大連膠管在使用前，必須先把膠管內(nei)(nei)(nei)壁(bi)滑石粉吹除干凈，防止焊(han)割(ge)炬(ju)的(de)(de)通道(dao)被堵塞(sai)。在使用(yong)(yong)(yong)中(zhong)(zhong)應避免受外界擠(ji)壓(ya)(ya)和機械(xie)損傷，也不(bu)得與上述影(ying)響膠(jiao)(jiao)管(guan)(guan)(guan)質量(liang)的(de)(de)物質接(jie)觸(chu)，不(bu)得將管(guan)(guan)(guan)身折(zhe)疊。煤(mei)(mei)炭工業用(yong)(yong)(yong)油管(guan)(guan)(guan)主要(yao)有液壓(ya)(ya)支架膠(jiao)(jiao)管(guan)(guan)(guan)管(guan)(guan)(guan)。近年來，有些煤(mei)(mei)礦(kuang)(kuang)液壓(ya)(ya)支架的(de)(de)壓(ya)(ya)力要(yao)求已經提高(gao)，一(yi)部分鋼(gang)絲編(bian)織(zhi)膠(jiao)(jiao)管(guan)(guan)(guan)不(bu)能(neng)滿足其性(xing)(xing)能(neng)要(yao)求，要(yao)求改用(yong)(yong)(yong)鋼(gang)絲纏繞(rao)油管(guan)(guan)(guan)。此外，為防止煤(mei)(mei)礦(kuang)(kuang)井下采煤(mei)(mei)過程中(zhong)(zhong)煤(mei)(mei)塵污染和提高(gao)生產安全性(xing)(xing)，增加了煤(mei)(mei)礦(kuang)(kuang)用(yong)(yong)(yong)油管(guan)(guan)(guan)的(de)(de)品(pin)種，如煤(mei)(mei)層(ceng)探水封孔(kong)器伸縮油管(guan)(guan)(guan)，用(yong)(yong)(yong)于煤(mei)(mei)礦(kuang)(kuang)井下工作(zuo)面綜采前對煤(mei)(mei)層(ceng)進(jin)行(xing)注水、注漿等作(zuo)業。據報道(dao)，國(guo)內(nei)(nei)(nei)已有廠(chang)家(jia)生產，并經十幾家(jia)煤(mei)(mei)礦(kuang)(kuang)試用(yong)(yong)(yong)，可(ke)替代同類進(jin)口(kou)產品(pin)。膠(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)帶的(de)(de)發展，膠(jiao)(jiao)管(guan)(guan)(guan)發展的(de)(de)重點(dian)是提升汽車用(yong)(yong)(yong)膠(jiao)(jiao)管(guan)(guan)(guan)制造技術和產品(pin)性(xing)(xing)能(neng)，填補國(guo)內(nei)(nei)(nei)高(gao)檔汽車用(yong)(yong)(yong)膠(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)帶的(de)(de)空白。加快高(gao)壓(ya)(ya)鋼(gang)絲編(bian)織(zhi)膠(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)帶和纏繞(rao)膠(jiao)(jiao)管(guan)(guan)(guan)的(de)(de)更(geng)新換代速度，提高(gao)脈沖(chong)壽命。
