膠管近年來，開始采用(yong)(yong)熱(re)(re)塑性橡膠，如(ru)熱(re)(re)塑性聚氨酯橡膠、聚酯橡膠等。膠管(guan)(guan)因易(yi)彎曲、能緩沖(chong)、重量輕及(ji)安裝使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)方便等優點，用(yong)(yong)途十分(fen)廣泛(fan)，如(ru)農業上排(pai)(pai)灌農田(tian)、港灣(wan)疏浚(jun)中吸排(pai)(pai)泥漿，飛機、坦(tan)克、汽車及(ji)許(xu)多機械裝備中的(de)(de)液壓(ya)(ya)(ya)(ya)系(xi)(xi)統、氣(qi)動系(xi)(xi)統、燃(ran)油系(xi)(xi)統均(jun)使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)許(xu)多膠管(guan)(guan)。氣(qi)割操作(zuo)需(xu)要較(jiao)大的(de)(de)氧氣(qi)輸(shu)出(chu)量，因此與氧氣(qi)表(biao)高壓(ya)(ya)(ya)(ya)端連接(jie)的(de)(de)氣(qi)瓶（或(huo)氧氣(qi)管(guan)(guan)道）閥門(men)應(ying)全(quan)打開，以便保(bao)證提供足夠的(de)(de)流量和(he)穩定的(de)(de)壓(ya)(ya)(ya)(ya)力，防(fang)止(zhi)低壓(ya)(ya)(ya)(ya)表(biao)雖已表(biao)示工作(zuo)壓(ya)(ya)(ya)(ya)力，但使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)時(shi)(shi)(shi)壓(ya)(ya)(ya)(ya)力突然下降，此時(shi)(shi)(shi)容(rong)易(yi)發生回(hui)火(huo)，并可(ke)能倒(dao)燃(ran)進入氧氣(qi)膠管(guan)(guan)而引起爆炸。在保(bao)存(cun)、運輸(shu)和(he)使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)膠管(guan)(guan)時(shi)(shi)(shi)必須注意維護，保(bao)持膠管(guan)(guan)的(de)(de)清潔和(he)不(bu)受損壞(huai)。例(li)如(ru)避免陽光照射，雨(yu)雪浸淋、防(fang)止(zhi)與酸、堿、油類及(ji)其他(ta)有機溶劑(ji)等影響膠管(guan)(guan)質(zhi)量的(de)(de)物質(zhi)接(jie)觸(chu)。存(cun)放溫(wen)度為-15～40℃，距離熱(re)(re)源(yuan)應(ying)不(bu)小于1m.如(ru)果由于保(bao)存(cun)和(he)使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)時(shi)(shi)(shi)維護不(bu)善，或(huo)膠管(guan)(guan)使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)日久老化(hua)脆硬，這些膠管(guan)(guan)內的(de)(de)硫磺質(zhi)被分(fen)解出(chu)來，常常會因此引起回(hui)火(huo)爆炸事故(gu)。
