膠管近年來(lai)，開始(shi)采用(yong)熱塑性(xing)(xing)橡(xiang)膠(jiao)(jiao)(jiao)，如(ru)熱塑性(xing)(xing)聚氨酯橡(xiang)膠(jiao)(jiao)(jiao)、聚酯橡(xiang)膠(jiao)(jiao)(jiao)等。膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)因易彎曲、能(neng)緩(huan)沖、重量輕及(ji)(ji)安裝使用(yong)方便(bian)等優點，用(yong)途十分廣泛，如(ru)農業(ye)上排(pai)灌農田、港灣疏浚中(zhong)吸排(pai)泥漿，飛機(ji)、坦克、汽車及(ji)(ji)許多機(ji)械裝備中(zhong)的液壓(ya)系(xi)統(tong)(tong)(tong)、氣動系(xi)統(tong)(tong)(tong)、燃油系(xi)統(tong)(tong)(tong)均(jun)使用(yong)許多膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)。氣割操作需要較大的氧氣輸(shu)出(chu)量，因此與氧氣表(biao)高壓(ya)端連接的氣瓶（或氧氣管(guan)(guan)(guan)(guan)道）閥門(men)應(ying)全(quan)打開，以便(bian)保證(zheng)提供足夠的流量和穩(wen)定的壓(ya)力，防(fang)止(zhi)低(di)壓(ya)表(biao)雖(sui)已表(biao)示工(gong)作壓(ya)力，但使用(yong)時(shi)壓(ya)力突然下降，此時(shi)容(rong)易發生回火(huo)，并可能(neng)倒(dao)燃進入(ru)氧氣膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)而引起爆(bao)炸(zha)。在(zai)保存、運輸(shu)和使用(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)時(shi)必須注意維護，保持(chi)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)的清潔(jie)和不受損壞。例如(ru)避(bi)免陽(yang)光照射(she)，雨雪浸(jin)淋、防(fang)止(zhi)與酸(suan)、堿、油類及(ji)(ji)其(qi)他有機(ji)溶劑等影響膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)質(zhi)量的物質(zhi)接觸。存放(fang)溫(wen)度為-15～40℃，距離熱源應(ying)不小(xiao)于(yu)(yu)1m.如(ru)果由于(yu)(yu)保存和使用(yong)時(shi)維護不善，或膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)使用(yong)日久老化脆硬，這些膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)內的硫(liu)磺質(zhi)被分解出(chu)來(lai)，常常會因此引起回火(huo)爆(bao)炸(zha)事(shi)故(gu)。
