大連膠管在使用前，必須先把膠管內(nei)壁滑石粉吹除(chu)干凈，防止(zhi)焊割(ge)炬的(de)通道被堵塞。在使用(yong)(yong)(yong)中應避免受外界擠(ji)壓和(he)機(ji)械損傷，也不得(de)與上述影響膠(jiao)管(guan)(guan)(guan)質(zhi)量的(de)物質(zhi)接觸(chu)，不得(de)將管(guan)(guan)(guan)身折疊。煤炭工(gong)業(ye)用(yong)(yong)(yong)油管(guan)(guan)(guan)主要(yao)有(you)液(ye)壓支(zhi)架(jia)膠(jiao)管(guan)(guan)(guan)管(guan)(guan)(guan)。近(jin)年來，有(you)些煤礦(kuang)液(ye)壓支(zhi)架(jia)的(de)壓力(li)要(yao)求(qiu)(qiu)已(yi)經(jing)提高(gao)，一部分(fen)鋼絲(si)編織膠(jiao)管(guan)(guan)(guan)不能滿足(zu)其(qi)性能要(yao)求(qiu)(qiu)，要(yao)求(qiu)(qiu)改用(yong)(yong)(yong)鋼絲(si)纏繞油管(guan)(guan)(guan)。此(ci)外，為防止(zhi)煤礦(kuang)井下(xia)采煤過程中煤塵(chen)污染(ran)和(he)提高(gao)生產(chan)(chan)(chan)安全性，增(zeng)加(jia)(jia)了煤礦(kuang)用(yong)(yong)(yong)油管(guan)(guan)(guan)的(de)品種(zhong)，如煤層探(tan)水封孔(kong)器伸縮油管(guan)(guan)(guan)，用(yong)(yong)(yong)于(yu)煤礦(kuang)井下(xia)工(gong)作(zuo)(zuo)面綜采前對煤層進(jin)行注水、注漿等作(zuo)(zuo)業(ye)。據報道，國內(nei)已(yi)有(you)廠家生產(chan)(chan)(chan)，并經(jing)十幾(ji)家煤礦(kuang)試用(yong)(yong)(yong)，可替代同類進(jin)口(kou)產(chan)(chan)(chan)品。膠(jiao)管(guan)(guan)(guan)膠(jiao)帶的(de)發(fa)展，膠(jiao)管(guan)(guan)(guan)發(fa)展的(de)重點是提升汽車用(yong)(yong)(yong)膠(jiao)管(guan)(guan)(guan)制(zhi)造(zao)技術(shu)和(he)產(chan)(chan)(chan)品性能，填(tian)補國內(nei)高(gao)檔(dang)汽車用(yong)(yong)(yong)膠(jiao)管(guan)(guan)(guan)膠(jiao)帶的(de)空白。加(jia)(jia)快高(gao)壓鋼絲(si)編織膠(jiao)管(guan)(guan)(guan)膠(jiao)帶和(he)纏繞膠(jiao)管(guan)(guan)(guan)的(de)更新換代速度(du)，提高(gao)脈沖壽命。
