膠管近年來(lai)，開始采用(yong)(yong)(yong)熱(re)塑性橡(xiang)膠(jiao)(jiao)(jiao)，如(ru)(ru)熱(re)塑性聚氨酯橡(xiang)膠(jiao)(jiao)(jiao)、聚酯橡(xiang)膠(jiao)(jiao)(jiao)等(deng)。膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)因(yin)易(yi)(yi)彎曲、能(neng)緩沖、重(zhong)量輕及安裝(zhuang)使(shi)用(yong)(yong)(yong)方便(bian)等(deng)優點(dian)，用(yong)(yong)(yong)途十分(fen)廣(guang)泛，如(ru)(ru)農業上排灌農田、港(gang)灣疏浚中(zhong)吸排泥漿，飛(fei)機(ji)(ji)、坦克、汽車及許多機(ji)(ji)械(xie)裝(zhuang)備中(zhong)的(de)(de)液壓(ya)(ya)(ya)系(xi)統(tong)、氣動系(xi)統(tong)、燃油(you)系(xi)統(tong)均使(shi)用(yong)(yong)(yong)許多膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)。氣割操作(zuo)需要(yao)較大(da)的(de)(de)氧(yang)氣輸出量，因(yin)此與氧(yang)氣表高壓(ya)(ya)(ya)端連接的(de)(de)氣瓶（或氧(yang)氣管(guan)(guan)(guan)道）閥門應全打開，以便(bian)保(bao)證提供足(zu)夠的(de)(de)流量和穩定的(de)(de)壓(ya)(ya)(ya)力，防(fang)(fang)止(zhi)低壓(ya)(ya)(ya)表雖(sui)已表示工作(zuo)壓(ya)(ya)(ya)力，但使(shi)用(yong)(yong)(yong)時壓(ya)(ya)(ya)力突然下降，此時容易(yi)(yi)發生回火，并可能(neng)倒燃進入氧(yang)氣膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)而引起爆炸。在(zai)保(bao)存、運輸和使(shi)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)時必須注意(yi)維(wei)護，保(bao)持膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)的(de)(de)清潔和不(bu)受(shou)損壞。例如(ru)(ru)避免陽(yang)光照射，雨雪浸淋、防(fang)(fang)止(zhi)與酸、堿、油(you)類及其他有機(ji)(ji)溶(rong)劑等(deng)影響膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)質量的(de)(de)物質接觸。存放溫度為-15～40℃，距離熱(re)源(yuan)應不(bu)小于1m.如(ru)(ru)果由于保(bao)存和使(shi)用(yong)(yong)(yong)時維(wei)護不(bu)善(shan)，或膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)使(shi)用(yong)(yong)(yong)日(ri)久老化脆硬，這些膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)內的(de)(de)硫磺質被分(fen)解出來(lai)，常常會(hui)因(yin)此引起回火爆炸事故。
