，比橢圓開封頭節約，平板封頭用材多。因此，從強度、結構和製造方麵綜合考慮，采用橢圓形封頭較為合理。

容器支座有鞍座,圈座和支腿三種,用來支撐容器的重量。鞍式支座是應用較guangfandeyizhongwoshizhizuo。congyinglifenxikan，chengshoutongyangzaiqiejuyoutongyangjiemianjihexingzhuanghechicundeliangcaiyongduogezhichengbicaiyonglianggezhichengyouyue

容器和真空操作的容器。腿式支座簡稱支腿，因這種支座在與容器殼壁連接處會造成嚴重的局部應力，故隻適合用於小型設備（DN1600，L≤5m）。綜上考慮在此選擇雙個鞍式支座作為儲罐的支座。
