大連膠管在使用前，必須先把膠管內(nei)壁滑石粉吹除干凈，防止焊(han)割炬的通道被堵塞。在使用(yong)(yong)中(zhong)應(ying)避免受外(wai)界擠壓和機械損(sun)傷(shang)，也不(bu)得(de)與上述影(ying)響(xiang)膠(jiao)管(guan)(guan)(guan)(guan)質量的物質接觸，不(bu)得(de)將管(guan)(guan)(guan)(guan)身折疊。煤(mei)(mei)(mei)炭工(gong)(gong)業用(yong)(yong)油(you)管(guan)(guan)(guan)(guan)主要有液壓支架(jia)膠(jiao)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)。近(jin)年來，有些煤(mei)(mei)(mei)礦液壓支架(jia)的壓力要求(qiu)(qiu)已經提高(gao)(gao)(gao)，一部分鋼絲(si)編織膠(jiao)管(guan)(guan)(guan)(guan)不(bu)能(neng)滿足其(qi)性能(neng)要求(qiu)(qiu)，要求(qiu)(qiu)改用(yong)(yong)鋼絲(si)纏繞油(you)管(guan)(guan)(guan)(guan)。此外(wai)，為(wei)防止煤(mei)(mei)(mei)礦井下采煤(mei)(mei)(mei)過程中(zhong)煤(mei)(mei)(mei)塵污染和提高(gao)(gao)(gao)生產安全性，增加了煤(mei)(mei)(mei)礦用(yong)(yong)油(you)管(guan)(guan)(guan)(guan)的品種，如煤(mei)(mei)(mei)層探水封(feng)孔器伸縮油(you)管(guan)(guan)(guan)(guan)，用(yong)(yong)于煤(mei)(mei)(mei)礦井下工(gong)(gong)作面綜(zong)采前對煤(mei)(mei)(mei)層進行(xing)注水、注漿等(deng)作業。據報道，國內(nei)已有廠家生產，并經十幾家煤(mei)(mei)(mei)礦試用(yong)(yong)，可替代(dai)同類進口產品。膠(jiao)管(guan)(guan)(guan)(guan)膠(jiao)帶的發展(zhan)，膠(jiao)管(guan)(guan)(guan)(guan)發展(zhan)的重點是提升汽車用(yong)(yong)膠(jiao)管(guan)(guan)(guan)(guan)制造技術和產品性能(neng)，填(tian)補國內(nei)高(gao)(gao)(gao)檔汽車用(yong)(yong)膠(jiao)管(guan)(guan)(guan)(guan)膠(jiao)帶的空白。加快(kuai)高(gao)(gao)(gao)壓鋼絲(si)編織膠(jiao)管(guan)(guan)(guan)(guan)膠(jiao)帶和纏繞膠(jiao)管(guan)(guan)(guan)(guan)的更新(xin)換(huan)代(dai)速度(du)，提高(gao)(gao)(gao)脈沖壽(shou)命。
