大連膠管在使用前，必須先把膠管內壁滑石粉(fen)吹(chui)除干凈，防止(zhi)(zhi)焊割炬(ju)的(de)通道被(bei)堵塞(sai)。在使用(yong)(yong)(yong)中應避免受外(wai)界(jie)擠壓(ya)和(he)機械(xie)損傷，也不(bu)得與上述影(ying)響膠(jiao)(jiao)(jiao)管(guan)(guan)質量的(de)物質接觸，不(bu)得將管(guan)(guan)身折疊。煤炭工業用(yong)(yong)(yong)油管(guan)(guan)主要(yao)有(you)(you)(you)液壓(ya)支架膠(jiao)(jiao)(jiao)管(guan)(guan)管(guan)(guan)。近年(nian)來，有(you)(you)(you)些煤礦(kuang)(kuang)(kuang)液壓(ya)支架的(de)壓(ya)力要(yao)求已經(jing)提高，一部(bu)分鋼絲(si)編織膠(jiao)(jiao)(jiao)管(guan)(guan)不(bu)能滿足其性能要(yao)求，要(yao)求改用(yong)(yong)(yong)鋼絲(si)纏繞油管(guan)(guan)。此外(wai)，為防止(zhi)(zhi)煤礦(kuang)(kuang)(kuang)井(jing)下采煤過程中煤塵污(wu)染和(he)提高生(sheng)產安全性，增加(jia)了煤礦(kuang)(kuang)(kuang)用(yong)(yong)(yong)油管(guan)(guan)的(de)品(pin)種，如煤層(ceng)探水封孔器伸(shen)縮油管(guan)(guan)，用(yong)(yong)(yong)于煤礦(kuang)(kuang)(kuang)井(jing)下工作面綜采前對煤層(ceng)進(jin)行注水、注漿等作業。據(ju)報道，國(guo)內已有(you)(you)(you)廠家生(sheng)產，并經(jing)十幾家煤礦(kuang)(kuang)(kuang)試用(yong)(yong)(yong)，可替代(dai)同類進(jin)口產品(pin)。膠(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)帶的(de)發(fa)展，膠(jiao)(jiao)(jiao)管(guan)(guan)發(fa)展的(de)重(zhong)點是提升(sheng)汽車用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)制造技術和(he)產品(pin)性能，填(tian)補國(guo)內高檔汽車用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)帶的(de)空白。加(jia)快高壓(ya)鋼絲(si)編織膠(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)帶和(he)纏繞膠(jiao)(jiao)(jiao)管(guan)(guan)的(de)更(geng)新換代(dai)速度，提高脈沖壽命。
