大連膠管在使用前，必須先把膠管內壁滑(hua)石(shi)粉吹(chui)除(chu)干凈，防止(zhi)焊割炬的(de)通道被堵(du)塞。在(zai)使用(yong)(yong)中應(ying)避免受外(wai)界擠壓(ya)(ya)和(he)機械(xie)損傷，也不(bu)得與上述影響膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)質量(liang)的(de)物質接觸(chu)，不(bu)得將管(guan)(guan)身折疊。煤(mei)(mei)(mei)(mei)炭工業用(yong)(yong)油(you)管(guan)(guan)主(zhu)要(yao)(yao)有(you)液(ye)壓(ya)(ya)支架膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)管(guan)(guan)。近年(nian)來，有(you)些煤(mei)(mei)(mei)(mei)礦液(ye)壓(ya)(ya)支架的(de)壓(ya)(ya)力要(yao)(yao)求已經(jing)提高(gao)，一部分鋼(gang)絲編(bian)織膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)不(bu)能(neng)滿足其性(xing)能(neng)要(yao)(yao)求，要(yao)(yao)求改用(yong)(yong)鋼(gang)絲纏繞油(you)管(guan)(guan)。此(ci)外(wai)，為防止(zhi)煤(mei)(mei)(mei)(mei)礦井(jing)下采煤(mei)(mei)(mei)(mei)過程(cheng)中煤(mei)(mei)(mei)(mei)塵污染和(he)提高(gao)生產安全性(xing)，增加了煤(mei)(mei)(mei)(mei)礦用(yong)(yong)油(you)管(guan)(guan)的(de)品(pin)種，如煤(mei)(mei)(mei)(mei)層探(tan)水(shui)(shui)封(feng)孔器伸縮油(you)管(guan)(guan)，用(yong)(yong)于(yu)煤(mei)(mei)(mei)(mei)礦井(jing)下工作面(mian)綜采前對煤(mei)(mei)(mei)(mei)層進行注(zhu)水(shui)(shui)、注(zhu)漿(jiang)等作業。據報(bao)道，國內已有(you)廠(chang)家生產，并經(jing)十幾家煤(mei)(mei)(mei)(mei)礦試用(yong)(yong)，可替代同類(lei)進口產品(pin)。膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶的(de)發(fa)展，膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)發(fa)展的(de)重點是提升汽車用(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)制造技術和(he)產品(pin)性(xing)能(neng)，填補國內高(gao)檔汽車用(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶的(de)空白(bai)。加快高(gao)壓(ya)(ya)鋼(gang)絲編(bian)織膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)膠(jiao)(jiao)(jiao)(jiao)帶和(he)纏繞膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)的(de)更新換代速度，提高(gao)脈沖壽命。
