膠管近年來，開始采用(yong)(yong)(yong)熱(re)塑性橡膠(jiao)(jiao)(jiao)(jiao)，如熱(re)塑性聚氨酯橡膠(jiao)(jiao)(jiao)(jiao)、聚酯橡膠(jiao)(jiao)(jiao)(jiao)等。膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)因易彎曲(qu)、能緩(huan)沖(chong)、重量(liang)(liang)輕及安裝(zhuang)(zhuang)使(shi)用(yong)(yong)(yong)方便等優點，用(yong)(yong)(yong)途十分廣泛(fan)，如農業上排(pai)灌農田、港灣疏浚中吸排(pai)泥漿，飛機(ji)、坦(tan)克、汽(qi)車及許多機(ji)械裝(zhuang)(zhuang)備(bei)中的(de)液壓(ya)系統(tong)(tong)、氣(qi)(qi)(qi)動系統(tong)(tong)、燃(ran)油(you)系統(tong)(tong)均使(shi)用(yong)(yong)(yong)許多膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)。氣(qi)(qi)(qi)割操作(zuo)需要較大(da)的(de)氧(yang)氣(qi)(qi)(qi)輸(shu)出量(liang)(liang)，因此(ci)與氧(yang)氣(qi)(qi)(qi)表高(gao)壓(ya)端連接(jie)的(de)氣(qi)(qi)(qi)瓶（或(huo)氧(yang)氣(qi)(qi)(qi)管(guan)(guan)(guan)道）閥門應全打開，以便保(bao)證提供足夠(gou)的(de)流量(liang)(liang)和穩(wen)定的(de)壓(ya)力(li)(li)，防止低壓(ya)表雖已表示工作(zuo)壓(ya)力(li)(li)，但使(shi)用(yong)(yong)(yong)時(shi)壓(ya)力(li)(li)突然下降(jiang)，此(ci)時(shi)容易發生回火，并可能倒燃(ran)進入(ru)氧(yang)氣(qi)(qi)(qi)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)而引起爆炸。在保(bao)存、運輸(shu)和使(shi)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)時(shi)必須注意(yi)維(wei)護，保(bao)持膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)的(de)清潔(jie)和不受損(sun)壞。例如避免陽光照射，雨雪浸淋(lin)、防止與酸、堿、油(you)類及其他有機(ji)溶劑等影(ying)響膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)質量(liang)(liang)的(de)物質接(jie)觸。存放溫度為-15～40℃，距離(li)熱(re)源應不小于(yu)1m.如果由(you)于(yu)保(bao)存和使(shi)用(yong)(yong)(yong)時(shi)維(wei)護不善，或(huo)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)使(shi)用(yong)(yong)(yong)日久老化脆硬，這些膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)內的(de)硫磺質被分解出來，常常會(hui)因此(ci)引起回火爆炸事故。
