大連膠管在使用前，必須先把膠管內壁滑石粉吹除干(gan)凈，防止焊割炬(ju)的通道被(bei)堵塞。在使用(yong)(yong)(yong)中(zhong)應避免受外(wai)界(jie)擠壓(ya)和(he)機械(xie)損傷，也(ye)不(bu)得(de)與上述影響(xiang)膠(jiao)管(guan)(guan)(guan)(guan)(guan)質量的物質接觸，不(bu)得(de)將管(guan)(guan)(guan)(guan)(guan)身折疊(die)。煤(mei)(mei)(mei)(mei)炭工(gong)業(ye)用(yong)(yong)(yong)油管(guan)(guan)(guan)(guan)(guan)主要有(you)液壓(ya)支(zhi)架膠(jiao)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)。近年來，有(you)些煤(mei)(mei)(mei)(mei)礦液壓(ya)支(zhi)架的壓(ya)力要求(qiu)已(yi)經提高，一(yi)部分(fen)鋼(gang)絲(si)編織(zhi)(zhi)膠(jiao)管(guan)(guan)(guan)(guan)(guan)不(bu)能滿(man)足其(qi)性能要求(qiu)，要求(qiu)改用(yong)(yong)(yong)鋼(gang)絲(si)纏繞油管(guan)(guan)(guan)(guan)(guan)。此外(wai)，為防止煤(mei)(mei)(mei)(mei)礦井下采(cai)煤(mei)(mei)(mei)(mei)過程中(zhong)煤(mei)(mei)(mei)(mei)塵污染(ran)和(he)提高生產(chan)(chan)安全性，增加了煤(mei)(mei)(mei)(mei)礦用(yong)(yong)(yong)油管(guan)(guan)(guan)(guan)(guan)的品種，如煤(mei)(mei)(mei)(mei)層探水封孔器伸(shen)縮油管(guan)(guan)(guan)(guan)(guan)，用(yong)(yong)(yong)于(yu)煤(mei)(mei)(mei)(mei)礦井下工(gong)作面綜采(cai)前對(dui)煤(mei)(mei)(mei)(mei)層進行注水、注漿等作業(ye)。據報道，國內已(yi)有(you)廠(chang)家生產(chan)(chan)，并(bing)經十幾家煤(mei)(mei)(mei)(mei)礦試(shi)用(yong)(yong)(yong)，可(ke)替(ti)代同類進口產(chan)(chan)品。膠(jiao)管(guan)(guan)(guan)(guan)(guan)膠(jiao)帶(dai)的發(fa)展，膠(jiao)管(guan)(guan)(guan)(guan)(guan)發(fa)展的重點是提升汽車用(yong)(yong)(yong)膠(jiao)管(guan)(guan)(guan)(guan)(guan)制(zhi)造技(ji)術(shu)和(he)產(chan)(chan)品性能，填補(bu)國內高檔汽車用(yong)(yong)(yong)膠(jiao)管(guan)(guan)(guan)(guan)(guan)膠(jiao)帶(dai)的空白。加快高壓(ya)鋼(gang)絲(si)編織(zhi)(zhi)膠(jiao)管(guan)(guan)(guan)(guan)(guan)膠(jiao)帶(dai)和(he)纏繞膠(jiao)管(guan)(guan)(guan)(guan)(guan)的更(geng)新(xin)換代速度，提高脈(mo)沖壽(shou)命。
