20世(shi)紀(ji)70年(nian)代后(hou)期,我國就(jiu)開(kai)始(shi)了用(yong)無縫(feng)鋼(gang)管(guan)(guan)制(zhi)造氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping),但由于(yu)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)收底(di)(di)封口(kou)技術沒有(you)過關,致使(shi)這(zhe)一(yi)工(gong)(gong)(gong)藝(yi)未(wei)能(neng)得到(dao)進(jin)一(yi)步擴展(zhan)(zhan)(zhan),同(tong)時也(ye)使(shi)管(guan)(guan)制(zhi)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)的(de)(de)發(fa)(fa)展(zhan)(zhan)(zhan)受(shou)到(dao)了影響。直到(dao)90年(nian)代初,北京天(tian)(tian)海(hai)公司成(cheng)(cheng)功地掌握了用(yong)無縫(feng)管(guan)(guan)制(zhi)瓶(ping)(ping)收底(di)(di)的(de)(de)關鍵(jian)技術,氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)制(zhi)造工(gong)(gong)(gong)藝(yi)才(cai)從主要采(cai)(cai)用(yong)沖拔瓶(ping)(ping)逐步轉向管(guan)(guan)制(zhi)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)發(fa)(fa)展(zhan)(zhan)(zhan)。管(guan)(guan)制(zhi)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)由于(yu)具有(you)內(nei)(nei)外表(biao)面質(zhi)量(liang)(liang)好、尺寸精度(du)(du)高(gao)、重(zhong)量(liang)(liang)輕、生(sheng)(sheng)產效(xiao)率(lv)(lv)和成(cheng)(cheng)材率(lv)(lv)高(gao)、成(cheng)(cheng)本低、制(zhi)瓶(ping)(ping)工(gong)(gong)(gong)序簡(jian)單等(deng)一(yi)系列(lie)優點,深受(shou)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)企業的(de)(de)歡迎。管(guan)(guan)制(zhi)瓶(ping)(ping)制(zhi)造技術的(de)(de)進(jin)步,推動了氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)行(xing)業發(fa)(fa)展(zhan)(zhan)(zhan)。90年(nian)代后(hou),隨著(zhu)(zhu)國內(nei)(nei)連(lian)(lian)軋(ya)(ya)管(guan)(guan)機(ji)組的(de)(de)建設,連(lian)(lian)軋(ya)(ya)管(guan)(guan)機(ji)的(de)(de)生(sheng)(sheng)產工(gong)(gong)(gong)藝(yi)更(geng)適(shi)合(he)大徑壁(bi)比氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)管(guan)(guan)的(de)(de)生(sheng)(sheng)產,使(shi)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)管(guan)(guan)的(de)(de)生(sheng)(sheng)產效(xiao)率(lv)(lv)、合(he)格率(lv)(lv)、成(cheng)(cheng)材率(lv)(lv)大幅度(du)(du)提升,氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)管(guan)(guan)的(de)(de)產量(liang)(liang)呈大幅增長(chang),并拉開(kai)了氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)管(guan)(guan)快(kuai)速發(fa)(fa)展(zhan)(zhan)(zhan)的(de)(de)序幕。進(jin)入(ru)21世(shi)紀(ji)以來(lai),隨著(zhu)(zhu)國民(min)經濟快(kuai)速發(fa)(fa)展(zhan)(zhan)(zhan)的(de)(de)同(tong)時,國家對大氣(qi)(qi)(qi)(qi)(qi)污(wu)染物排放(fang)也(ye)提出了更(geng)高(gao)要求,天(tian)(tian)然氣(qi)(qi)(qi)(qi)(qi)作為一(yi)種(zhong)清潔高(gao)效(xiao)能(neng)源在(zai)城(cheng)鎮(zhen)居民(min)生(sheng)(sheng)活(huo)中越來(lai)越多地被廣泛應用(yong)。在(zai)這(zhe)樣的(de)(de)形勢下(xia)采(cai)(cai)用(yong)充裝壓縮(suo)天(tian)(tian)然氣(qi)(qi)(qi)(qi)(qi)的(de)(de)纏繞氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)、拖車用(yong)大口(kou)徑氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)應運而(er)生(sheng)(sheng),并促使(shi)著(zhu)(zhu)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)管(guan)(guan)向輕量(liang)(liang)化(hua)、大口(kou)徑方向發(fa)(fa)展(zhan)(zhan)(zhan),采(cai)(cai)用(yong)熱(re)軋(ya)(ya)+冷拔、熱(re)軋(ya)(ya)+擴管(guan)(guan)或熱(re)軋(ya)(ya)+擴管(guan)(guan)+冷拔等(deng)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)管(guan)(guan)生(sheng)(sheng)產工(gong)(gong)(gong)藝(yi)也(ye)隨之(zhi)發(fa)(fa)展(zhan)(zhan)(zhan)起來(lai),不斷滿(man)足(zu)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)行(xing)業發(fa)(fa)展(zhan)(zhan)(zhan)的(de)(de)需(xu)求。目前,采(cai)(cai)用(yong)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)管(guan)(guan)制(zhi)造的(de)(de)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)、蓄能(neng)器(qi)等(deng)高(gao)壓容器(qi)已廣泛用(yong)于(yu)石油(天(tian)(tian)然氣(qi)(qi)(qi)(qi)(qi))、化(hua)工(gong)(gong)(gong)、機(ji)械(xie)、冶金、能(neng)源、輕工(gong)(gong)(gong)、國防、環保、海(hai)洋、空間、建筑、消防、衛(wei)生(sheng)(sheng)、運輸(shu)等(deng)各個領域(yu)。我國已是(shi)名副其實的(de)(de)氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)和氣(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)管(guan)(guan)的(de)(de)生(sheng)(sheng)產大國,并批量(liang)(liang)出口(kou)到(dao)世(shi)界各地。
