膠管近年來(lai)，開(kai)始(shi)采用(yong)(yong)(yong)熱塑性橡(xiang)(xiang)膠(jiao)(jiao)，如熱塑性聚氨酯橡(xiang)(xiang)膠(jiao)(jiao)、聚酯橡(xiang)(xiang)膠(jiao)(jiao)等。膠(jiao)(jiao)管(guan)(guan)(guan)(guan)因易(yi)彎曲、能緩沖(chong)、重量輕及安裝使(shi)用(yong)(yong)(yong)方便等優點，用(yong)(yong)(yong)途(tu)十分廣泛，如農業上排灌農田、港灣疏浚中吸(xi)排泥漿，飛機(ji)、坦克、汽車及許多機(ji)械裝備中的(de)液壓(ya)系(xi)統(tong)、氣(qi)(qi)動(dong)系(xi)統(tong)、燃油(you)系(xi)統(tong)均使(shi)用(yong)(yong)(yong)許多膠(jiao)(jiao)管(guan)(guan)(guan)(guan)。氣(qi)(qi)割(ge)操(cao)作(zuo)(zuo)需要較大的(de)氧氣(qi)(qi)輸(shu)出量，因此(ci)與氧氣(qi)(qi)表(biao)高壓(ya)端(duan)連接的(de)氣(qi)(qi)瓶（或氧氣(qi)(qi)管(guan)(guan)(guan)(guan)道）閥門應全(quan)打(da)開(kai)，以(yi)便保(bao)證提供足夠的(de)流(liu)量和(he)穩定的(de)壓(ya)力，防(fang)止(zhi)低壓(ya)表(biao)雖(sui)已表(biao)示工作(zuo)(zuo)壓(ya)力，但使(shi)用(yong)(yong)(yong)時(shi)(shi)壓(ya)力突然下(xia)降(jiang)，此(ci)時(shi)(shi)容易(yi)發生回火，并可能倒(dao)燃進入氧氣(qi)(qi)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)而引(yin)起爆(bao)炸(zha)。在保(bao)存、運輸(shu)和(he)使(shi)用(yong)(yong)(yong)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)時(shi)(shi)必(bi)須注意維護，保(bao)持(chi)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)的(de)清(qing)潔和(he)不(bu)(bu)受(shou)損壞。例(li)如避免陽光照(zhao)射(she)，雨雪浸(jin)淋、防(fang)止(zhi)與酸、堿、油(you)類及其他有機(ji)溶劑(ji)等影響(xiang)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)質量的(de)物(wu)質接觸(chu)。存放溫度為(wei)-15～40℃，距離熱源應不(bu)(bu)小(xiao)于1m.如果(guo)由于保(bao)存和(he)使(shi)用(yong)(yong)(yong)時(shi)(shi)維護不(bu)(bu)善，或膠(jiao)(jiao)管(guan)(guan)(guan)(guan)使(shi)用(yong)(yong)(yong)日久老(lao)化脆硬，這些膠(jiao)(jiao)管(guan)(guan)(guan)(guan)內的(de)硫磺(huang)質被分解出來(lai)，常常會(hui)因此(ci)引(yin)起回火爆(bao)炸(zha)事故。
