膠管近年來，開始采用(yong)(yong)熱塑(su)性(xing)橡(xiang)(xiang)膠(jiao)，如熱塑(su)性(xing)聚氨酯橡(xiang)(xiang)膠(jiao)、聚酯橡(xiang)(xiang)膠(jiao)等(deng)。膠(jiao)管(guan)(guan)(guan)(guan)因易彎曲、能緩沖、重量(liang)輕及(ji)安裝使(shi)(shi)用(yong)(yong)方便(bian)等(deng)優點，用(yong)(yong)途(tu)十(shi)分(fen)廣泛，如農業上排灌農田、港灣疏(shu)浚中吸(xi)排泥(ni)漿，飛機(ji)、坦(tan)克、汽(qi)車及(ji)許多機(ji)械裝備中的液壓(ya)(ya)系統(tong)、氣(qi)動系統(tong)、燃(ran)油系統(tong)均使(shi)(shi)用(yong)(yong)許多膠(jiao)管(guan)(guan)(guan)(guan)。氣(qi)割操作需要較大的氧氣(qi)輸出量(liang)，因此與(yu)氧氣(qi)表(biao)(biao)高壓(ya)(ya)端(duan)連接的氣(qi)瓶（或氧氣(qi)管(guan)(guan)(guan)(guan)道）閥門應(ying)全打開，以便(bian)保(bao)證提供足夠的流量(liang)和(he)穩定的壓(ya)(ya)力(li)(li)，防止低壓(ya)(ya)表(biao)(biao)雖已表(biao)(biao)示(shi)工作壓(ya)(ya)力(li)(li)，但使(shi)(shi)用(yong)(yong)時(shi)壓(ya)(ya)力(li)(li)突然下降，此時(shi)容易發生回火，并(bing)可能倒(dao)燃(ran)進入氧氣(qi)膠(jiao)管(guan)(guan)(guan)(guan)而引起(qi)爆炸。在保(bao)存、運輸和(he)使(shi)(shi)用(yong)(yong)膠(jiao)管(guan)(guan)(guan)(guan)時(shi)必須注意(yi)維護(hu)(hu)，保(bao)持膠(jiao)管(guan)(guan)(guan)(guan)的清潔和(he)不(bu)受(shou)損壞。例如避免陽(yang)光照(zhao)射(she)，雨(yu)雪浸淋、防止與(yu)酸、堿(jian)、油類(lei)及(ji)其他有機(ji)溶劑等(deng)影響膠(jiao)管(guan)(guan)(guan)(guan)質(zhi)量(liang)的物(wu)質(zhi)接觸。存放(fang)溫度為-15～40℃，距離(li)熱源應(ying)不(bu)小于1m.如果由于保(bao)存和(he)使(shi)(shi)用(yong)(yong)時(shi)維護(hu)(hu)不(bu)善，或膠(jiao)管(guan)(guan)(guan)(guan)使(shi)(shi)用(yong)(yong)日久老化脆硬，這些膠(jiao)管(guan)(guan)(guan)(guan)內(nei)的硫磺質(zhi)被分(fen)解出來，常常會因此引起(qi)回火爆炸事故。
