大連膠管在使用前，必須先把膠管內壁(bi)滑石(shi)粉(fen)吹除干凈，防止焊割炬(ju)的通道被堵(du)塞。在使用(yong)(yong)(yong)中應避(bi)免受(shou)外界擠壓(ya)(ya)和機械損傷，也不得與(yu)上述(shu)影響膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)質(zhi)量的物質(zhi)接觸，不得將管(guan)(guan)身折疊。煤(mei)(mei)(mei)炭工業(ye)用(yong)(yong)(yong)油管(guan)(guan)主要有(you)液(ye)壓(ya)(ya)支(zhi)架膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)管(guan)(guan)。近年(nian)來，有(you)些煤(mei)(mei)(mei)礦(kuang)液(ye)壓(ya)(ya)支(zhi)架的壓(ya)(ya)力(li)要求已經提(ti)高，一部分(fen)鋼(gang)(gang)(gang)絲編(bian)(bian)織膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)不能滿足其(qi)性能要求，要求改用(yong)(yong)(yong)鋼(gang)(gang)(gang)絲纏繞油管(guan)(guan)。此外，為防止煤(mei)(mei)(mei)礦(kuang)井(jing)下采(cai)煤(mei)(mei)(mei)過(guo)程中煤(mei)(mei)(mei)塵污染(ran)和提(ti)高生產安全性，增加了(le)煤(mei)(mei)(mei)礦(kuang)用(yong)(yong)(yong)油管(guan)(guan)的品種，如煤(mei)(mei)(mei)層(ceng)(ceng)探(tan)水封(feng)孔(kong)器伸縮油管(guan)(guan)，用(yong)(yong)(yong)于煤(mei)(mei)(mei)礦(kuang)井(jing)下工作面(mian)綜采(cai)前對煤(mei)(mei)(mei)層(ceng)(ceng)進(jin)行注水、注漿等作業(ye)。據報道，國(guo)內已有(you)廠家生產，并經十幾(ji)家煤(mei)(mei)(mei)礦(kuang)試用(yong)(yong)(yong)，可替代同類進(jin)口產品。膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)(jiao)帶(dai)(dai)的發展，膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)發展的重點是提(ti)升汽車(che)(che)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)制造技(ji)術和產品性能，填(tian)補國(guo)內高檔汽車(che)(che)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)(jiao)帶(dai)(dai)的空白。加快高壓(ya)(ya)鋼(gang)(gang)(gang)絲編(bian)(bian)織膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)(jiao)帶(dai)(dai)和纏繞膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)的更新換代速度，提(ti)高脈沖壽命。
