大連膠管在使用前，必須先把膠管內壁滑石粉吹除干凈，防止焊割炬的(de)(de)(de)(de)通道被(bei)堵塞。在(zai)使(shi)用(yong)(yong)(yong)(yong)中(zhong)應避免受外界(jie)擠壓(ya)(ya)和機械損傷，也不(bu)(bu)得(de)與上(shang)述影響(xiang)膠(jiao)管(guan)質量的(de)(de)(de)(de)物質接(jie)觸，不(bu)(bu)得(de)將管(guan)身折疊。煤(mei)(mei)(mei)炭工業用(yong)(yong)(yong)(yong)油(you)(you)管(guan)主要有(you)(you)液壓(ya)(ya)支(zhi)(zhi)架(jia)膠(jiao)管(guan)管(guan)。近年來(lai)，有(you)(you)些煤(mei)(mei)(mei)礦液壓(ya)(ya)支(zhi)(zhi)架(jia)的(de)(de)(de)(de)壓(ya)(ya)力要求(qiu)已經提高，一(yi)部分鋼絲編織膠(jiao)管(guan)不(bu)(bu)能(neng)(neng)滿足其性能(neng)(neng)要求(qiu)，要求(qiu)改用(yong)(yong)(yong)(yong)鋼絲纏(chan)(chan)繞(rao)油(you)(you)管(guan)。此外，為防止煤(mei)(mei)(mei)礦井下采(cai)煤(mei)(mei)(mei)過程中(zhong)煤(mei)(mei)(mei)塵污染和提高生產安全性，增加了煤(mei)(mei)(mei)礦用(yong)(yong)(yong)(yong)油(you)(you)管(guan)的(de)(de)(de)(de)品(pin)種，如煤(mei)(mei)(mei)層探水封孔(kong)器伸縮油(you)(you)管(guan)，用(yong)(yong)(yong)(yong)于(yu)煤(mei)(mei)(mei)礦井下工作(zuo)面綜采(cai)前(qian)對煤(mei)(mei)(mei)層進(jin)行注(zhu)水、注(zhu)漿等作(zuo)業。據報(bao)道，國(guo)內已有(you)(you)廠家生產，并經十幾家煤(mei)(mei)(mei)礦試(shi)用(yong)(yong)(yong)(yong)，可(ke)替代(dai)同類(lei)進(jin)口產品(pin)。膠(jiao)管(guan)膠(jiao)帶的(de)(de)(de)(de)發展，膠(jiao)管(guan)發展的(de)(de)(de)(de)重點是提升汽車(che)用(yong)(yong)(yong)(yong)膠(jiao)管(guan)制造技術和產品(pin)性能(neng)(neng)，填補國(guo)內高檔汽車(che)用(yong)(yong)(yong)(yong)膠(jiao)管(guan)膠(jiao)帶的(de)(de)(de)(de)空白。加快高壓(ya)(ya)鋼絲編織膠(jiao)管(guan)膠(jiao)帶和纏(chan)(chan)繞(rao)膠(jiao)管(guan)的(de)(de)(de)(de)更(geng)新(xin)換(huan)代(dai)速(su)度，提高脈沖壽命。
