大連膠管在使用前，必須先把膠管內(nei)壁(bi)滑石粉吹除(chu)干凈，防(fang)止(zhi)焊割炬(ju)的(de)(de)通(tong)道(dao)被堵(du)塞(sai)。在使(shi)用(yong)(yong)(yong)中應避免(mian)受外界擠壓(ya)和機(ji)械損傷，也不(bu)得(de)與上述影響膠(jiao)(jiao)(jiao)管(guan)(guan)質(zhi)量的(de)(de)物(wu)質(zhi)接觸(chu)，不(bu)得(de)將管(guan)(guan)身折疊。煤(mei)炭工業(ye)用(yong)(yong)(yong)油管(guan)(guan)主要(yao)有液壓(ya)支架膠(jiao)(jiao)(jiao)管(guan)(guan)管(guan)(guan)。近年來，有些煤(mei)礦(kuang)液壓(ya)支架的(de)(de)壓(ya)力要(yao)求已經提(ti)(ti)(ti)高(gao)，一部分鋼絲編織(zhi)(zhi)膠(jiao)(jiao)(jiao)管(guan)(guan)不(bu)能滿足其(qi)性(xing)能要(yao)求，要(yao)求改用(yong)(yong)(yong)鋼絲纏繞油管(guan)(guan)。此外，為(wei)防(fang)止(zhi)煤(mei)礦(kuang)井(jing)下采(cai)煤(mei)過程中煤(mei)塵(chen)污染和提(ti)(ti)(ti)高(gao)生產安全性(xing)，增加了煤(mei)礦(kuang)用(yong)(yong)(yong)油管(guan)(guan)的(de)(de)品(pin)種，如煤(mei)層(ceng)探水(shui)封孔器伸縮油管(guan)(guan)，用(yong)(yong)(yong)于煤(mei)礦(kuang)井(jing)下工作(zuo)面綜采(cai)前對煤(mei)層(ceng)進(jin)行注水(shui)、注漿等(deng)作(zuo)業(ye)。據(ju)報(bao)道(dao)，國內(nei)已有廠家生產，并經十幾家煤(mei)礦(kuang)試用(yong)(yong)(yong)，可替代同類進(jin)口產品(pin)。膠(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)帶的(de)(de)發展(zhan)，膠(jiao)(jiao)(jiao)管(guan)(guan)發展(zhan)的(de)(de)重點是提(ti)(ti)(ti)升(sheng)汽(qi)車(che)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)制造(zao)技術和產品(pin)性(xing)能，填補(bu)國內(nei)高(gao)檔汽(qi)車(che)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)帶的(de)(de)空白。加快(kuai)高(gao)壓(ya)鋼絲編織(zhi)(zhi)膠(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)帶和纏繞膠(jiao)(jiao)(jiao)管(guan)(guan)的(de)(de)更新換代速度，提(ti)(ti)(ti)高(gao)脈沖壽命。
