膠管近年來，開始采用(yong)(yong)(yong)熱(re)塑性(xing)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，如熱(re)塑性(xing)聚氨酯橡(xiang)膠(jiao)(jiao)(jiao)(jiao)、聚酯橡(xiang)膠(jiao)(jiao)(jiao)(jiao)等。膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)因(yin)易彎曲、能(neng)緩(huan)沖、重量輕及安裝使用(yong)(yong)(yong)方便等優(you)點，用(yong)(yong)(yong)途(tu)十分廣泛，如農(nong)業上排灌農(nong)田、港灣疏浚(jun)中吸排泥漿，飛機(ji)、坦克、汽車及許多機(ji)械(xie)裝備中的(de)(de)液(ye)壓(ya)(ya)系統(tong)、氣動系統(tong)、燃油系統(tong)均使用(yong)(yong)(yong)許多膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)。氣割操作(zuo)需(xu)要較大的(de)(de)氧(yang)(yang)氣輸出(chu)量，因(yin)此與氧(yang)(yang)氣表高壓(ya)(ya)端連接的(de)(de)氣瓶（或氧(yang)(yang)氣管(guan)(guan)(guan)道）閥門應(ying)全打開，以便保(bao)證(zheng)提(ti)供(gong)足(zu)夠的(de)(de)流量和穩定的(de)(de)壓(ya)(ya)力，防止低(di)壓(ya)(ya)表雖已表示工(gong)作(zuo)壓(ya)(ya)力，但使用(yong)(yong)(yong)時(shi)壓(ya)(ya)力突然下降，此時(shi)容易發生回火(huo)(huo)，并可能(neng)倒(dao)燃進入(ru)氧(yang)(yang)氣膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)而引起爆炸。在保(bao)存(cun)、運輸和使用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)時(shi)必須注意維護，保(bao)持膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)的(de)(de)清潔和不受損壞。例如避免陽光照射(she)，雨雪浸淋、防止與酸、堿、油類及其他有機(ji)溶劑(ji)等影響膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)質量的(de)(de)物質接觸。存(cun)放(fang)溫度為-15～40℃，距(ju)離熱(re)源應(ying)不小于1m.如果由于保(bao)存(cun)和使用(yong)(yong)(yong)時(shi)維護不善(shan)，或膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)使用(yong)(yong)(yong)日(ri)久老化(hua)脆硬(ying)，這(zhe)些膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)內(nei)的(de)(de)硫磺質被分解出(chu)來，常(chang)常(chang)會因(yin)此引起回火(huo)(huo)爆炸事故。
