膠管近(jin)年來(lai)，開始采(cai)用(yong)(yong)熱塑性(xing)橡膠(jiao)(jiao)，如(ru)熱塑性(xing)聚(ju)氨酯(zhi)橡膠(jiao)(jiao)、聚(ju)酯(zhi)橡膠(jiao)(jiao)等。膠(jiao)(jiao)管(guan)(guan)因易彎曲、能(neng)緩沖、重量輕及(ji)安裝使(shi)用(yong)(yong)方便(bian)等優點，用(yong)(yong)途十分(fen)廣泛(fan)，如(ru)農(nong)業上排灌(guan)農(nong)田、港灣疏浚(jun)中(zhong)(zhong)吸排泥漿，飛機、坦克、汽車及(ji)許多機械裝備中(zhong)(zhong)的(de)(de)(de)液(ye)壓(ya)(ya)系統(tong)、氣(qi)(qi)(qi)(qi)動系統(tong)、燃油系統(tong)均使(shi)用(yong)(yong)許多膠(jiao)(jiao)管(guan)(guan)。氣(qi)(qi)(qi)(qi)割(ge)操作(zuo)需要較大(da)的(de)(de)(de)氧(yang)氣(qi)(qi)(qi)(qi)輸出(chu)量，因此與氧(yang)氣(qi)(qi)(qi)(qi)表(biao)高壓(ya)(ya)端連(lian)接(jie)的(de)(de)(de)氣(qi)(qi)(qi)(qi)瓶（或氧(yang)氣(qi)(qi)(qi)(qi)管(guan)(guan)道）閥門(men)應(ying)全(quan)打(da)開，以便(bian)保(bao)證提(ti)供足(zu)夠的(de)(de)(de)流(liu)量和穩定(ding)的(de)(de)(de)壓(ya)(ya)力，防止(zhi)低壓(ya)(ya)表(biao)雖已表(biao)示工作(zuo)壓(ya)(ya)力，但使(shi)用(yong)(yong)時(shi)壓(ya)(ya)力突然下降，此時(shi)容易發生(sheng)回(hui)火(huo)，并可能(neng)倒燃進入氧(yang)氣(qi)(qi)(qi)(qi)膠(jiao)(jiao)管(guan)(guan)而引起爆炸。在保(bao)存(cun)、運輸和使(shi)用(yong)(yong)膠(jiao)(jiao)管(guan)(guan)時(shi)必須(xu)注意維護(hu)，保(bao)持(chi)膠(jiao)(jiao)管(guan)(guan)的(de)(de)(de)清潔(jie)和不受損壞。例如(ru)避免陽光照射，雨雪浸淋、防止(zhi)與酸、堿、油類及(ji)其(qi)他有機溶(rong)劑(ji)等影(ying)響(xiang)膠(jiao)(jiao)管(guan)(guan)質量的(de)(de)(de)物質接(jie)觸。存(cun)放溫度(du)為-15～40℃，距(ju)離熱源應(ying)不小于(yu)1m.如(ru)果由于(yu)保(bao)存(cun)和使(shi)用(yong)(yong)時(shi)維護(hu)不善，或膠(jiao)(jiao)管(guan)(guan)使(shi)用(yong)(yong)日久老化(hua)脆(cui)硬，這些膠(jiao)(jiao)管(guan)(guan)內(nei)的(de)(de)(de)硫磺(huang)質被分(fen)解出(chu)來(lai)，常常會因此引起回(hui)火(huo)爆炸事故。
