,所以除使用的钢材质量及钢板厚度有所区别外,其高度(长度)和直径也是多种多样的。因此,这类容器在制造时很难使用专用机械组装(制造厂习惯上称之为非标准生产),生产效率低,周期长。过去我厂在制造容器时,不管是 In the production of petrochemical equipment, tower and container occupy a large proportion, the structure of the form are generally cylindrical. Due to the different capacities, media and working pressures these containers are subjected to, the height (length) and diameter of the containers vary, depending on the steel used and the thickness of the steel. As a result, containers of this type are hard to use in the manufacture of specialized mechanical assemblies (which are customarily referred to by manufacturers as non-standard production), which are inefficient and have a long cycle. In the past I plant in the manufacture of containers, no matter
