20世(shi)紀70年代(dai)后期,我國就開始了(le)(le)用(yong)(yong)無縫(feng)鋼管(guan)(guan)制(zhi)造(zao)(zao)(zao)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping),但由(you)于氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)收(shou)底封口技(ji)(ji)術(shu)(shu)沒有過關(guan),致使(shi)這一(yi)工(gong)(gong)藝未能(neng)得到(dao)(dao)進一(yi)步(bu)擴(kuo)(kuo)展(zhan),同時(shi)也(ye)使(shi)管(guan)(guan)制(zhi)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)的(de)(de)(de)發(fa)展(zhan)受到(dao)(dao)了(le)(le)影響。直(zhi)到(dao)(dao)90年代(dai)初(chu),北(bei)京(jing)天(tian)海(hai)公(gong)司成(cheng)(cheng)(cheng)功(gong)地掌握(wo)了(le)(le)用(yong)(yong)無縫(feng)管(guan)(guan)制(zhi)瓶(ping)(ping)(ping)(ping)(ping)(ping)收(shou)底的(de)(de)(de)關(guan)鍵技(ji)(ji)術(shu)(shu),氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)制(zhi)造(zao)(zao)(zao)工(gong)(gong)藝才從主要采(cai)用(yong)(yong)沖拔(ba)(ba)瓶(ping)(ping)(ping)(ping)(ping)(ping)逐(zhu)步(bu)轉向管(guan)(guan)制(zhi)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)發(fa)展(zhan)。管(guan)(guan)制(zhi)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)由(you)于具有內外表面質(zhi)量(liang)(liang)好、尺寸(cun)精度高(gao)、重量(liang)(liang)輕、生(sheng)產(chan)效率(lv)和成(cheng)(cheng)(cheng)材率(lv)高(gao)、成(cheng)(cheng)(cheng)本(ben)低、制(zhi)瓶(ping)(ping)(ping)(ping)(ping)(ping)工(gong)(gong)序簡單等一(yi)系(xi)列優點(dian),深受氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)企(qi)業的(de)(de)(de)歡迎(ying)。管(guan)(guan)制(zhi)瓶(ping)(ping)(ping)(ping)(ping)(ping)制(zhi)造(zao)(zao)(zao)技(ji)(ji)術(shu)(shu)的(de)(de)(de)進步(bu),推動了(le)(le)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)行(xing)業發(fa)展(zhan)。90年代(dai)后,隨(sui)著(zhu)國內連軋(ya)管(guan)(guan)機組的(de)(de)(de)建設,連軋(ya)管(guan)(guan)機的(de)(de)(de)生(sheng)產(chan)工(gong)(gong)藝更適合(he)大徑壁(bi)比(bi)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)管(guan)(guan)的(de)(de)(de)生(sheng)產(chan),使(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)管(guan)(guan)的(de)(de)(de)生(sheng)產(chan)效率(lv)、合(he)格率(lv)、成(cheng)(cheng)(cheng)材率(lv)大幅度提升,氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)管(guan)(guan)的(de)(de)(de)產(chan)量(liang)(liang)呈大幅增長,并拉開了(le)(le)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)管(guan)(guan)快(kuai)速發(fa)展(zhan)的(de)(de)(de)序幕。進入21世(shi)紀以來,隨(sui)著(zhu)國民(min)經濟(ji)快(kuai)速發(fa)展(zhan)的(de)(de)(de)同時(shi),國家對大氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)污(wu)染物排放也(ye)提出了(le)(le)更高(gao)要求,天(tian)然氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)作(zuo)為一(yi)種清潔(jie)高(gao)效能(neng)源在城鎮居民(min)生(sheng)活中(zhong)越來越多(duo)地被(bei)廣(guang)泛應用(yong)(yong)。在這樣的(de)(de)(de)形勢下(xia)采(cai)用(yong)(yong)充裝壓縮天(tian)然氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)纏繞氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)、拖車(che)用(yong)(yong)大口徑氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)應運而生(sheng),并促使(shi)著(zhu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)管(guan)(guan)向輕量(liang)(liang)化、大口徑方向發(fa)展(zhan),采(cai)用(yong)(yong)熱(re)軋(ya)+冷拔(ba)(ba)、熱(re)軋(ya)+擴(kuo)(kuo)管(guan)(guan)或(huo)熱(re)軋(ya)+擴(kuo)(kuo)管(guan)(guan)+冷拔(ba)(ba)等氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)管(guan)(guan)生(sheng)產(chan)工(gong)(gong)藝也(ye)隨(sui)之發(fa)展(zhan)起來,不(bu)斷滿足氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)行(xing)業發(fa)展(zhan)的(de)(de)(de)需求。目前,采(cai)用(yong)(yong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)管(guan)(guan)制(zhi)造(zao)(zao)(zao)的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)、蓄(xu)能(neng)器等高(gao)壓容器已(yi)廣(guang)泛用(yong)(yong)于石(shi)油(you)(天(tian)然氣(qi)(qi)(qi)(qi)(qi)(qi)(qi))、化工(gong)(gong)、機械、冶金、能(neng)源、輕工(gong)(gong)、國防、環保、海(hai)洋(yang)、空間、建筑、消(xiao)防、衛生(sheng)、運輸等各(ge)個領域。我國已(yi)是名副其實的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)和氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)(ping)(ping)(ping)(ping)(ping)管(guan)(guan)的(de)(de)(de)生(sheng)產(chan)大國,并批量(liang)(liang)出口到(dao)(dao)世(shi)界(jie)各(ge)地。
