膠管近(jin)年來，開始采用(yong)熱塑(su)性(xing)橡(xiang)膠(jiao)(jiao)，如(ru)熱塑(su)性(xing)聚氨酯橡(xiang)膠(jiao)(jiao)、聚酯橡(xiang)膠(jiao)(jiao)等。膠(jiao)(jiao)管(guan)(guan)(guan)因易彎曲、能(neng)緩沖、重(zhong)量輕及安裝使(shi)用(yong)方便等優點，用(yong)途十(shi)分廣泛，如(ru)農(nong)(nong)業上(shang)排灌農(nong)(nong)田、港灣疏浚中吸排泥漿，飛機、坦克、汽車及許多機械裝備(bei)中的(de)(de)(de)液壓(ya)系(xi)統(tong)(tong)、氣(qi)(qi)動(dong)系(xi)統(tong)(tong)、燃油(you)系(xi)統(tong)(tong)均使(shi)用(yong)許多膠(jiao)(jiao)管(guan)(guan)(guan)。氣(qi)(qi)割操作(zuo)需要較大的(de)(de)(de)氧(yang)氣(qi)(qi)輸出量，因此與氧(yang)氣(qi)(qi)表高(gao)壓(ya)端連接的(de)(de)(de)氣(qi)(qi)瓶（或(huo)氧(yang)氣(qi)(qi)管(guan)(guan)(guan)道）閥門應(ying)全打開，以便保(bao)證提供足夠的(de)(de)(de)流量和(he)(he)穩定的(de)(de)(de)壓(ya)力，防(fang)止低壓(ya)表雖已表示工作(zuo)壓(ya)力，但使(shi)用(yong)時(shi)(shi)壓(ya)力突然(ran)下降(jiang)，此時(shi)(shi)容易發(fa)生回火，并可能(neng)倒燃進入氧(yang)氣(qi)(qi)膠(jiao)(jiao)管(guan)(guan)(guan)而引起(qi)(qi)爆(bao)炸。在保(bao)存、運輸和(he)(he)使(shi)用(yong)膠(jiao)(jiao)管(guan)(guan)(guan)時(shi)(shi)必須(xu)注意維護，保(bao)持膠(jiao)(jiao)管(guan)(guan)(guan)的(de)(de)(de)清潔(jie)和(he)(he)不受(shou)損壞。例(li)如(ru)避免陽光照射，雨雪浸淋、防(fang)止與酸、堿、油(you)類及其他有機溶(rong)劑等影響膠(jiao)(jiao)管(guan)(guan)(guan)質(zhi)量的(de)(de)(de)物(wu)質(zhi)接觸(chu)。存放(fang)溫度為-15～40℃，距離熱源應(ying)不小(xiao)于(yu)1m.如(ru)果由于(yu)保(bao)存和(he)(he)使(shi)用(yong)時(shi)(shi)維護不善，或(huo)膠(jiao)(jiao)管(guan)(guan)(guan)使(shi)用(yong)日久老化脆硬，這些膠(jiao)(jiao)管(guan)(guan)(guan)內(nei)的(de)(de)(de)硫磺質(zhi)被分解(jie)出來，常(chang)常(chang)會因此引起(qi)(qi)回火爆(bao)炸事故。
