設(she)備法蘭(lan)是容(rong)(rong)器(qi)(qi)與介(jie)質輸送管道(dao)或儀(yi)表、安全(quan)附件管道(dao)等進(jin)(jin)(jin)行(xing)(xing)(xing)連接(jie)的(de)(de)附件。又稱(cheng)壓力容(rong)(rong)器(qi)(qi)法蘭(lan)，用于(yu)連接(jie)殼體(ti)與殼體(ti)、殼體(ti)與平蓋、殼體(ti)與管板。壓力容(rong)(rong)器(qi)(qi)檢驗(yan)除(chu)了上(shang)述檢驗(yan)項目外，高(gao)壓儲氣(qi)罐廠(chang)家(jia)，還要(yao)進(jin)(jin)(jin)行(xing)(xing)(xing)耐壓試驗(yan)（一般進(jin)(jin)(jin)行(xing)(xing)(xing)水壓試驗(yan)）。對主(zhu)要(yao)焊(han)縫進(jin)(jin)(jin)行(xing)(xing)(xing)無損探傷抽(chou)查(cha)或全(quan)部(bu)焊(han)縫檢查(cha)。壓力容(rong)(rong)器(qi)(qi)內(nei)外部(bu)檢驗(yan)這種檢驗(yan)必須在停車和容(rong)(rong)器(qi)(qi)內(nei)部(bu)清洗干凈后才能進(jin)(jin)(jin)行(xing)(xing)(xing)。檢驗(yan)的(de)(de)主(zhu)要(yao)內(nei)容(rong)(rong)除(chu)包括外部(bu)檢查(cha)的(de)(de)全(quan)部(bu)內(nei)容(rong)(rong)外，不(bu)銹鋼儲氣(qi)罐，還要(yao)檢驗(yan)內(nei)外表面(mian)的(de)(de)腐(fu)蝕磨損現(xian)象(xiang)；

 分離容(rong)器(qi)(qi):用于完成介質(zhi)的質(zhi)量交換、氣(qi)體凈化、固、液(ye)、氣(qi)分離的容(rong)器(qi)(qi)。貯(zhu)運容(rong)器(qi)(qi):用于盛裝(zhuang)液(ye)體或氣(qi)體物料、貯(zhu)運介質(zhi)或對(dui)壓力起(qi)平衡緩沖作用的容(rong)器(qi)(qi)。20世紀60年(nian)始，蕪湖儲氣(qi)罐，站的發展(zhan)對(dui)反(fan)應堆壓力容(rong)器(qi)(qi)提(ti)出了更高的安全和(he)技術要(yao)求(qiu)，從而促進了壓力容(rong)器(qi)(qi)的進一步發展(zhan)，廣泛應用于各工業部(bu)(bu)門(men)。壓力容(rong)器(qi)(qi)內(nei)(nei)外(wai)部(bu)(bu)檢(jian)驗這種檢(jian)驗必須在停(ting)車和(he)容(rong)器(qi)(qi)內(nei)(nei)部(bu)(bu)清洗干凈后才(cai)能進行。檢(jian)驗的主要(yao)內(nei)(nei)容(rong)除包(bao)括外(wai)部(bu)(bu)檢(jian)查的全部(bu)(bu)內(nei)(nei)容(rong)外(wai)，還要(yao)檢(jian)驗內(nei)(nei)外(wai)表面的腐蝕(shi)磨(mo)損現象；

制作壓力(li)容器時，劃線是壓力(li)容器制造(zao)過程的(de)道(dao)工(gong)序，它直接(jie)(jie)決定(ding)了零(ling)件(jian)成形后的(de)尺寸精度(du)和幾何形狀精度(du)，對以后的(de)組對和焊接(jie)(jie)工(gong)序有(you)著很(hen)大(da)的(de)影響(xiang)。

劃線(xian)(xian)(xian)(xian)是(shi)在原(yuan)材料(liao)或(huo)經初加(jia)工的坯(pi)料(liao)上劃出下料(liao)線(xian)(xian)(xian)(xian)、加(jia)工線(xian)(xian)(xian)(xian)、各種(zhong)(zhong)位置線(xian)(xian)(xian)(xian)和(he)檢(jian)查線(xian)(xian)(xian)(xian)等(deng)，并(bing)打上（或(huo)寫上）必(bi)要(yao)的標志(zhi)、符號。劃線(xian)(xian)(xian)(xian)工序通常包(bao)括對零件的展開、放樣和(he)打標記等(deng)環節。劃線(xian)(xian)(xian)(xian)前應先確定坯(pi)料(liao)尺寸(cun)(cun)。坯(pi)料(liao)尺寸(cun)(cun)由零件展開尺寸(cun)(cun)和(he)各種(zhong)(zhong)加(jia)工余量組成。
