大連膠管在使用前，必須先把膠管內(nei)(nei)壁滑石粉吹除干凈(jing)，防止焊(han)割(ge)炬的(de)(de)(de)(de)通(tong)道被堵(du)塞。在使(shi)用(yong)(yong)(yong)(yong)中應避免(mian)受外(wai)界擠壓(ya)和機械損傷(shang)，也不得與上述(shu)影響(xiang)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)質(zhi)量的(de)(de)(de)(de)物質(zhi)接觸，不得將管(guan)(guan)(guan)身折疊。煤(mei)(mei)炭工業(ye)用(yong)(yong)(yong)(yong)油(you)管(guan)(guan)(guan)主要(yao)有液(ye)壓(ya)支架膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)管(guan)(guan)(guan)。近年(nian)來，有些(xie)煤(mei)(mei)礦(kuang)(kuang)液(ye)壓(ya)支架的(de)(de)(de)(de)壓(ya)力要(yao)求已(yi)經(jing)提高，一部分鋼絲編織膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)不能滿足其性能要(yao)求，要(yao)求改用(yong)(yong)(yong)(yong)鋼絲纏繞油(you)管(guan)(guan)(guan)。此外(wai)，為防止煤(mei)(mei)礦(kuang)(kuang)井(jing)下采(cai)煤(mei)(mei)過程中煤(mei)(mei)塵污染和提高生產(chan)安全性，增加了煤(mei)(mei)礦(kuang)(kuang)用(yong)(yong)(yong)(yong)油(you)管(guan)(guan)(guan)的(de)(de)(de)(de)品(pin)種，如煤(mei)(mei)層探水封孔器伸縮油(you)管(guan)(guan)(guan)，用(yong)(yong)(yong)(yong)于(yu)煤(mei)(mei)礦(kuang)(kuang)井(jing)下工作面綜采(cai)前對煤(mei)(mei)層進行注水、注漿等作業(ye)。據報道，國(guo)內(nei)(nei)已(yi)有廠家(jia)生產(chan)，并經(jing)十幾(ji)家(jia)煤(mei)(mei)礦(kuang)(kuang)試用(yong)(yong)(yong)(yong)，可替代同類進口(kou)產(chan)品(pin)。膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶的(de)(de)(de)(de)發展，膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)發展的(de)(de)(de)(de)重點是提升汽車(che)用(yong)(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)制(zhi)造技術和產(chan)品(pin)性能，填補國(guo)內(nei)(nei)高檔汽車(che)用(yong)(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶的(de)(de)(de)(de)空白。加快高壓(ya)鋼絲編織膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶和纏繞膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)的(de)(de)(de)(de)更新換代速度，提高脈沖壽命。
