膠管近(jin)年來，開始采用(yong)(yong)(yong)(yong)熱塑性橡(xiang)膠，如(ru)熱塑性聚(ju)氨酯(zhi)橡(xiang)膠、聚(ju)酯(zhi)橡(xiang)膠等。膠管(guan)(guan)因易(yi)彎曲、能緩沖、重量(liang)輕及安裝使(shi)用(yong)(yong)(yong)(yong)方便等優點(dian)，用(yong)(yong)(yong)(yong)途十分(fen)廣泛，如(ru)農業上排灌農田、港(gang)灣疏浚中(zhong)吸排泥(ni)漿，飛機(ji)(ji)、坦克、汽(qi)車及許多機(ji)(ji)械裝備中(zhong)的液壓(ya)系統、氣(qi)(qi)動系統、燃(ran)油系統均使(shi)用(yong)(yong)(yong)(yong)許多膠管(guan)(guan)。氣(qi)(qi)割操作需要較大的氧(yang)氣(qi)(qi)輸出量(liang)，因此(ci)(ci)與(yu)氧(yang)氣(qi)(qi)表高壓(ya)端連接(jie)的氣(qi)(qi)瓶（或(huo)(huo)氧(yang)氣(qi)(qi)管(guan)(guan)道）閥門應(ying)全打開，以便保(bao)(bao)證提供足夠(gou)的流量(liang)和穩(wen)定的壓(ya)力，防止低(di)壓(ya)表雖已表示工作壓(ya)力，但使(shi)用(yong)(yong)(yong)(yong)時壓(ya)力突然下降，此(ci)(ci)時容(rong)易(yi)發生回火，并可能倒燃(ran)進入氧(yang)氣(qi)(qi)膠管(guan)(guan)而引起爆炸。在保(bao)(bao)存、運輸和使(shi)用(yong)(yong)(yong)(yong)膠管(guan)(guan)時必須注(zhu)意維(wei)護，保(bao)(bao)持(chi)膠管(guan)(guan)的清潔和不受(shou)損(sun)壞。例如(ru)避免陽光照射(she)，雨雪浸淋、防止與(yu)酸、堿、油類(lei)及其(qi)他有機(ji)(ji)溶劑等影響膠管(guan)(guan)質量(liang)的物質接(jie)觸。存放溫度為-15～40℃，距(ju)離熱源應(ying)不小(xiao)于1m.如(ru)果由于保(bao)(bao)存和使(shi)用(yong)(yong)(yong)(yong)時維(wei)護不善，或(huo)(huo)膠管(guan)(guan)使(shi)用(yong)(yong)(yong)(yong)日久老化脆硬，這些膠管(guan)(guan)內的硫磺質被(bei)分(fen)解出來，常(chang)常(chang)會因此(ci)(ci)引起回火爆炸事故。
