分離容(rong)器(qi)(qi)(qi):用(yong)于(yu)(yu)完成(cheng)介質(zhi)(zhi)的(de)(de)(de)(de)(de)質(zhi)(zhi)量交換、氣(qi)體凈化、固、液(ye)(ye)、氣(qi)分離的(de)(de)(de)(de)(de)容(rong)器(qi)(qi)(qi)。貯(zhu)運(yun)容(rong)器(qi)(qi)(qi):用(yong)于(yu)(yu)盛裝液(ye)(ye)體或(huo)氣(qi)體物(wu)料、貯(zhu)運(yun)介質(zhi)(zhi)或(huo)對(dui)壓力起平衡緩沖作用(yong)的(de)(de)(de)(de)(de)容(rong)器(qi)(qi)(qi)。20世(shi)紀60年始，站的(de)(de)(de)(de)(de)發展(zhan)對(dui)反應堆壓力容(rong)器(qi)(qi)(qi)提出了更高的(de)(de)(de)(de)(de)安全和技術要求，從而促(cu)進了壓力容(rong)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)進一步發展(zhan)，廣泛應用(yong)于(yu)(yu)各工業部門(men)。壓力容(rong)器(qi)(qi)(qi)內(nei)外部檢(jian)驗(yan)(yan)這種檢(jian)驗(yan)(yan)必須在停車和容(rong)器(qi)(qi)(qi)內(nei)部清(qing)洗(xi)干(gan)凈后(hou)才能進行。檢(jian)驗(yan)(yan)的(de)(de)(de)(de)(de)主要內(nei)容(rong)除包括外部檢(jian)查的(de)(de)(de)(de)(de)全部內(nei)容(rong)外，還要檢(jian)驗(yan)(yan)內(nei)外表面的(de)(de)(de)(de)(de)腐蝕磨損現象；

 壓(ya)(ya)力(li)容(rong)(rong)(rong)器(qi)(qi)按在生產工藝過程中的作用原(yuan)理，分為(wei)反應壓(ya)(ya)力(li)容(rong)(rong)(rong)器(qi)(qi)、換熱壓(ya)(ya)力(li)容(rong)(rong)(rong)器(qi)(qi)、分離(li)壓(ya)(ya)力(li)容(rong)(rong)(rong)器(qi)(qi)、儲存壓(ya)(ya)力(li)容(rong)(rong)(rong)器(qi)(qi)。壓(ya)(ya)力(li)容(rong)(rong)(rong)器(qi)(qi)檢驗(yan)除了上述檢驗(yan)項(xiang)目外(wai)，還要進行耐壓(ya)(ya)試(shi)驗(yan)（一(yi)般進行水壓(ya)(ya)試(shi)驗(yan)）。對主要焊(han)縫進行無損探傷抽查或全部(bu)焊(han)縫檢查。半球(qiu)(qiu)形(xing)封頭。一(yi)般為(wei)標準(zhun)半球(qiu)(qiu)形(xing)狀(zhuang)(zhuang)，壓(ya)(ya)力(li)容(rong)(rong)(rong)器(qi)(qi)制(zhi)造，一(yi)般不帶直(zhi)邊。應力(li)狀(zhuang)(zhuang)態好，但加工制(zhi)造困難，三類壓(ya)(ya)力(li)容(rong)(rong)(rong)器(qi)(qi)，僅用于(yu)高壓(ya)(ya)或直(zhi)徑大的容(rong)(rong)(rong)器(qi)(qi)。

 壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)主要(yao)為圓柱形(xing)，也(ye)有球(qiu)形(xing)或其他形(xing)狀(zhuang)。根(gen)據結構(gou)形(xing)式，溫(wen)州壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)，可分為多層式壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)，繞板式壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)、型槽繞帶(dai)式壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)、熱套(tao)式壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)、鍛(duan)焊式壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)和(he)厚板卷焊式壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)等。半(ban)球(qiu)形(xing)封頭。一般為標準(zhun)半(ban)球(qiu)形(xing)狀(zhuang)，一般不帶(dai)直邊(bian)。應力(li)(li)狀(zhuang)態好，但加工制造困(kun)難，僅用于(yu)高壓(ya)(ya)或直徑大的(de)容(rong)(rong)(rong)器(qi)(qi)。20世紀60年始(shi)，一類壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)，站的(de)發展(zhan)對反(fan)應堆壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)提出(chu)了(le)更高的(de)安全和(he)技術要(yao)求，從而促(cu)進(jin)了(le)壓(ya)(ya)力(li)(li)容(rong)(rong)(rong)器(qi)(qi)的(de)進(jin)一步(bu)發展(zhan)，廣泛(fan)應用于(yu)各工業部門。
