壓力(li)容器主要(yao)是(shi)壓力容(rong)器圓柱形(xing)，少(shao)數是(shi)球形(xing)或其它形(xing)狀。筒(tong)形(xing)壓力容(rong)器一般由筒(tong)體、封(feng)頭、接(jie)管、凸緣等部分和部件組成，工作(zuo)壓力越(yue)大，筒(tong)壁應越(yue)厚。

壓(ya)力(li)容(rong)(rong)(rong)(rong)器(qi)(qi)的(de)分(fen)類(lei)(lei)：　壓(ya)力(li)容(rong)(rong)(rong)(rong)器(qi)(qi)的(de)分(fen)類(lei)(lei)方法很多，按照不同的(de)方法可(ke)(ke)以(yi)有(you)不同的(de)分(fen)類(lei)(lei)：制(zhi)造(zao)分(fen)類(lei)(lei)：可(ke)(ke)分(fen)焊接(jie)容(rong)(rong)(rong)(rong)器(qi)(qi)、鍛造(zao)容(rong)(rong)(rong)(rong)器(qi)(qi)、鉚接(jie)容(rong)(rong)(rong)(rong)器(qi)(qi)、鑄造(zao)容(rong)(rong)(rong)(rong)器(qi)(qi)和組(zu)合容(rong)(rong)(rong)(rong)器(qi)(qi)五種。按材料分(fen)類(lei)(lei)：有(you)鋼制(zhi)容(rong)(rong)(rong)(rong)器(qi)(qi)、有(you)色金屬(shu)容(rong)(rong)(rong)(rong)器(qi)(qi)和非金屬(shu)容(rong)(rong)(rong)(rong)器(qi)(qi)。按壁(bi)厚分(fen)類(lei)(lei)：可(ke)(ke)分(fen)薄壁(bi)容(rong)(rong)(rong)(rong)器(qi)(qi)和厚壁(bi)容(rong)(rong)(rong)(rong)器(qi)(qi)兩(liang)種。按形狀分(fen)類(lei)(lei)：

有(you)球形(xing)容(rong)器(qi)(qi)、圓(yuan)(yuan)筒形(xing)容(rong)器(qi)(qi)、圓(yuan)(yuan)錐形(xing)容(rong)器(qi)(qi)、按(an)承壓(ya)方式分類：有(you)內壓(ya)容(rong)器(qi)(qi)和外壓(ya)容(rong)器(qi)(qi)。按(an)設計(ji)壓(ya)力劃分：低壓(ya)容(rong)器(qi)(qi)(代(dai)(dai)號L) 0.1MPa≤p﹤1.6MPa中壓(ya)容(rong)器(qi)(qi)(代(dai)(dai)號M) 1.6MPa≤p﹤10MPa高壓(ya)容(rong)器(qi)(qi)(代(dai)(dai)號H) 10MPa≤p﹤100MPa超高壓(ya)容(rong)器(qi)(qi)(代(dai)(dai)號U) p≥100MPa
