膠管近年來，開(kai)始(shi)采用(yong)(yong)(yong)熱(re)塑性橡(xiang)膠，如(ru)熱(re)塑性聚(ju)氨酯(zhi)橡(xiang)膠、聚(ju)酯(zhi)橡(xiang)膠等(deng)。膠管(guan)(guan)因(yin)(yin)易彎曲、能(neng)(neng)緩沖、重(zhong)量輕(qing)及(ji)安裝(zhuang)使(shi)(shi)用(yong)(yong)(yong)方便等(deng)優點，用(yong)(yong)(yong)途十(shi)分廣泛，如(ru)農(nong)(nong)業上排(pai)灌(guan)農(nong)(nong)田、港灣(wan)疏浚中(zhong)吸排(pai)泥漿，飛機(ji)、坦克、汽車及(ji)許(xu)多機(ji)械裝(zhuang)備(bei)中(zhong)的(de)液壓(ya)(ya)系統(tong)(tong)、氣(qi)動系統(tong)(tong)、燃油(you)(you)系統(tong)(tong)均使(shi)(shi)用(yong)(yong)(yong)許(xu)多膠管(guan)(guan)。氣(qi)割操(cao)作(zuo)(zuo)需要較大的(de)氧氣(qi)輸(shu)出量，因(yin)(yin)此(ci)與(yu)(yu)氧氣(qi)表高(gao)壓(ya)(ya)端連接(jie)的(de)氣(qi)瓶(ping)（或氧氣(qi)管(guan)(guan)道）閥門應(ying)全打開(kai)，以便保(bao)證提供足夠的(de)流量和(he)穩定的(de)壓(ya)(ya)力，防(fang)止低壓(ya)(ya)表雖已表示工作(zuo)(zuo)壓(ya)(ya)力，但使(shi)(shi)用(yong)(yong)(yong)時壓(ya)(ya)力突然下(xia)降(jiang)，此(ci)時容易發生回(hui)火，并(bing)可能(neng)(neng)倒(dao)燃進入氧氣(qi)膠管(guan)(guan)而引起爆炸。在保(bao)存、運(yun)輸(shu)和(he)使(shi)(shi)用(yong)(yong)(yong)膠管(guan)(guan)時必須注意維護，保(bao)持(chi)膠管(guan)(guan)的(de)清潔和(he)不(bu)(bu)受損壞。例如(ru)避(bi)免(mian)陽(yang)光照射，雨雪浸淋、防(fang)止與(yu)(yu)酸、堿(jian)、油(you)(you)類及(ji)其他有機(ji)溶劑等(deng)影響膠管(guan)(guan)質量的(de)物質接(jie)觸。存放溫(wen)度(du)為(wei)-15～40℃，距離(li)熱(re)源應(ying)不(bu)(bu)小于1m.如(ru)果由于保(bao)存和(he)使(shi)(shi)用(yong)(yong)(yong)時維護不(bu)(bu)善(shan)，或膠管(guan)(guan)使(shi)(shi)用(yong)(yong)(yong)日久老化(hua)脆硬，這些膠管(guan)(guan)內的(de)硫磺質被(bei)分解出來，常(chang)常(chang)會因(yin)(yin)此(ci)引起回(hui)火爆炸事故。
