大連膠管在使用前，必須先把膠管內(nei)壁滑石粉(fen)吹(chui)除干(gan)凈，防止(zhi)焊(han)割炬的(de)(de)(de)通道被堵塞。在使用(yong)(yong)(yong)中(zhong)應避免(mian)受外(wai)(wai)界擠壓(ya)(ya)和(he)機械損傷，也不(bu)(bu)得與(yu)上(shang)述(shu)影(ying)響(xiang)膠(jiao)(jiao)管(guan)質量的(de)(de)(de)物質接觸(chu)，不(bu)(bu)得將管(guan)身折疊。煤炭(tan)工業(ye)用(yong)(yong)(yong)油管(guan)主(zhu)要有(you)(you)液(ye)壓(ya)(ya)支架膠(jiao)(jiao)管(guan)管(guan)。近年來，有(you)(you)些(xie)煤礦液(ye)壓(ya)(ya)支架的(de)(de)(de)壓(ya)(ya)力要求(qiu)已(yi)經提(ti)高(gao)(gao)，一(yi)部分鋼(gang)絲編織(zhi)膠(jiao)(jiao)管(guan)不(bu)(bu)能滿(man)足其性能要求(qiu)，要求(qiu)改用(yong)(yong)(yong)鋼(gang)絲纏繞油管(guan)。此外(wai)(wai)，為(wei)防止(zhi)煤礦井下采(cai)煤過(guo)程(cheng)中(zhong)煤塵(chen)污染和(he)提(ti)高(gao)(gao)生(sheng)產安全性，增加了煤礦用(yong)(yong)(yong)油管(guan)的(de)(de)(de)品(pin)種，如煤層(ceng)(ceng)探水封孔器伸(shen)縮油管(guan)，用(yong)(yong)(yong)于煤礦井下工作面綜采(cai)前(qian)對煤層(ceng)(ceng)進(jin)行注水、注漿等(deng)作業(ye)。據報道，國內(nei)已(yi)有(you)(you)廠家生(sheng)產，并經十幾家煤礦試(shi)用(yong)(yong)(yong)，可替代同類進(jin)口產品(pin)。膠(jiao)(jiao)管(guan)膠(jiao)(jiao)帶的(de)(de)(de)發展，膠(jiao)(jiao)管(guan)發展的(de)(de)(de)重點是(shi)提(ti)升汽車用(yong)(yong)(yong)膠(jiao)(jiao)管(guan)制造技術(shu)和(he)產品(pin)性能，填補(bu)國內(nei)高(gao)(gao)檔汽車用(yong)(yong)(yong)膠(jiao)(jiao)管(guan)膠(jiao)(jiao)帶的(de)(de)(de)空白。加快(kuai)高(gao)(gao)壓(ya)(ya)鋼(gang)絲編織(zhi)膠(jiao)(jiao)管(guan)膠(jiao)(jiao)帶和(he)纏繞膠(jiao)(jiao)管(guan)的(de)(de)(de)更新換代速(su)度，提(ti)高(gao)(gao)脈(mo)沖壽命。
