大連膠管在使用前，必須先把膠管內壁滑石粉吹除干凈，防(fang)止焊割炬的通道(dao)被堵塞(sai)。在使用(yong)(yong)(yong)(yong)中應(ying)避免受(shou)外(wai)界擠壓(ya)和(he)機械(xie)損傷，也不得與(yu)上(shang)述影響膠(jiao)(jiao)(jiao)管(guan)質(zhi)量的物質(zhi)接觸，不得將管(guan)身折疊。煤(mei)(mei)炭(tan)工業用(yong)(yong)(yong)(yong)油(you)(you)(you)管(guan)主要有液壓(ya)支架膠(jiao)(jiao)(jiao)管(guan)管(guan)。近年來，有些煤(mei)(mei)礦液壓(ya)支架的壓(ya)力要求(qiu)已(yi)經提(ti)高，一(yi)部分鋼絲(si)編(bian)織(zhi)膠(jiao)(jiao)(jiao)管(guan)不能滿足(zu)其性能要求(qiu)，要求(qiu)改(gai)用(yong)(yong)(yong)(yong)鋼絲(si)纏繞油(you)(you)(you)管(guan)。此外(wai)，為防(fang)止煤(mei)(mei)礦井(jing)下(xia)采(cai)煤(mei)(mei)過程中煤(mei)(mei)塵污染和(he)提(ti)高生產安(an)全性，增加了煤(mei)(mei)礦用(yong)(yong)(yong)(yong)油(you)(you)(you)管(guan)的品(pin)種(zhong)，如(ru)煤(mei)(mei)層探水(shui)封(feng)孔器(qi)伸縮(suo)油(you)(you)(you)管(guan)，用(yong)(yong)(yong)(yong)于煤(mei)(mei)礦井(jing)下(xia)工作面綜采(cai)前對(dui)煤(mei)(mei)層進(jin)行注水(shui)、注漿(jiang)等作業。據報道(dao)，國(guo)內已(yi)有廠家生產，并經十幾家煤(mei)(mei)礦試用(yong)(yong)(yong)(yong)，可(ke)替代同類進(jin)口(kou)產品(pin)。膠(jiao)(jiao)(jiao)管(guan)膠(jiao)(jiao)(jiao)帶的發(fa)展，膠(jiao)(jiao)(jiao)管(guan)發(fa)展的重(zhong)點是提(ti)升汽車用(yong)(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)制造技(ji)術(shu)和(he)產品(pin)性能，填補國(guo)內高檔汽車用(yong)(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)膠(jiao)(jiao)(jiao)帶的空白。加快高壓(ya)鋼絲(si)編(bian)織(zhi)膠(jiao)(jiao)(jiao)管(guan)膠(jiao)(jiao)(jiao)帶和(he)纏繞膠(jiao)(jiao)(jiao)管(guan)的更新換代速度，提(ti)高脈沖壽命。
