膠管近年來，開(kai)始采用(yong)(yong)(yong)(yong)熱塑性橡(xiang)膠(jiao)，如熱塑性聚(ju)氨酯橡(xiang)膠(jiao)、聚(ju)酯橡(xiang)膠(jiao)等(deng)(deng)。膠(jiao)管(guan)(guan)(guan)因(yin)易彎曲、能緩沖、重量(liang)(liang)輕及(ji)安裝使(shi)用(yong)(yong)(yong)(yong)方(fang)便(bian)等(deng)(deng)優(you)點，用(yong)(yong)(yong)(yong)途十分廣泛，如農業(ye)上排灌農田、港灣疏浚(jun)中吸排泥漿(jiang)，飛(fei)機、坦(tan)克、汽車及(ji)許多(duo)機械裝備中的(de)(de)(de)液壓(ya)系(xi)(xi)統、氣(qi)動系(xi)(xi)統、燃油系(xi)(xi)統均使(shi)用(yong)(yong)(yong)(yong)許多(duo)膠(jiao)管(guan)(guan)(guan)。氣(qi)割操作需要較大(da)的(de)(de)(de)氧(yang)(yang)(yang)氣(qi)輸(shu)出(chu)量(liang)(liang)，因(yin)此(ci)與氧(yang)(yang)(yang)氣(qi)表(biao)高壓(ya)端連接(jie)的(de)(de)(de)氣(qi)瓶（或氧(yang)(yang)(yang)氣(qi)管(guan)(guan)(guan)道）閥門應全打開(kai)，以便(bian)保證提(ti)供足夠的(de)(de)(de)流量(liang)(liang)和(he)(he)穩(wen)定的(de)(de)(de)壓(ya)力(li)，防(fang)止低(di)壓(ya)表(biao)雖已表(biao)示(shi)工作壓(ya)力(li)，但使(shi)用(yong)(yong)(yong)(yong)時壓(ya)力(li)突然(ran)下降，此(ci)時容易發生回(hui)火(huo)，并可(ke)能倒燃進入氧(yang)(yang)(yang)氣(qi)膠(jiao)管(guan)(guan)(guan)而引起爆(bao)炸。在保存、運輸(shu)和(he)(he)使(shi)用(yong)(yong)(yong)(yong)膠(jiao)管(guan)(guan)(guan)時必須注意維(wei)護，保持膠(jiao)管(guan)(guan)(guan)的(de)(de)(de)清潔(jie)和(he)(he)不受損壞。例(li)如避免陽光照射，雨(yu)雪浸淋(lin)、防(fang)止與酸(suan)、堿、油類及(ji)其他有機溶劑等(deng)(deng)影響膠(jiao)管(guan)(guan)(guan)質(zhi)(zhi)量(liang)(liang)的(de)(de)(de)物質(zhi)(zhi)接(jie)觸。存放溫度為-15～40℃，距離熱源應不小于(yu)1m.如果(guo)由于(yu)保存和(he)(he)使(shi)用(yong)(yong)(yong)(yong)時維(wei)護不善(shan)，或膠(jiao)管(guan)(guan)(guan)使(shi)用(yong)(yong)(yong)(yong)日久老(lao)化(hua)脆(cui)硬，這些膠(jiao)管(guan)(guan)(guan)內的(de)(de)(de)硫磺質(zhi)(zhi)被(bei)分解(jie)出(chu)來，常(chang)常(chang)會因(yin)此(ci)引起回(hui)火(huo)爆(bao)炸事故。
