大連膠管在使用前，必須先把膠管內壁滑石粉吹除(chu)干凈，防(fang)止焊(han)割炬的(de)通道被堵塞。在使用(yong)中(zhong)應避免受外(wai)界(jie)擠壓(ya)(ya)和機械損傷(shang)，也不(bu)得與上述(shu)影響膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)質量的(de)物質接觸，不(bu)得將(jiang)管(guan)(guan)(guan)(guan)身折疊。煤炭(tan)工業(ye)用(yong)油(you)(you)管(guan)(guan)(guan)(guan)主要(yao)有(you)液壓(ya)(ya)支架膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)。近年來，有(you)些煤礦液壓(ya)(ya)支架的(de)壓(ya)(ya)力要(yao)求(qiu)已經提(ti)高，一(yi)部分鋼(gang)絲編織膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)不(bu)能(neng)(neng)滿足其性能(neng)(neng)要(yao)求(qiu)，要(yao)求(qiu)改用(yong)鋼(gang)絲纏繞油(you)(you)管(guan)(guan)(guan)(guan)。此外(wai)，為防(fang)止煤礦井下(xia)(xia)采煤過程(cheng)中(zhong)煤塵污染和提(ti)高生(sheng)產安全性，增加(jia)了煤礦用(yong)油(you)(you)管(guan)(guan)(guan)(guan)的(de)品(pin)(pin)種，如煤層(ceng)探水(shui)封孔器(qi)伸縮(suo)油(you)(you)管(guan)(guan)(guan)(guan)，用(yong)于煤礦井下(xia)(xia)工作面綜采前對煤層(ceng)進(jin)(jin)行注水(shui)、注漿等作業(ye)。據報道，國內已有(you)廠家(jia)生(sheng)產，并經十幾家(jia)煤礦試用(yong)，可替代同類進(jin)(jin)口產品(pin)(pin)。膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶的(de)發展(zhan)，膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)發展(zhan)的(de)重點是提(ti)升汽車用(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)制(zhi)造(zao)技(ji)術和產品(pin)(pin)性能(neng)(neng)，填補國內高檔汽車用(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶的(de)空白(bai)。加(jia)快高壓(ya)(ya)鋼(gang)絲編織膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶和纏繞膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)的(de)更新換代速(su)度，提(ti)高脈沖壽命(ming)。
