膠管近年來(lai)，開始采用(yong)(yong)熱(re)(re)塑性橡(xiang)膠(jiao)(jiao)(jiao)，如(ru)(ru)熱(re)(re)塑性聚氨酯(zhi)橡(xiang)膠(jiao)(jiao)(jiao)、聚酯(zhi)橡(xiang)膠(jiao)(jiao)(jiao)等(deng)。膠(jiao)(jiao)(jiao)管因(yin)易彎曲(qu)、能(neng)緩沖、重(zhong)量(liang)輕及(ji)安裝使(shi)(shi)用(yong)(yong)方便等(deng)優點，用(yong)(yong)途(tu)十分廣泛，如(ru)(ru)農業(ye)上排灌農田、港灣疏浚(jun)中(zhong)吸排泥漿，飛機(ji)、坦克、汽車及(ji)許多機(ji)械(xie)裝備(bei)中(zhong)的液壓系(xi)(xi)統(tong)(tong)、氣(qi)(qi)動系(xi)(xi)統(tong)(tong)、燃油(you)系(xi)(xi)統(tong)(tong)均使(shi)(shi)用(yong)(yong)許多膠(jiao)(jiao)(jiao)管。氣(qi)(qi)割操作(zuo)(zuo)需要(yao)較(jiao)大的氧(yang)氣(qi)(qi)輸(shu)(shu)出(chu)量(liang)，因(yin)此(ci)與氧(yang)氣(qi)(qi)表高(gao)壓端連接的氣(qi)(qi)瓶（或(huo)氧(yang)氣(qi)(qi)管道）閥門(men)應(ying)全打開，以(yi)便保(bao)(bao)證提供(gong)足夠的流量(liang)和(he)(he)(he)穩定的壓力，防(fang)止(zhi)低(di)壓表雖(sui)已表示工作(zuo)(zuo)壓力，但使(shi)(shi)用(yong)(yong)時壓力突然下降，此(ci)時容(rong)易發生回火，并(bing)可(ke)能(neng)倒燃進入(ru)氧(yang)氣(qi)(qi)膠(jiao)(jiao)(jiao)管而引(yin)起爆炸。在保(bao)(bao)存(cun)(cun)、運輸(shu)(shu)和(he)(he)(he)使(shi)(shi)用(yong)(yong)膠(jiao)(jiao)(jiao)管時必須注意維護，保(bao)(bao)持膠(jiao)(jiao)(jiao)管的清潔(jie)和(he)(he)(he)不受損壞。例如(ru)(ru)避免陽(yang)光(guang)照射，雨雪(xue)浸(jin)淋(lin)、防(fang)止(zhi)與酸、堿、油(you)類及(ji)其他有(you)機(ji)溶(rong)劑(ji)等(deng)影響膠(jiao)(jiao)(jiao)管質量(liang)的物(wu)質接觸。存(cun)(cun)放(fang)溫度為-15～40℃，距離熱(re)(re)源應(ying)不小于1m.如(ru)(ru)果由于保(bao)(bao)存(cun)(cun)和(he)(he)(he)使(shi)(shi)用(yong)(yong)時維護不善(shan)，或(huo)膠(jiao)(jiao)(jiao)管使(shi)(shi)用(yong)(yong)日久老化脆(cui)硬(ying)，這些膠(jiao)(jiao)(jiao)管內的硫磺質被分解出(chu)來(lai)，常常會因(yin)此(ci)引(yin)起回火爆炸事(shi)故。
