膠管近年來(lai)，開(kai)始采用(yong)(yong)(yong)熱塑性(xing)橡膠(jiao)(jiao)(jiao)，如熱塑性(xing)聚(ju)氨酯橡膠(jiao)(jiao)(jiao)、聚(ju)酯橡膠(jiao)(jiao)(jiao)等。膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)因易(yi)彎曲、能緩沖、重量(liang)輕及安裝使(shi)用(yong)(yong)(yong)方便等優(you)點，用(yong)(yong)(yong)途十分廣泛(fan)，如農(nong)業上排灌(guan)農(nong)田、港灣疏浚中(zhong)吸排泥漿，飛機(ji)、坦克、汽(qi)車及許(xu)多機(ji)械裝備(bei)中(zhong)的(de)(de)(de)(de)液壓(ya)(ya)(ya)系統(tong)、氣動(dong)系統(tong)、燃油系統(tong)均使(shi)用(yong)(yong)(yong)許(xu)多膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)。氣割(ge)操(cao)作需要較大(da)的(de)(de)(de)(de)氧氣輸(shu)出量(liang)，因此與(yu)氧氣表(biao)高壓(ya)(ya)(ya)端連接的(de)(de)(de)(de)氣瓶（或氧氣管(guan)(guan)(guan)(guan)道）閥門應全打開(kai)，以便保證提供足夠的(de)(de)(de)(de)流量(liang)和穩(wen)定的(de)(de)(de)(de)壓(ya)(ya)(ya)力，防止低壓(ya)(ya)(ya)表(biao)雖(sui)已表(biao)示(shi)工作壓(ya)(ya)(ya)力，但使(shi)用(yong)(yong)(yong)時(shi)壓(ya)(ya)(ya)力突然下降，此時(shi)容易(yi)發生回火，并可能倒燃進入氧氣膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)而引起(qi)爆(bao)炸。在保存(cun)、運輸(shu)和使(shi)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)時(shi)必須(xu)注意維護，保持膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)清潔和不受損(sun)壞。例如避免陽光照射(she)，雨雪浸淋(lin)、防止與(yu)酸(suan)、堿(jian)、油類及其他有機(ji)溶劑等影(ying)響(xiang)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)質量(liang)的(de)(de)(de)(de)物質接觸。存(cun)放溫度為-15～40℃，距離熱源應不小于1m.如果由于保存(cun)和使(shi)用(yong)(yong)(yong)時(shi)維護不善(shan)，或膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)使(shi)用(yong)(yong)(yong)日久老化脆硬，這些(xie)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)內的(de)(de)(de)(de)硫磺質被分解出來(lai)，常(chang)常(chang)會因此引起(qi)回火爆(bao)炸事(shi)故(gu)。
