膠管近年來，開始(shi)采用(yong)(yong)熱(re)塑(su)性(xing)橡(xiang)膠(jiao)，如(ru)熱(re)塑(su)性(xing)聚(ju)氨(an)酯橡(xiang)膠(jiao)、聚(ju)酯橡(xiang)膠(jiao)等。膠(jiao)管(guan)(guan)(guan)(guan)因易彎曲、能緩沖、重量輕(qing)及安裝(zhuang)使(shi)(shi)(shi)用(yong)(yong)方便等優點，用(yong)(yong)途十分(fen)廣泛，如(ru)農(nong)業上排灌農(nong)田、港灣疏浚中吸(xi)排泥漿，飛機、坦(tan)克、汽(qi)車及許多機械裝(zhuang)備(bei)中的(de)(de)液(ye)壓(ya)系(xi)統、氣(qi)(qi)動(dong)系(xi)統、燃油(you)系(xi)統均使(shi)(shi)(shi)用(yong)(yong)許多膠(jiao)管(guan)(guan)(guan)(guan)。氣(qi)(qi)割操作需要較大(da)的(de)(de)氧(yang)氣(qi)(qi)輸出量，因此與(yu)(yu)氧(yang)氣(qi)(qi)表高壓(ya)端(duan)連接(jie)的(de)(de)氣(qi)(qi)瓶（或(huo)氧(yang)氣(qi)(qi)管(guan)(guan)(guan)(guan)道(dao)）閥門應(ying)全打開，以便保證提(ti)供足夠的(de)(de)流(liu)量和(he)穩定(ding)的(de)(de)壓(ya)力(li)(li)，防止(zhi)低壓(ya)表雖已(yi)表示工(gong)作壓(ya)力(li)(li)，但使(shi)(shi)(shi)用(yong)(yong)時(shi)壓(ya)力(li)(li)突然下降，此時(shi)容易發生回火，并可能倒燃進入氧(yang)氣(qi)(qi)膠(jiao)管(guan)(guan)(guan)(guan)而引起爆炸(zha)。在保存、運輸和(he)使(shi)(shi)(shi)用(yong)(yong)膠(jiao)管(guan)(guan)(guan)(guan)時(shi)必須注意(yi)維(wei)護(hu)(hu)，保持(chi)膠(jiao)管(guan)(guan)(guan)(guan)的(de)(de)清潔和(he)不受(shou)損壞(huai)。例如(ru)避(bi)免陽光照射，雨雪浸淋、防止(zhi)與(yu)(yu)酸(suan)、堿(jian)、油(you)類(lei)及其(qi)他有機溶劑等影響(xiang)膠(jiao)管(guan)(guan)(guan)(guan)質(zhi)(zhi)量的(de)(de)物質(zhi)(zhi)接(jie)觸。存放溫度(du)為-15～40℃，距離熱(re)源應(ying)不小于1m.如(ru)果由于保存和(he)使(shi)(shi)(shi)用(yong)(yong)時(shi)維(wei)護(hu)(hu)不善，或(huo)膠(jiao)管(guan)(guan)(guan)(guan)使(shi)(shi)(shi)用(yong)(yong)日久老化脆硬，這些(xie)膠(jiao)管(guan)(guan)(guan)(guan)內的(de)(de)硫磺質(zhi)(zhi)被分(fen)解出來，常常會因此引起回火爆炸(zha)事(shi)故。
