膠管近年(nian)來，開(kai)始采用(yong)(yong)(yong)(yong)熱(re)塑性橡膠(jiao)(jiao)(jiao)(jiao)(jiao)，如熱(re)塑性聚氨(an)酯(zhi)橡膠(jiao)(jiao)(jiao)(jiao)(jiao)、聚酯(zhi)橡膠(jiao)(jiao)(jiao)(jiao)(jiao)等。膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)因(yin)易(yi)彎曲、能緩沖、重(zhong)量輕及安(an)裝(zhuang)使(shi)用(yong)(yong)(yong)(yong)方便(bian)等優點，用(yong)(yong)(yong)(yong)途十分廣泛，如農業上排(pai)(pai)灌(guan)農田(tian)、港灣(wan)疏浚中(zhong)吸排(pai)(pai)泥漿，飛機、坦克、汽車及許多機械(xie)裝(zhuang)備(bei)中(zhong)的(de)(de)液壓系統、氣(qi)動(dong)系統、燃(ran)油系統均使(shi)用(yong)(yong)(yong)(yong)許多膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)。氣(qi)割(ge)操作(zuo)需要較大(da)的(de)(de)氧(yang)氣(qi)輸出量，因(yin)此與氧(yang)氣(qi)表高壓端連接的(de)(de)氣(qi)瓶(ping)（或氧(yang)氣(qi)管(guan)道）閥門應全打開(kai)，以便(bian)保證提供足夠的(de)(de)流量和(he)(he)穩(wen)定的(de)(de)壓力(li)(li)，防(fang)止低(di)壓表雖(sui)已表示工作(zuo)壓力(li)(li)，但使(shi)用(yong)(yong)(yong)(yong)時(shi)壓力(li)(li)突然下降，此時(shi)容易(yi)發(fa)生回火(huo)，并可能倒燃(ran)進入氧(yang)氣(qi)膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)而(er)引起爆(bao)炸。在保存、運輸和(he)(he)使(shi)用(yong)(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)時(shi)必須注意(yi)維護，保持膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)的(de)(de)清(qing)潔和(he)(he)不受損壞(huai)。例如避免陽光照射，雨雪浸淋、防(fang)止與酸(suan)、堿、油類及其他有機溶劑等影響(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)質量的(de)(de)物質接觸(chu)。存放溫度為-15～40℃，距離熱(re)源應不小于(yu)1m.如果由于(yu)保存和(he)(he)使(shi)用(yong)(yong)(yong)(yong)時(shi)維護不善，或膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)使(shi)用(yong)(yong)(yong)(yong)日久老(lao)化脆(cui)硬，這些膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)內的(de)(de)硫(liu)磺質被分解出來，常(chang)常(chang)會因(yin)此引起回火(huo)爆(bao)炸事故(gu)。
