大連膠管在使用前，必須先把膠管內壁滑石粉吹除干凈，防(fang)(fang)止焊割炬的(de)(de)通(tong)道(dao)(dao)被堵塞(sai)。在使用(yong)(yong)(yong)中應避免(mian)受(shou)外(wai)界擠壓和(he)(he)(he)機械損傷(shang)，也(ye)不(bu)得與上(shang)述影響膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)質量的(de)(de)物質接觸，不(bu)得將管(guan)(guan)(guan)身折疊。煤(mei)(mei)炭工業(ye)用(yong)(yong)(yong)油(you)管(guan)(guan)(guan)主要有液壓支(zhi)架(jia)(jia)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)管(guan)(guan)(guan)。近年來，有些煤(mei)(mei)礦(kuang)液壓支(zhi)架(jia)(jia)的(de)(de)壓力(li)要求已(yi)(yi)經提高(gao)，一部(bu)分鋼絲(si)編(bian)織(zhi)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)不(bu)能滿足其性能要求，要求改用(yong)(yong)(yong)鋼絲(si)纏繞油(you)管(guan)(guan)(guan)。此外(wai)，為防(fang)(fang)止煤(mei)(mei)礦(kuang)井下采(cai)煤(mei)(mei)過程中煤(mei)(mei)塵污染和(he)(he)(he)提高(gao)生(sheng)產(chan)安全性，增加了煤(mei)(mei)礦(kuang)用(yong)(yong)(yong)油(you)管(guan)(guan)(guan)的(de)(de)品(pin)(pin)種，如煤(mei)(mei)層探水封孔器伸縮油(you)管(guan)(guan)(guan)，用(yong)(yong)(yong)于(yu)煤(mei)(mei)礦(kuang)井下工作面綜采(cai)前對煤(mei)(mei)層進行注水、注漿等(deng)作業(ye)。據報道(dao)(dao)，國內已(yi)(yi)有廠家生(sheng)產(chan)，并經十幾家煤(mei)(mei)礦(kuang)試用(yong)(yong)(yong)，可替代同類進口(kou)產(chan)品(pin)(pin)。膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶(dai)的(de)(de)發(fa)展，膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)發(fa)展的(de)(de)重點(dian)是提升汽(qi)車用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)制造技(ji)術和(he)(he)(he)產(chan)品(pin)(pin)性能，填補國內高(gao)檔(dang)汽(qi)車用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶(dai)的(de)(de)空白。加快高(gao)壓鋼絲(si)編(bian)織(zhi)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶(dai)和(he)(he)(he)纏繞膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)的(de)(de)更新換代速度，提高(gao)脈(mo)沖壽(shou)命。
