大連膠管在使用前，必須先把膠管內(nei)壁滑(hua)石粉吹除干凈，防止(zhi)焊割(ge)炬的(de)(de)(de)(de)通道被堵塞。在使用(yong)中(zhong)應避(bi)免受外界擠壓(ya)(ya)和(he)(he)(he)機械損傷，也不得與(yu)上述影響膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)質量的(de)(de)(de)(de)物質接觸，不得將管(guan)(guan)(guan)(guan)身折(zhe)疊。煤(mei)炭工業用(yong)油(you)管(guan)(guan)(guan)(guan)主要有液壓(ya)(ya)支架膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)。近年來，有些煤(mei)礦液壓(ya)(ya)支架的(de)(de)(de)(de)壓(ya)(ya)力(li)要求(qiu)已經提(ti)高，一(yi)部分鋼絲編(bian)織膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)不能滿足其性(xing)能要求(qiu)，要求(qiu)改用(yong)鋼絲纏繞油(you)管(guan)(guan)(guan)(guan)。此外，為防止(zhi)煤(mei)礦井下采煤(mei)過程中(zhong)煤(mei)塵(chen)污染和(he)(he)(he)提(ti)高生產(chan)安全性(xing)，增加了(le)煤(mei)礦用(yong)油(you)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)品種，如(ru)煤(mei)層探水(shui)封孔器伸縮油(you)管(guan)(guan)(guan)(guan)，用(yong)于(yu)煤(mei)礦井下工作面(mian)綜采前對煤(mei)層進行注水(shui)、注漿等作業。據報道，國內(nei)已有廠家生產(chan)，并經十幾(ji)家煤(mei)礦試用(yong)，可替代同類進口產(chan)品。膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)(jiao)帶(dai)的(de)(de)(de)(de)發展，膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)發展的(de)(de)(de)(de)重點是提(ti)升汽(qi)車用(yong)膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)制造(zao)技術和(he)(he)(he)產(chan)品性(xing)能，填補國內(nei)高檔(dang)汽(qi)車用(yong)膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)(jiao)帶(dai)的(de)(de)(de)(de)空白。加快高壓(ya)(ya)鋼絲編(bian)織膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)(jiao)帶(dai)和(he)(he)(he)纏繞膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)更(geng)新換代速度，提(ti)高脈沖(chong)壽命。
