膠管近年來，開始采用(yong)(yong)熱(re)塑(su)性橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)，如(ru)熱(re)塑(su)性聚氨酯橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)、聚酯橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)等(deng)。膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)因(yin)(yin)易彎曲、能(neng)緩沖、重量輕及(ji)安裝使(shi)用(yong)(yong)方便等(deng)優點，用(yong)(yong)途十分廣泛，如(ru)農業上排灌農田、港灣疏浚中(zhong)(zhong)吸(xi)排泥漿，飛機(ji)(ji)、坦克、汽車及(ji)許(xu)多(duo)機(ji)(ji)械(xie)裝備中(zhong)(zhong)的液壓(ya)系(xi)統(tong)、氣(qi)(qi)動系(xi)統(tong)、燃(ran)油(you)系(xi)統(tong)均使(shi)用(yong)(yong)許(xu)多(duo)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)。氣(qi)(qi)割操作需要較大的氧(yang)氣(qi)(qi)輸出(chu)(chu)量，因(yin)(yin)此(ci)(ci)與(yu)氧(yang)氣(qi)(qi)表高壓(ya)端連接(jie)的氣(qi)(qi)瓶（或(huo)氧(yang)氣(qi)(qi)管(guan)(guan)(guan)道）閥門應全打開，以便保證提(ti)供足夠的流量和(he)穩定的壓(ya)力(li)，防止低壓(ya)表雖(sui)已(yi)表示(shi)工(gong)作壓(ya)力(li)，但使(shi)用(yong)(yong)時(shi)壓(ya)力(li)突然下降，此(ci)(ci)時(shi)容易發生回火(huo)，并(bing)可能(neng)倒燃(ran)進入(ru)氧(yang)氣(qi)(qi)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)而(er)引起(qi)爆炸。在保存(cun)、運輸和(he)使(shi)用(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)時(shi)必須(xu)注意維護，保持(chi)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)的清潔和(he)不受損(sun)壞(huai)。例如(ru)避(bi)免陽(yang)光照射，雨雪浸淋(lin)、防止與(yu)酸、堿、油(you)類及(ji)其他有(you)機(ji)(ji)溶劑等(deng)影響膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)質(zhi)量的物質(zhi)接(jie)觸。存(cun)放(fang)溫度(du)為-15～40℃，距離熱(re)源應不小于(yu)(yu)1m.如(ru)果由于(yu)(yu)保存(cun)和(he)使(shi)用(yong)(yong)時(shi)維護不善，或(huo)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)使(shi)用(yong)(yong)日(ri)久老化脆硬，這些膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)內的硫(liu)磺質(zhi)被分解(jie)出(chu)(chu)來，常(chang)常(chang)會因(yin)(yin)此(ci)(ci)引起(qi)回火(huo)爆炸事故。
