大連膠管在使用前，必須先把膠管內(nei)壁滑石粉(fen)吹除(chu)干(gan)凈，防(fang)止焊割(ge)炬的通道(dao)被堵塞。在使用(yong)中(zhong)應避免受(shou)外(wai)界擠(ji)壓(ya)(ya)(ya)和機械損傷，也(ye)不得與上述影響膠(jiao)管(guan)(guan)(guan)(guan)質量(liang)的物質接觸，不得將管(guan)(guan)(guan)(guan)身折疊。煤炭(tan)工(gong)(gong)業用(yong)油管(guan)(guan)(guan)(guan)主要有液壓(ya)(ya)(ya)支架(jia)膠(jiao)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)。近(jin)年來，有些煤礦液壓(ya)(ya)(ya)支架(jia)的壓(ya)(ya)(ya)力要求已經提(ti)(ti)高(gao)，一(yi)部(bu)分鋼絲編(bian)織膠(jiao)管(guan)(guan)(guan)(guan)不能滿足其性(xing)能要求，要求改用(yong)鋼絲纏繞(rao)油管(guan)(guan)(guan)(guan)。此外(wai)，為防(fang)止煤礦井下(xia)采(cai)煤過程(cheng)中(zhong)煤塵污(wu)染和提(ti)(ti)高(gao)生(sheng)產(chan)(chan)安(an)全性(xing)，增加(jia)了(le)煤礦用(yong)油管(guan)(guan)(guan)(guan)的品(pin)種(zhong)，如煤層探水封孔器伸縮(suo)油管(guan)(guan)(guan)(guan)，用(yong)于(yu)煤礦井下(xia)工(gong)(gong)作(zuo)面綜采(cai)前對煤層進行注水、注漿等(deng)作(zuo)業。據報道(dao)，國(guo)內(nei)已有廠家生(sheng)產(chan)(chan)，并經十幾家煤礦試用(yong)，可替代同類進口產(chan)(chan)品(pin)。膠(jiao)管(guan)(guan)(guan)(guan)膠(jiao)帶(dai)(dai)的發展，膠(jiao)管(guan)(guan)(guan)(guan)發展的重點是(shi)提(ti)(ti)升(sheng)汽車用(yong)膠(jiao)管(guan)(guan)(guan)(guan)制造技術和產(chan)(chan)品(pin)性(xing)能，填補國(guo)內(nei)高(gao)檔汽車用(yong)膠(jiao)管(guan)(guan)(guan)(guan)膠(jiao)帶(dai)(dai)的空白。加(jia)快高(gao)壓(ya)(ya)(ya)鋼絲編(bian)織膠(jiao)管(guan)(guan)(guan)(guan)膠(jiao)帶(dai)(dai)和纏繞(rao)膠(jiao)管(guan)(guan)(guan)(guan)的更新換代速度，提(ti)(ti)高(gao)脈沖壽命。
