膠管近年來(lai)(lai)，開(kai)始采用(yong)(yong)(yong)(yong)熱(re)塑性(xing)橡膠(jiao)(jiao)，如熱(re)塑性(xing)聚(ju)氨酯橡膠(jiao)(jiao)、聚(ju)酯橡膠(jiao)(jiao)等(deng)。膠(jiao)(jiao)管(guan)(guan)(guan)(guan)因易(yi)彎(wan)曲、能(neng)緩沖、重量(liang)輕及(ji)安(an)裝使(shi)(shi)用(yong)(yong)(yong)(yong)方便等(deng)優點，用(yong)(yong)(yong)(yong)途十分(fen)廣泛，如農(nong)業上排(pai)灌農(nong)田(tian)、港灣疏浚中(zhong)吸排(pai)泥漿，飛機、坦克、汽車(che)及(ji)許多(duo)機械裝備中(zhong)的(de)(de)(de)(de)液壓(ya)系統、氣(qi)動系統、燃油(you)系統均(jun)使(shi)(shi)用(yong)(yong)(yong)(yong)許多(duo)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)。氣(qi)割操作(zuo)需要較大的(de)(de)(de)(de)氧(yang)氣(qi)輸出(chu)量(liang)，因此與(yu)氧(yang)氣(qi)表(biao)高壓(ya)端連接的(de)(de)(de)(de)氣(qi)瓶(ping)（或(huo)氧(yang)氣(qi)管(guan)(guan)(guan)(guan)道）閥門應全打開(kai)，以便保(bao)(bao)(bao)證提供足夠的(de)(de)(de)(de)流量(liang)和(he)穩定的(de)(de)(de)(de)壓(ya)力，防(fang)止(zhi)低壓(ya)表(biao)雖已表(biao)示工作(zuo)壓(ya)力，但使(shi)(shi)用(yong)(yong)(yong)(yong)時(shi)(shi)壓(ya)力突然下降，此時(shi)(shi)容易(yi)發生回火，并可能(neng)倒燃進(jin)入氧(yang)氣(qi)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)而引(yin)起爆炸。在保(bao)(bao)(bao)存、運輸和(he)使(shi)(shi)用(yong)(yong)(yong)(yong)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)時(shi)(shi)必須注意(yi)維護，保(bao)(bao)(bao)持膠(jiao)(jiao)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)清(qing)潔和(he)不(bu)受(shou)損壞。例如避免陽光(guang)照射(she)，雨(yu)雪(xue)浸淋、防(fang)止(zhi)與(yu)酸(suan)、堿、油(you)類及(ji)其他有機溶劑等(deng)影(ying)響膠(jiao)(jiao)管(guan)(guan)(guan)(guan)質(zhi)量(liang)的(de)(de)(de)(de)物質(zhi)接觸。存放溫度(du)為-15～40℃，距離(li)熱(re)源應不(bu)小于1m.如果由于保(bao)(bao)(bao)存和(he)使(shi)(shi)用(yong)(yong)(yong)(yong)時(shi)(shi)維護不(bu)善，或(huo)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)使(shi)(shi)用(yong)(yong)(yong)(yong)日久(jiu)老化脆硬，這些膠(jiao)(jiao)管(guan)(guan)(guan)(guan)內的(de)(de)(de)(de)硫磺質(zhi)被分(fen)解出(chu)來(lai)(lai)，常常會因此引(yin)起回火爆炸事故(gu)。
