膠管近年來(lai)，開(kai)始采用(yong)(yong)熱塑性橡膠(jiao)(jiao)，如(ru)熱塑性聚氨酯橡膠(jiao)(jiao)、聚酯橡膠(jiao)(jiao)等(deng)。膠(jiao)(jiao)管(guan)(guan)(guan)因(yin)(yin)易彎(wan)曲、能緩沖、重量輕及安(an)裝(zhuang)使(shi)(shi)用(yong)(yong)方便等(deng)優點，用(yong)(yong)途十分廣泛，如(ru)農業(ye)上排(pai)灌農田(tian)、港灣疏浚中吸(xi)排(pai)泥漿，飛機、坦克、汽(qi)車及許(xu)多(duo)機械裝(zhuang)備(bei)中的(de)液壓(ya)系統(tong)(tong)、氣動系統(tong)(tong)、燃油系統(tong)(tong)均使(shi)(shi)用(yong)(yong)許(xu)多(duo)膠(jiao)(jiao)管(guan)(guan)(guan)。氣割操作(zuo)需要較大的(de)氧(yang)氣輸出(chu)量，因(yin)(yin)此(ci)與(yu)氧(yang)氣表高壓(ya)端連接的(de)氣瓶（或氧(yang)氣管(guan)(guan)(guan)道）閥(fa)門應全打開(kai)，以便保(bao)證提供足(zu)夠的(de)流(liu)量和穩定的(de)壓(ya)力(li)，防止低壓(ya)表雖已表示工作(zuo)壓(ya)力(li)，但使(shi)(shi)用(yong)(yong)時(shi)(shi)壓(ya)力(li)突然下(xia)降，此(ci)時(shi)(shi)容易發生回火，并可能倒燃進入氧(yang)氣膠(jiao)(jiao)管(guan)(guan)(guan)而引起(qi)爆炸。在保(bao)存、運輸和使(shi)(shi)用(yong)(yong)膠(jiao)(jiao)管(guan)(guan)(guan)時(shi)(shi)必(bi)須(xu)注意維(wei)護(hu)(hu)，保(bao)持膠(jiao)(jiao)管(guan)(guan)(guan)的(de)清(qing)潔和不受損壞。例(li)如(ru)避免(mian)陽光照射，雨雪浸(jin)淋、防止與(yu)酸、堿、油類及其他有機溶劑等(deng)影響膠(jiao)(jiao)管(guan)(guan)(guan)質(zhi)(zhi)(zhi)量的(de)物質(zhi)(zhi)(zhi)接觸。存放溫度為-15～40℃，距(ju)離熱源(yuan)應不小于1m.如(ru)果(guo)由于保(bao)存和使(shi)(shi)用(yong)(yong)時(shi)(shi)維(wei)護(hu)(hu)不善，或膠(jiao)(jiao)管(guan)(guan)(guan)使(shi)(shi)用(yong)(yong)日久(jiu)老化脆硬，這些膠(jiao)(jiao)管(guan)(guan)(guan)內的(de)硫磺質(zhi)(zhi)(zhi)被分解出(chu)來(lai)，常(chang)常(chang)會因(yin)(yin)此(ci)引起(qi)回火爆炸事(shi)故。
