膠管近(jin)年來，開始(shi)采用(yong)(yong)(yong)熱(re)塑性橡(xiang)膠(jiao)(jiao)，如熱(re)塑性聚(ju)氨(an)酯橡(xiang)膠(jiao)(jiao)、聚(ju)酯橡(xiang)膠(jiao)(jiao)等(deng)。膠(jiao)(jiao)管(guan)因易彎曲、能(neng)緩沖、重量輕及(ji)(ji)安裝(zhuang)(zhuang)使(shi)用(yong)(yong)(yong)方便(bian)等(deng)優點，用(yong)(yong)(yong)途十(shi)分廣泛，如農業上(shang)排(pai)灌(guan)農田、港(gang)灣疏(shu)浚中(zhong)吸排(pai)泥漿(jiang)，飛機、坦(tan)克、汽車(che)及(ji)(ji)許多機械裝(zhuang)(zhuang)備(bei)中(zhong)的(de)液壓(ya)系(xi)統(tong)(tong)、氣(qi)(qi)動系(xi)統(tong)(tong)、燃(ran)油系(xi)統(tong)(tong)均使(shi)用(yong)(yong)(yong)許多膠(jiao)(jiao)管(guan)。氣(qi)(qi)割操作需要較(jiao)大的(de)氧(yang)(yang)氣(qi)(qi)輸出量，因此(ci)與(yu)氧(yang)(yang)氣(qi)(qi)表(biao)高壓(ya)端連接的(de)氣(qi)(qi)瓶（或氧(yang)(yang)氣(qi)(qi)管(guan)道）閥(fa)門(men)應全打(da)開，以便(bian)保證(zheng)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(biao)雖已(yi)表(biao)示工(gong)作壓(ya)力(li)，但使(shi)用(yong)(yong)(yong)時壓(ya)力(li)突然下降，此(ci)時容易發(fa)生回(hui)(hui)火(huo)(huo)，并可能(neng)倒燃(ran)進入氧(yang)(yang)氣(qi)(qi)膠(jiao)(jiao)管(guan)而引(yin)起爆炸。在保存(cun)、運輸和使(shi)用(yong)(yong)(yong)膠(jiao)(jiao)管(guan)時必須注(zhu)意維護，保持膠(jiao)(jiao)管(guan)的(de)清潔和不(bu)受(shou)損壞(huai)。例如避免(mian)陽光照射，雨雪浸淋、防止與(yu)酸、堿、油類及(ji)(ji)其他有機溶劑(ji)等(deng)影響膠(jiao)(jiao)管(guan)質量的(de)物質接觸(chu)。存(cun)放(fang)溫度為-15～40℃，距離熱(re)源應不(bu)小于(yu)1m.如果由于(yu)保存(cun)和使(shi)用(yong)(yong)(yong)時維護不(bu)善(shan)，或膠(jiao)(jiao)管(guan)使(shi)用(yong)(yong)(yong)日(ri)久(jiu)老化脆硬，這(zhe)些膠(jiao)(jiao)管(guan)內(nei)的(de)硫磺質被(bei)分解出來，常(chang)常(chang)會(hui)因此(ci)引(yin)起回(hui)(hui)火(huo)(huo)爆炸事故。
