膠管近年(nian)來(lai)，開始采用(yong)(yong)(yong)(yong)熱(re)塑性橡膠(jiao)(jiao)，如熱(re)塑性聚氨酯橡膠(jiao)(jiao)、聚酯橡膠(jiao)(jiao)等(deng)。膠(jiao)(jiao)管(guan)(guan)因(yin)易彎曲、能緩沖、重量(liang)輕及安裝(zhuang)使(shi)用(yong)(yong)(yong)(yong)方(fang)便等(deng)優點，用(yong)(yong)(yong)(yong)途十分(fen)廣泛，如農(nong)(nong)業上排灌(guan)農(nong)(nong)田、港灣疏(shu)浚中吸排泥漿(jiang)，飛機、坦克、汽車及許(xu)(xu)多(duo)(duo)機械裝(zhuang)備中的(de)液(ye)壓(ya)系統(tong)(tong)、氣(qi)動系統(tong)(tong)、燃(ran)油(you)系統(tong)(tong)均使(shi)用(yong)(yong)(yong)(yong)許(xu)(xu)多(duo)(duo)膠(jiao)(jiao)管(guan)(guan)。氣(qi)割(ge)操(cao)作(zuo)需要(yao)較大的(de)氧(yang)氣(qi)輸出量(liang)，因(yin)此與氧(yang)氣(qi)表高(gao)壓(ya)端連接的(de)氣(qi)瓶（或氧(yang)氣(qi)管(guan)(guan)道）閥門應全(quan)打開，以便保(bao)證(zheng)提供足夠的(de)流(liu)量(liang)和(he)穩(wen)定的(de)壓(ya)力(li)，防止低壓(ya)表雖已表示工(gong)作(zuo)壓(ya)力(li)，但(dan)使(shi)用(yong)(yong)(yong)(yong)時壓(ya)力(li)突然下降(jiang)，此時容易發(fa)生回火(huo)，并(bing)可能倒(dao)燃(ran)進(jin)入氧(yang)氣(qi)膠(jiao)(jiao)管(guan)(guan)而引(yin)起(qi)爆炸(zha)。在(zai)保(bao)存(cun)、運輸和(he)使(shi)用(yong)(yong)(yong)(yong)膠(jiao)(jiao)管(guan)(guan)時必須(xu)注意(yi)維(wei)護，保(bao)持(chi)膠(jiao)(jiao)管(guan)(guan)的(de)清潔(jie)和(he)不(bu)(bu)受損壞。例如避免(mian)陽(yang)光照射，雨(yu)雪浸淋(lin)、防止與酸(suan)、堿(jian)、油(you)類(lei)及其他(ta)有(you)機溶(rong)劑等(deng)影響膠(jiao)(jiao)管(guan)(guan)質(zhi)量(liang)的(de)物質(zhi)接觸。存(cun)放溫度為-15～40℃，距離(li)熱(re)源(yuan)應不(bu)(bu)小于(yu)1m.如果由(you)于(yu)保(bao)存(cun)和(he)使(shi)用(yong)(yong)(yong)(yong)時維(wei)護不(bu)(bu)善，或膠(jiao)(jiao)管(guan)(guan)使(shi)用(yong)(yong)(yong)(yong)日久(jiu)老化脆硬，這些(xie)膠(jiao)(jiao)管(guan)(guan)內的(de)硫磺質(zhi)被分(fen)解出來(lai)，常(chang)常(chang)會因(yin)此引(yin)起(qi)回火(huo)爆炸(zha)事故。
