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(han)割炬的通道被堵塞。在使用(yong)中應避免(mian)受外界(jie)擠(ji)壓和(he)機(ji)械損(sun)傷，也不得與上述影響膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)質(zhi)量的物質(zhi)接觸，不得將(jiang)管(guan)(guan)(guan)(guan)身(shen)折疊。煤(mei)(mei)炭工業(ye)用(yong)油(you)管(guan)(guan)(guan)(guan)主要(yao)(yao)有(you)液壓支(zhi)架(jia)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)。近年(nian)來，有(you)些煤(mei)(mei)礦(kuang)(kuang)液壓支(zhi)架(jia)的壓力(li)要(yao)(yao)求(qiu)已經提(ti)高(gao)，一部(bu)分鋼絲(si)(si)編織膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)不能(neng)滿足其(qi)性(xing)能(neng)要(yao)(yao)求(qiu)，要(yao)(yao)求(qiu)改用(yong)鋼絲(si)(si)纏(chan)繞油(you)管(guan)(guan)(guan)(guan)。此(ci)外，為防止煤(mei)(mei)礦(kuang)(kuang)井(jing)下采(cai)(cai)煤(mei)(mei)過程(cheng)中煤(mei)(mei)塵污染(ran)和(he)提(ti)高(gao)生產安全性(xing)，增(zeng)加了煤(mei)(mei)礦(kuang)(kuang)用(yong)油(you)管(guan)(guan)(guan)(guan)的品種(zhong)，如(ru)煤(mei)(mei)層探水(shui)封孔器伸縮油(you)管(guan)(guan)(guan)(guan)，用(yong)于煤(mei)(mei)礦(kuang)(kuang)井(jing)下工作面綜采(cai)(cai)前(qian)對煤(mei)(mei)層進行注水(shui)、注漿等作業(ye)。據(ju)報道，國內已有(you)廠家(jia)生產，并經十幾(ji)家(jia)煤(mei)(mei)礦(kuang)(kuang)試用(yong)，可替代同類(lei)進口產品。膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶的發(fa)展，膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)發(fa)展的重(zhong)點是提(ti)升汽車用(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)制造技術和(he)產品性(xing)能(neng)，填補國內高(gao)檔汽車用(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶的空白。加快高(gao)壓鋼絲(si)(si)編織膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶和(he)纏(chan)繞膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)的更新換代速度，提(ti)高(gao)脈沖壽命。
