大連膠管在使用前，必須先把膠管內壁滑石(shi)粉吹除干凈，防止(zhi)焊割炬的(de)(de)(de)通道(dao)被(bei)堵塞(sai)。在使用(yong)(yong)(yong)(yong)中應(ying)避免受外(wai)界擠壓(ya)和(he)機械(xie)損傷，也(ye)不得(de)與(yu)上述影響(xiang)膠(jiao)(jiao)管(guan)(guan)質(zhi)量(liang)的(de)(de)(de)物(wu)質(zhi)接觸，不得(de)將(jiang)管(guan)(guan)身折疊。煤炭工業(ye)用(yong)(yong)(yong)(yong)油管(guan)(guan)主要有(you)液壓(ya)支(zhi)架(jia)膠(jiao)(jiao)管(guan)(guan)管(guan)(guan)。近年來，有(you)些(xie)煤礦(kuang)(kuang)液壓(ya)支(zhi)架(jia)的(de)(de)(de)壓(ya)力要求(qiu)(qiu)已經提高，一(yi)部(bu)分(fen)鋼(gang)絲(si)編(bian)織膠(jiao)(jiao)管(guan)(guan)不能(neng)滿(man)足其性能(neng)要求(qiu)(qiu)，要求(qiu)(qiu)改(gai)用(yong)(yong)(yong)(yong)鋼(gang)絲(si)纏繞油管(guan)(guan)。此外(wai)，為防止(zhi)煤礦(kuang)(kuang)井下(xia)(xia)采煤過程中煤塵污染和(he)提高生(sheng)(sheng)產(chan)安全性，增加了煤礦(kuang)(kuang)用(yong)(yong)(yong)(yong)油管(guan)(guan)的(de)(de)(de)品種，如煤層探(tan)水封孔器伸縮油管(guan)(guan)，用(yong)(yong)(yong)(yong)于煤礦(kuang)(kuang)井下(xia)(xia)工作面綜采前對煤層進行注水、注漿等作業(ye)。據報道(dao)，國內已有(you)廠(chang)家(jia)生(sheng)(sheng)產(chan)，并經十幾家(jia)煤礦(kuang)(kuang)試用(yong)(yong)(yong)(yong)，可替代(dai)同類進口產(chan)品。膠(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)帶的(de)(de)(de)發(fa)展，膠(jiao)(jiao)管(guan)(guan)發(fa)展的(de)(de)(de)重點(dian)是提升汽車用(yong)(yong)(yong)(yong)膠(jiao)(jiao)管(guan)(guan)制造(zao)技(ji)術和(he)產(chan)品性能(neng)，填(tian)補國內高檔(dang)汽車用(yong)(yong)(yong)(yong)膠(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)帶的(de)(de)(de)空白。加快高壓(ya)鋼(gang)絲(si)編(bian)織膠(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)帶和(he)纏繞膠(jiao)(jiao)管(guan)(guan)的(de)(de)(de)更新換代(dai)速度(du)，提高脈沖壽(shou)命。
