隨著應用的不斷廣泛，儲油罐生產廠家也(ye)不斷的增多。儲油罐(guan)(guan)的材(cai)(cai)料(liao)分(fen)為罐(guan)(guan)體材(cai)(cai)料(liao)和附(fu)屬(shu)(shu)設(she)施材(cai)(cai)料(liao)。罐(guan)(guan)體材(cai)(cai)料(liao)可按抗(kang)拉(la)屈(qu)服強(qiang)度(du)（6s）或(huo)抗(kang)拉(la)標準(zhun)強(qiang)度(du)（6b）分(fen)為低強(qiang)鋼(gang)和高強(qiang)鋼(gang)，高強(qiang)鋼(gang)多用(yong)(yong)于5000m3以上儲罐(guan)(guan)；附(fu)屬(shu)(shu)設(she)施（包(bao)括抗(kang)風圈梁、鎖(suo)口、盤梯、護欄等(deng)）均采(cai)用(yong)(yong)強(qiang)度(du)較(jiao)低的普通碳素結構鋼(gang)，其(qi)余配(pei)件、附(fu)件則根據不同的用(yong)(yong)途采(cai)用(yong)(yong)其(qi)他材(cai)(cai)質(zhi)。制造儲罐(guan)(guan)常用(yong)(yong)的國產鋼(gang)材(cai)(cai)有20、20R、16Mn、16MnR以及Q235系列等(deng)。

    構造拱頂(ding)儲罐(guan)(guan)(guan)(guan)是指罐(guan)(guan)(guan)(guan)頂(ding)為(wei)球冠狀、罐(guan)(guan)(guan)(guan)體為(wei)圓柱形(xing)的一(yi)種鋼(gang)(gang)制(zhi)容器。拱頂(ding)儲罐(guan)(guan)(guan)(guan)制(zhi)造簡單、造價(jia)低廉，所以(yi)國(guo)內(nei)外許多行(xing)業應用(yong)最(zui)為(wei)廣泛，最(zui)常用(yong)的容積(ji)為(wei)1000-10000m3，目前(qian)，國(guo)內(nei)拱頂(ding)儲罐(guan)(guan)(guan)(guan)的最(zui)大容積(ji)已經(jing)達(da)到30000m3。 罐(guan)(guan)(guan)(guan)底(di)(di)：罐(guan)(guan)(guan)(guan)底(di)(di)由鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)拼裝而成，罐(guan)(guan)(guan)(guan)底(di)(di)中(zhong)部的鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)為(wei)中(zhong)幅板(ban)(ban)(ban)(ban)(ban)，周邊的鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)為(wei)邊緣(yuan)(yuan)板(ban)(ban)(ban)(ban)(ban)。邊緣(yuan)(yuan)板(ban)(ban)(ban)(ban)(ban)可采用(yong)條形(xing)板(ban)(ban)(ban)(ban)(ban)，也(ye)可采用(yong)弓形(xing)板(ban)(ban)(ban)(ban)(ban)。一(yi)般情況(kuang)下(xia)，儲罐(guan)(guan)(guan)(guan)內(nei)經(jing)＜16.5m時，宜(yi)采用(yong)條形(xing)邊緣(yuan)(yuan)板(ban)(ban)(ban)(ban)(ban)，儲罐(guan)(guan)(guan)(guan)內(nei)經(jing)≥16.5m時，宜(yi)采用(yong)弓形(xing)邊緣(yuan)(yuan)板(ban)(ban)(ban)(ban)(ban)。 罐(guan)(guan)(guan)(guan)壁由多圈(quan)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)組對焊接而成，分(fen)為(wei)套筒式和直(zhi)線式。

    套筒式(shi)罐(guan)(guan)壁板環向焊縫(feng)(feng)采用(yong)(yong)搭接(jie)(jie)，縱(zong)向焊縫(feng)(feng)為對(dui)(dui)接(jie)(jie)。拱頂儲罐(guan)(guan)多(duo)采用(yong)(yong)該(gai)形(xing)式(shi)，其優點是便于(yu)(yu)各(ge)圈壁板組對(dui)(dui)，采用(yong)(yong)倒裝法(fa)施工(gong)比較(jiao)安全。 直線(xian)式(shi)罐(guan)(guan)壁板環向焊縫(feng)(feng)為對(dui)(dui)接(jie)(jie)，優點是罐(guan)(guan)壁整體自上而下(xia)直徑相同，特別適合用(yong)(yong)于(yu)(yu)內浮(fu)頂儲罐(guan)(guan)，但(dan)組對(dui)(dui)安裝要求較(jiao)高、難(nan)度亦較(jiao)大。 罐(guan)(guan)頂：罐(guan)(guan)頂有多(duo)塊扇(shan)形(xing)板組對(dui)(dui)焊接(jie)(jie)而成(cheng)球冠(guan)狀(zhuang)，罐(guan)(guan)頂內測(ce)采用(yong)(yong)扁鋼(gang)制成(cheng)加強(qiang)筋，各(ge)個扇(shan)形(xing)板之間采用(yong)(yong)搭接(jie)(jie)焊縫(feng)(feng)，整個罐(guan)(guan)頂與罐(guan)(guan)壁板上部的(de)角(jiao)鋼(gang)圈（或稱鎖口）焊接(jie)(jie)成(cheng)一體。
