膠管近年(nian)來，開始采用(yong)(yong)(yong)熱塑性橡膠(jiao)(jiao)，如(ru)熱塑性聚氨酯(zhi)橡膠(jiao)(jiao)、聚酯(zhi)橡膠(jiao)(jiao)等(deng)。膠(jiao)(jiao)管(guan)(guan)(guan)因(yin)易(yi)彎曲(qu)、能緩沖、重量輕及安裝使用(yong)(yong)(yong)方(fang)便(bian)等(deng)優點，用(yong)(yong)(yong)途(tu)十分(fen)廣泛，如(ru)農(nong)業(ye)上(shang)排灌農(nong)田、港灣疏浚(jun)中(zhong)吸排泥漿，飛機(ji)(ji)(ji)、坦(tan)克(ke)、汽(qi)車(che)及許(xu)多(duo)機(ji)(ji)(ji)械(xie)裝備中(zhong)的(de)液(ye)壓(ya)(ya)(ya)系統、氣(qi)動系統、燃油系統均使用(yong)(yong)(yong)許(xu)多(duo)膠(jiao)(jiao)管(guan)(guan)(guan)。氣(qi)割操作需要較大的(de)氧(yang)(yang)氣(qi)輸(shu)出量，因(yin)此與氧(yang)(yang)氣(qi)表高壓(ya)(ya)(ya)端連接的(de)氣(qi)瓶（或(huo)氧(yang)(yang)氣(qi)管(guan)(guan)(guan)道）閥(fa)門(men)應(ying)(ying)全打開，以便(bian)保證(zheng)提供足(zu)夠的(de)流量和穩(wen)定的(de)壓(ya)(ya)(ya)力，防止低(di)壓(ya)(ya)(ya)表雖已表示工作壓(ya)(ya)(ya)力，但使用(yong)(yong)(yong)時壓(ya)(ya)(ya)力突然下降，此時容易(yi)發生回火(huo)(huo)，并可能倒燃進入氧(yang)(yang)氣(qi)膠(jiao)(jiao)管(guan)(guan)(guan)而引起爆炸(zha)。在保存(cun)、運輸(shu)和使用(yong)(yong)(yong)膠(jiao)(jiao)管(guan)(guan)(guan)時必須注意維護，保持膠(jiao)(jiao)管(guan)(guan)(guan)的(de)清潔和不受損(sun)壞。例如(ru)避免陽光照射，雨雪浸淋、防止與酸、堿、油類及其(qi)他有機(ji)(ji)(ji)溶劑等(deng)影響膠(jiao)(jiao)管(guan)(guan)(guan)質(zhi)(zhi)量的(de)物質(zhi)(zhi)接觸。存(cun)放溫度(du)為-15～40℃，距(ju)離熱源應(ying)(ying)不小于1m.如(ru)果由于保存(cun)和使用(yong)(yong)(yong)時維護不善，或(huo)膠(jiao)(jiao)管(guan)(guan)(guan)使用(yong)(yong)(yong)日久老化脆(cui)硬，這些(xie)膠(jiao)(jiao)管(guan)(guan)(guan)內的(de)硫磺(huang)質(zhi)(zhi)被(bei)分(fen)解出來，常常會因(yin)此引起回火(huo)(huo)爆炸(zha)事故。
