大連膠管在使用前，必須先把膠管內壁滑(hua)石粉吹(chui)除(chu)干(gan)凈，防止(zhi)(zhi)焊割炬的通道被(bei)堵塞(sai)。在(zai)使用(yong)中(zhong)應避免受外界擠壓和(he)機(ji)械損傷，也(ye)不得與上述影響膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)質量的物(wu)質接(jie)觸，不得將管(guan)(guan)身折疊。煤(mei)炭工(gong)業用(yong)油(you)管(guan)(guan)主要有(you)(you)液壓支(zhi)架膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)管(guan)(guan)。近(jin)年來，有(you)(you)些煤(mei)礦液壓支(zhi)架的壓力(li)要求(qiu)(qiu)已(yi)經(jing)提高，一(yi)部分鋼(gang)絲編織膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)不能滿足其性(xing)(xing)能要求(qiu)(qiu)，要求(qiu)(qiu)改用(yong)鋼(gang)絲纏繞油(you)管(guan)(guan)。此外，為防止(zhi)(zhi)煤(mei)礦井下采煤(mei)過(guo)程中(zhong)煤(mei)塵污染和(he)提高生(sheng)產(chan)安全性(xing)(xing)，增加(jia)了煤(mei)礦用(yong)油(you)管(guan)(guan)的品(pin)種，如煤(mei)層探水封孔器伸縮(suo)油(you)管(guan)(guan)，用(yong)于煤(mei)礦井下工(gong)作(zuo)面綜采前對煤(mei)層進(jin)行注水、注漿(jiang)等作(zuo)業。據報道，國(guo)(guo)內已(yi)有(you)(you)廠家生(sheng)產(chan)，并經(jing)十幾家煤(mei)礦試用(yong)，可替代(dai)同類進(jin)口產(chan)品(pin)。膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶(dai)的發展，膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)發展的重點(dian)是提升汽(qi)車用(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)制造技術(shu)和(he)產(chan)品(pin)性(xing)(xing)能，填(tian)補國(guo)(guo)內高檔汽(qi)車用(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶(dai)的空白。加(jia)快高壓鋼(gang)絲編織膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶(dai)和(he)纏繞膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)的更新(xin)換代(dai)速度，提高脈(mo)沖壽命。
