大連膠管在使用前，必須先把膠管內壁滑石(shi)粉(fen)吹(chui)除干凈，防止(zhi)焊割炬的(de)(de)(de)(de)通道被堵(du)塞(sai)。在(zai)使用(yong)(yong)中應避免(mian)受外(wai)界(jie)擠壓和(he)機械(xie)損傷(shang)，也不得與上述影響(xiang)膠管(guan)(guan)(guan)質(zhi)(zhi)量的(de)(de)(de)(de)物質(zhi)(zhi)接觸，不得將管(guan)(guan)(guan)身折(zhe)疊(die)。煤炭工(gong)業(ye)用(yong)(yong)油管(guan)(guan)(guan)主要有液(ye)壓支架膠管(guan)(guan)(guan)管(guan)(guan)(guan)。近年來，有些(xie)煤礦液(ye)壓支架的(de)(de)(de)(de)壓力(li)要求(qiu)已經提高(gao)，一部(bu)分鋼(gang)絲編(bian)織(zhi)膠管(guan)(guan)(guan)不能(neng)(neng)滿足(zu)其性(xing)能(neng)(neng)要求(qiu)，要求(qiu)改用(yong)(yong)鋼(gang)絲纏(chan)繞油管(guan)(guan)(guan)。此(ci)外(wai)，為防止(zhi)煤礦井下(xia)采(cai)煤過程中煤塵污染(ran)和(he)提高(gao)生(sheng)產安全性(xing)，增加了煤礦用(yong)(yong)油管(guan)(guan)(guan)的(de)(de)(de)(de)品種(zhong)，如煤層(ceng)(ceng)探水封孔器伸縮油管(guan)(guan)(guan)，用(yong)(yong)于煤礦井下(xia)工(gong)作(zuo)面綜采(cai)前(qian)對煤層(ceng)(ceng)進(jin)行注水、注漿等(deng)作(zuo)業(ye)。據(ju)報道，國內已有廠家(jia)生(sheng)產，并經十幾(ji)家(jia)煤礦試用(yong)(yong)，可(ke)替代同類進(jin)口產品。膠管(guan)(guan)(guan)膠帶(dai)的(de)(de)(de)(de)發展，膠管(guan)(guan)(guan)發展的(de)(de)(de)(de)重點是提升汽車(che)用(yong)(yong)膠管(guan)(guan)(guan)制(zhi)造技術和(he)產品性(xing)能(neng)(neng)，填補國內高(gao)檔汽車(che)用(yong)(yong)膠管(guan)(guan)(guan)膠帶(dai)的(de)(de)(de)(de)空白(bai)。加快高(gao)壓鋼(gang)絲編(bian)織(zhi)膠管(guan)(guan)(guan)膠帶(dai)和(he)纏(chan)繞膠管(guan)(guan)(guan)的(de)(de)(de)(de)更新換代速度，提高(gao)脈(mo)沖(chong)壽(shou)命。
