膠管近年(nian)來(lai)，開(kai)始采用(yong)熱(re)(re)塑(su)(su)性橡膠(jiao)，如熱(re)(re)塑(su)(su)性聚氨酯橡膠(jiao)、聚酯橡膠(jiao)等。膠(jiao)管(guan)(guan)因易彎曲、能(neng)緩沖(chong)、重量輕及(ji)安裝使(shi)用(yong)方便(bian)(bian)等優點(dian)，用(yong)途十分(fen)廣泛，如農業(ye)上(shang)排灌農田(tian)、港(gang)灣疏浚中(zhong)(zhong)吸排泥(ni)漿(jiang)，飛機(ji)(ji)、坦克、汽車(che)及(ji)許(xu)多(duo)機(ji)(ji)械裝備中(zhong)(zhong)的液壓(ya)(ya)系(xi)統(tong)、氣(qi)(qi)(qi)(qi)(qi)動系(xi)統(tong)、燃油系(xi)統(tong)均(jun)使(shi)用(yong)許(xu)多(duo)膠(jiao)管(guan)(guan)。氣(qi)(qi)(qi)(qi)(qi)割操(cao)作需要較(jiao)大(da)的氧氣(qi)(qi)(qi)(qi)(qi)輸(shu)出(chu)量，因此與(yu)氧氣(qi)(qi)(qi)(qi)(qi)表高壓(ya)(ya)端連接的氣(qi)(qi)(qi)(qi)(qi)瓶（或(huo)氧氣(qi)(qi)(qi)(qi)(qi)管(guan)(guan)道）閥門應全打開(kai)，以便(bian)(bian)保(bao)證提供(gong)足夠(gou)的流(liu)量和(he)穩定的壓(ya)(ya)力，防止低壓(ya)(ya)表雖(sui)已表示工作壓(ya)(ya)力，但使(shi)用(yong)時(shi)(shi)壓(ya)(ya)力突然下降，此時(shi)(shi)容易發(fa)生(sheng)回火，并(bing)可(ke)能(neng)倒燃進入氧氣(qi)(qi)(qi)(qi)(qi)膠(jiao)管(guan)(guan)而引起(qi)爆炸。在(zai)保(bao)存(cun)、運輸(shu)和(he)使(shi)用(yong)膠(jiao)管(guan)(guan)時(shi)(shi)必須注意維護(hu)，保(bao)持膠(jiao)管(guan)(guan)的清潔和(he)不受損壞。例(li)如避免陽光(guang)照射，雨雪浸(jin)淋、防止與(yu)酸、堿(jian)、油類及(ji)其他有機(ji)(ji)溶劑等影響膠(jiao)管(guan)(guan)質(zhi)量的物(wu)質(zhi)接觸。存(cun)放(fang)溫度為-15～40℃，距離熱(re)(re)源應不小(xiao)于1m.如果由于保(bao)存(cun)和(he)使(shi)用(yong)時(shi)(shi)維護(hu)不善，或(huo)膠(jiao)管(guan)(guan)使(shi)用(yong)日久老化脆硬(ying)，這(zhe)些(xie)膠(jiao)管(guan)(guan)內的硫磺質(zhi)被分(fen)解出(chu)來(lai)，常常會因此引起(qi)回火爆炸事故。
