大連膠管在使用前，必須先把膠管內壁(bi)滑石(shi)粉吹除干凈(jing)，防止焊割(ge)炬(ju)的(de)(de)(de)通(tong)道被堵塞(sai)。在使用(yong)中(zhong)應避免受外界擠壓(ya)和機械損傷，也(ye)不得(de)與上述影響(xiang)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)質量(liang)的(de)(de)(de)物質接(jie)觸(chu)，不得(de)將管(guan)(guan)(guan)身折疊。煤(mei)炭工(gong)(gong)業用(yong)油(you)管(guan)(guan)(guan)主(zhu)要有液壓(ya)支架(jia)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)管(guan)(guan)(guan)。近年來，有些煤(mei)礦液壓(ya)支架(jia)的(de)(de)(de)壓(ya)力要求已經提(ti)(ti)高，一部分鋼(gang)絲編織(zhi)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)不能(neng)滿足其性能(neng)要求，要求改用(yong)鋼(gang)絲纏繞油(you)管(guan)(guan)(guan)。此(ci)外，為防止煤(mei)礦井(jing)下采(cai)煤(mei)過程中(zhong)煤(mei)塵污(wu)染(ran)和提(ti)(ti)高生產(chan)(chan)安全(quan)性，增(zeng)加了煤(mei)礦用(yong)油(you)管(guan)(guan)(guan)的(de)(de)(de)品種，如(ru)煤(mei)層探(tan)水(shui)(shui)封孔器伸(shen)縮油(you)管(guan)(guan)(guan)，用(yong)于煤(mei)礦井(jing)下工(gong)(gong)作面綜采(cai)前對煤(mei)層進行(xing)注水(shui)(shui)、注漿等作業。據報道，國內已有廠家(jia)生產(chan)(chan)，并經十幾家(jia)煤(mei)礦試用(yong)，可替代同類進口產(chan)(chan)品。膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶(dai)(dai)的(de)(de)(de)發展(zhan)，膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)發展(zhan)的(de)(de)(de)重(zhong)點是提(ti)(ti)升汽(qi)車用(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)制(zhi)造技術(shu)和產(chan)(chan)品性能(neng)，填補(bu)國內高檔(dang)汽(qi)車用(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶(dai)(dai)的(de)(de)(de)空白(bai)。加快高壓(ya)鋼(gang)絲編織(zhi)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶(dai)(dai)和纏繞膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)的(de)(de)(de)更新換代速(su)度，提(ti)(ti)高脈(mo)沖(chong)壽命。
