膠管近年來，開始采(cai)用(yong)(yong)(yong)熱塑性橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，如熱塑性聚氨酯橡(xiang)膠(jiao)(jiao)(jiao)(jiao)、聚酯橡(xiang)膠(jiao)(jiao)(jiao)(jiao)等。膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)因(yin)易彎曲、能緩沖(chong)、重量輕及(ji)安裝使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)方便(bian)等優(you)點，用(yong)(yong)(yong)途十分(fen)廣(guang)泛，如農(nong)業(ye)上排灌農(nong)田、港灣疏浚(jun)中吸排泥漿，飛機(ji)、坦克、汽車及(ji)許多機(ji)械(xie)裝備(bei)中的(de)(de)(de)液壓(ya)(ya)系(xi)統(tong)、氣(qi)動系(xi)統(tong)、燃油系(xi)統(tong)均使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)許多膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)。氣(qi)割操作(zuo)(zuo)需要較大的(de)(de)(de)氧氣(qi)輸(shu)出量，因(yin)此與(yu)(yu)氧氣(qi)表(biao)高(gao)壓(ya)(ya)端連接的(de)(de)(de)氣(qi)瓶（或氧氣(qi)管(guan)(guan)道(dao)）閥門(men)應全(quan)打開，以便(bian)保(bao)證提供(gong)足夠的(de)(de)(de)流量和(he)穩定的(de)(de)(de)壓(ya)(ya)力，防止(zhi)(zhi)低壓(ya)(ya)表(biao)雖(sui)已表(biao)示工作(zuo)(zuo)壓(ya)(ya)力，但使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)時壓(ya)(ya)力突然(ran)下(xia)降，此時容易發生回火(huo)，并可能倒(dao)燃進入氧氣(qi)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)而引起爆炸(zha)。在保(bao)存(cun)、運(yun)輸(shu)和(he)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)時必(bi)須注意維護，保(bao)持膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)的(de)(de)(de)清(qing)潔和(he)不受損壞。例如避免陽光照射(she)，雨(yu)雪(xue)浸淋、防止(zhi)(zhi)與(yu)(yu)酸(suan)、堿、油類及(ji)其他有機(ji)溶劑等影響膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)質量的(de)(de)(de)物質接觸。存(cun)放溫(wen)度(du)為-15～40℃，距(ju)離熱源應不小于(yu)1m.如果由于(yu)保(bao)存(cun)和(he)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)時維護不善(shan)，或膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)日久(jiu)老(lao)化脆硬，這些(xie)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)內的(de)(de)(de)硫磺質被(bei)分(fen)解出來，常常會因(yin)此引起回火(huo)爆炸(zha)事故。
