膠管近年來(lai)，開(kai)始采用(yong)(yong)(yong)(yong)熱(re)塑性橡膠(jiao)(jiao)，如(ru)熱(re)塑性聚氨(an)酯(zhi)橡膠(jiao)(jiao)、聚酯(zhi)橡膠(jiao)(jiao)等。膠(jiao)(jiao)管因(yin)(yin)易(yi)彎曲、能緩沖(chong)、重量(liang)輕及(ji)安裝(zhuang)使(shi)(shi)用(yong)(yong)(yong)(yong)方便等優點，用(yong)(yong)(yong)(yong)途十分廣泛，如(ru)農(nong)業上(shang)排灌(guan)農(nong)田、港灣疏浚中吸排泥漿，飛機、坦克、汽車及(ji)許多機械裝(zhuang)備中的液壓系(xi)統(tong)、氣(qi)動系(xi)統(tong)、燃油系(xi)統(tong)均使(shi)(shi)用(yong)(yong)(yong)(yong)許多膠(jiao)(jiao)管。氣(qi)割操作需要較大的氧(yang)氣(qi)輸(shu)出量(liang)，因(yin)(yin)此與氧(yang)氣(qi)表(biao)高壓端連(lian)接的氣(qi)瓶（或(huo)氧(yang)氣(qi)管道）閥(fa)門應全打(da)開(kai)，以便保(bao)(bao)證(zheng)提供足(zu)夠的流量(liang)和(he)(he)穩定的壓力(li)，防(fang)止低壓表(biao)雖已表(biao)示工(gong)作壓力(li)，但使(shi)(shi)用(yong)(yong)(yong)(yong)時(shi)壓力(li)突然下降，此時(shi)容易(yi)發生(sheng)回(hui)火(huo)，并(bing)可能倒燃進(jin)入氧(yang)氣(qi)膠(jiao)(jiao)管而引起(qi)爆炸(zha)。在保(bao)(bao)存、運輸(shu)和(he)(he)使(shi)(shi)用(yong)(yong)(yong)(yong)膠(jiao)(jiao)管時(shi)必須注意維護，保(bao)(bao)持膠(jiao)(jiao)管的清潔和(he)(he)不(bu)受損壞。例(li)如(ru)避(bi)免(mian)陽光照(zhao)射，雨雪浸淋、防(fang)止與酸、堿、油類及(ji)其(qi)他有機溶(rong)劑等影響膠(jiao)(jiao)管質(zhi)量(liang)的物質(zhi)接觸。存放溫度為-15～40℃，距離熱(re)源(yuan)應不(bu)小于1m.如(ru)果由于保(bao)(bao)存和(he)(he)使(shi)(shi)用(yong)(yong)(yong)(yong)時(shi)維護不(bu)善，或(huo)膠(jiao)(jiao)管使(shi)(shi)用(yong)(yong)(yong)(yong)日(ri)久老(lao)化(hua)脆硬，這些膠(jiao)(jiao)管內的硫磺質(zhi)被分解出來(lai)，常(chang)常(chang)會(hui)因(yin)(yin)此引起(qi)回(hui)火(huo)爆炸(zha)事(shi)故。
