膠管近年來，開始采用(yong)(yong)熱(re)塑性橡(xiang)膠(jiao)，如(ru)熱(re)塑性聚氨(an)酯橡(xiang)膠(jiao)、聚酯橡(xiang)膠(jiao)等(deng)。膠(jiao)管(guan)(guan)(guan)(guan)因易(yi)彎曲、能緩沖、重量(liang)輕(qing)及安裝使(shi)(shi)用(yong)(yong)方便(bian)等(deng)優點，用(yong)(yong)途十分(fen)廣泛(fan)，如(ru)農(nong)業上排(pai)灌農(nong)田、港灣(wan)疏浚中(zhong)吸(xi)排(pai)泥漿，飛(fei)機、坦(tan)克、汽車及許多機械裝備中(zhong)的(de)液壓(ya)(ya)系(xi)統、氣(qi)(qi)動系(xi)統、燃(ran)油系(xi)統均使(shi)(shi)用(yong)(yong)許多膠(jiao)管(guan)(guan)(guan)(guan)。氣(qi)(qi)割操作需要較大的(de)氧氣(qi)(qi)輸出量(liang)，因此(ci)(ci)與(yu)氧氣(qi)(qi)表(biao)高(gao)壓(ya)(ya)端連接(jie)的(de)氣(qi)(qi)瓶（或氧氣(qi)(qi)管(guan)(guan)(guan)(guan)道）閥門應全(quan)打開，以便(bian)保(bao)證提供足夠的(de)流量(liang)和穩定的(de)壓(ya)(ya)力(li)，防止(zhi)(zhi)低壓(ya)(ya)表(biao)雖已表(biao)示工(gong)作壓(ya)(ya)力(li)，但使(shi)(shi)用(yong)(yong)時壓(ya)(ya)力(li)突然下降，此(ci)(ci)時容易(yi)發生(sheng)回(hui)火(huo)，并可能倒燃(ran)進(jin)入氧氣(qi)(qi)膠(jiao)管(guan)(guan)(guan)(guan)而(er)引(yin)起爆(bao)炸。在保(bao)存(cun)、運輸和使(shi)(shi)用(yong)(yong)膠(jiao)管(guan)(guan)(guan)(guan)時必須(xu)注意(yi)維(wei)護，保(bao)持(chi)膠(jiao)管(guan)(guan)(guan)(guan)的(de)清潔和不受損壞。例如(ru)避免陽光照射，雨雪浸淋、防止(zhi)(zhi)與(yu)酸、堿、油類及其他(ta)有機溶劑等(deng)影(ying)響膠(jiao)管(guan)(guan)(guan)(guan)質量(liang)的(de)物質接(jie)觸(chu)。存(cun)放(fang)溫(wen)度為-15～40℃，距離熱(re)源應不小于1m.如(ru)果由(you)于保(bao)存(cun)和使(shi)(shi)用(yong)(yong)時維(wei)護不善，或膠(jiao)管(guan)(guan)(guan)(guan)使(shi)(shi)用(yong)(yong)日久老(lao)化脆硬，這些膠(jiao)管(guan)(guan)(guan)(guan)內的(de)硫磺質被分(fen)解出來，常常會因此(ci)(ci)引(yin)起回(hui)火(huo)爆(bao)炸事故。
