膠管近年來(lai)，開始采用(yong)(yong)(yong)熱(re)(re)塑性橡(xiang)膠(jiao)，如熱(re)(re)塑性聚(ju)氨酯(zhi)橡(xiang)膠(jiao)、聚(ju)酯(zhi)橡(xiang)膠(jiao)等。膠(jiao)管(guan)(guan)(guan)(guan)因易(yi)(yi)彎曲、能(neng)(neng)緩(huan)沖、重量輕及(ji)安裝使(shi)用(yong)(yong)(yong)方便等優點，用(yong)(yong)(yong)途十分(fen)廣泛(fan)，如農業(ye)上排灌(guan)農田、港(gang)灣疏(shu)浚中吸排泥漿，飛(fei)機(ji)、坦克、汽車及(ji)許多機(ji)械裝備中的(de)(de)液壓(ya)(ya)系統、氣(qi)動系統、燃(ran)油(you)系統均使(shi)用(yong)(yong)(yong)許多膠(jiao)管(guan)(guan)(guan)(guan)。氣(qi)割操作需要較(jiao)大的(de)(de)氧(yang)(yang)氣(qi)輸出量，因此與(yu)氧(yang)(yang)氣(qi)表高壓(ya)(ya)端連接的(de)(de)氣(qi)瓶(ping)（或氧(yang)(yang)氣(qi)管(guan)(guan)(guan)(guan)道(dao)）閥門應全打開，以(yi)便保證提供足夠(gou)的(de)(de)流量和(he)(he)穩(wen)定的(de)(de)壓(ya)(ya)力，防止(zhi)低壓(ya)(ya)表雖已表示工作壓(ya)(ya)力，但使(shi)用(yong)(yong)(yong)時(shi)(shi)壓(ya)(ya)力突然下降，此時(shi)(shi)容易(yi)(yi)發(fa)生(sheng)回火，并可能(neng)(neng)倒燃(ran)進(jin)入氧(yang)(yang)氣(qi)膠(jiao)管(guan)(guan)(guan)(guan)而(er)引(yin)起(qi)(qi)爆炸(zha)(zha)。在(zai)保存(cun)、運輸和(he)(he)使(shi)用(yong)(yong)(yong)膠(jiao)管(guan)(guan)(guan)(guan)時(shi)(shi)必須注意維護，保持膠(jiao)管(guan)(guan)(guan)(guan)的(de)(de)清潔和(he)(he)不受損壞。例如避(bi)免(mian)陽光照射，雨雪浸(jin)淋、防止(zhi)與(yu)酸、堿、油(you)類(lei)及(ji)其他有機(ji)溶劑等影響膠(jiao)管(guan)(guan)(guan)(guan)質量的(de)(de)物質接觸。存(cun)放(fang)溫(wen)度為-15～40℃，距離熱(re)(re)源應不小(xiao)于1m.如果由于保存(cun)和(he)(he)使(shi)用(yong)(yong)(yong)時(shi)(shi)維護不善，或膠(jiao)管(guan)(guan)(guan)(guan)使(shi)用(yong)(yong)(yong)日久老化脆硬(ying)，這些膠(jiao)管(guan)(guan)(guan)(guan)內的(de)(de)硫磺質被(bei)分(fen)解(jie)出來(lai)，常(chang)常(chang)會因此引(yin)起(qi)(qi)回火爆炸(zha)(zha)事(shi)故。
