膠管近年(nian)來，開始采用(yong)(yong)(yong)(yong)熱塑性(xing)橡(xiang)膠(jiao)(jiao)(jiao)，如(ru)熱塑性(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)因易彎曲(qu)、能緩沖、重量(liang)(liang)輕(qing)及安裝使(shi)(shi)用(yong)(yong)(yong)(yong)方便等優點(dian)，用(yong)(yong)(yong)(yong)途(tu)十分廣泛，如(ru)農業上排灌農田、港(gang)灣疏浚(jun)中吸排泥(ni)漿，飛機、坦克、汽車(che)及許(xu)多機械裝備(bei)中的液(ye)壓系(xi)統、氣(qi)(qi)動(dong)系(xi)統、燃油系(xi)統均使(shi)(shi)用(yong)(yong)(yong)(yong)許(xu)多膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)。氣(qi)(qi)割操作(zuo)需要較大(da)的氧(yang)氣(qi)(qi)輸出(chu)量(liang)(liang)，因此與(yu)氧(yang)氣(qi)(qi)表(biao)高壓端連接的氣(qi)(qi)瓶（或(huo)氧(yang)氣(qi)(qi)管(guan)(guan)(guan)道）閥門應全打開，以(yi)便保證(zheng)提供足夠的流量(liang)(liang)和穩定的壓力，防止低壓表(biao)雖已(yi)表(biao)示工作(zuo)壓力，但使(shi)(shi)用(yong)(yong)(yong)(yong)時壓力突(tu)然下(xia)降，此時容易發(fa)生回(hui)火，并可能倒燃進(jin)入(ru)氧(yang)氣(qi)(qi)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)而(er)引起爆炸。在保存(cun)、運輸和使(shi)(shi)用(yong)(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)時必須注意維(wei)護(hu)，保持膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)的清潔(jie)和不受損(sun)壞。例如(ru)避免陽光(guang)照射，雨雪浸淋、防止與(yu)酸、堿、油類(lei)及其他有機溶劑等影(ying)響膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)質量(liang)(liang)的物質接觸。存(cun)放(fang)溫度為(wei)-15～40℃，距離熱源應不小于1m.如(ru)果由于保存(cun)和使(shi)(shi)用(yong)(yong)(yong)(yong)時維(wei)護(hu)不善，或(huo)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)使(shi)(shi)用(yong)(yong)(yong)(yong)日(ri)久老(lao)化(hua)脆硬，這些(xie)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)內的硫磺質被分解(jie)出(chu)來，常(chang)常(chang)會因此引起回(hui)火爆炸事(shi)故。
