大連膠管在使用前，必須先把膠管內(nei)(nei)壁(bi)滑石粉吹除干凈，防止(zhi)焊割炬(ju)的(de)通(tong)道(dao)被(bei)堵塞(sai)。在使用(yong)(yong)(yong)中應避免受外界擠(ji)壓(ya)(ya)和機械損傷(shang)，也不(bu)(bu)得(de)與上述影響膠(jiao)(jiao)(jiao)管(guan)(guan)質(zhi)量(liang)的(de)物質(zhi)接觸，不(bu)(bu)得(de)將管(guan)(guan)身折疊。煤(mei)(mei)炭工業(ye)用(yong)(yong)(yong)油(you)管(guan)(guan)主要有液壓(ya)(ya)支架膠(jiao)(jiao)(jiao)管(guan)(guan)管(guan)(guan)。近年來，有些煤(mei)(mei)礦液壓(ya)(ya)支架的(de)壓(ya)(ya)力要求已經(jing)提(ti)高(gao)，一部分鋼絲編(bian)織(zhi)膠(jiao)(jiao)(jiao)管(guan)(guan)不(bu)(bu)能滿足(zu)其性(xing)能要求，要求改(gai)用(yong)(yong)(yong)鋼絲纏(chan)繞油(you)管(guan)(guan)。此外，為防止(zhi)煤(mei)(mei)礦井下(xia)采煤(mei)(mei)過程中煤(mei)(mei)塵污(wu)染和提(ti)高(gao)生產(chan)(chan)安全性(xing)，增(zeng)加了煤(mei)(mei)礦用(yong)(yong)(yong)油(you)管(guan)(guan)的(de)品種，如(ru)煤(mei)(mei)層探水封(feng)孔器伸(shen)縮(suo)油(you)管(guan)(guan)，用(yong)(yong)(yong)于(yu)煤(mei)(mei)礦井下(xia)工作(zuo)面綜采前(qian)對(dui)煤(mei)(mei)層進行注水、注漿等作(zuo)業(ye)。據報道(dao)，國內(nei)(nei)已有廠家生產(chan)(chan)，并經(jing)十幾家煤(mei)(mei)礦試用(yong)(yong)(yong)，可替代同類進口(kou)產(chan)(chan)品。膠(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)帶(dai)的(de)發展，膠(jiao)(jiao)(jiao)管(guan)(guan)發展的(de)重點是提(ti)升汽(qi)車(che)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)制(zhi)造技術和產(chan)(chan)品性(xing)能，填(tian)補國內(nei)(nei)高(gao)檔(dang)汽(qi)車(che)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)帶(dai)的(de)空白(bai)。加快高(gao)壓(ya)(ya)鋼絲編(bian)織(zhi)膠(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)帶(dai)和纏(chan)繞膠(jiao)(jiao)(jiao)管(guan)(guan)的(de)更新換代速(su)度，提(ti)高(gao)脈沖壽命。
