膠管近年(nian)來，開始采(cai)用(yong)熱塑性橡膠(jiao)(jiao)，如(ru)熱塑性聚氨酯橡膠(jiao)(jiao)、聚酯橡膠(jiao)(jiao)等。膠(jiao)(jiao)管(guan)(guan)(guan)因易(yi)彎曲(qu)、能(neng)緩沖、重(zhong)量(liang)(liang)輕及安裝使(shi)(shi)(shi)用(yong)方(fang)便等優(you)點，用(yong)途十分(fen)廣(guang)泛，如(ru)農業(ye)上排灌農田、港灣疏浚(jun)中(zhong)(zhong)吸排泥漿，飛機、坦克、汽車及許多(duo)機械裝備(bei)中(zhong)(zhong)的液壓(ya)(ya)系統、氣(qi)(qi)(qi)動系統、燃油系統均(jun)使(shi)(shi)(shi)用(yong)許多(duo)膠(jiao)(jiao)管(guan)(guan)(guan)。氣(qi)(qi)(qi)割操作需要較大的氧(yang)氣(qi)(qi)(qi)輸(shu)出量(liang)(liang)，因此(ci)與氧(yang)氣(qi)(qi)(qi)表高壓(ya)(ya)端連(lian)接的氣(qi)(qi)(qi)瓶（或氧(yang)氣(qi)(qi)(qi)管(guan)(guan)(guan)道）閥門(men)應(ying)全打開，以(yi)便保(bao)證提供足夠的流(liu)量(liang)(liang)和(he)(he)穩定(ding)的壓(ya)(ya)力，防止低壓(ya)(ya)表雖已(yi)表示(shi)工(gong)作壓(ya)(ya)力，但使(shi)(shi)(shi)用(yong)時(shi)(shi)(shi)壓(ya)(ya)力突然下降(jiang)，此(ci)時(shi)(shi)(shi)容易(yi)發生回火，并可能(neng)倒燃進入氧(yang)氣(qi)(qi)(qi)膠(jiao)(jiao)管(guan)(guan)(guan)而引起爆(bao)炸(zha)。在保(bao)存、運(yun)輸(shu)和(he)(he)使(shi)(shi)(shi)用(yong)膠(jiao)(jiao)管(guan)(guan)(guan)時(shi)(shi)(shi)必(bi)須注(zhu)意維護(hu)，保(bao)持(chi)膠(jiao)(jiao)管(guan)(guan)(guan)的清潔和(he)(he)不受損壞。例如(ru)避免陽光照射，雨雪浸淋、防止與酸、堿、油類及其他有機溶劑等影(ying)響(xiang)膠(jiao)(jiao)管(guan)(guan)(guan)質量(liang)(liang)的物質接觸。存放溫度(du)為(wei)-15～40℃，距離熱源應(ying)不小于(yu)1m.如(ru)果由于(yu)保(bao)存和(he)(he)使(shi)(shi)(shi)用(yong)時(shi)(shi)(shi)維護(hu)不善，或膠(jiao)(jiao)管(guan)(guan)(guan)使(shi)(shi)(shi)用(yong)日久老(lao)化(hua)脆硬，這些膠(jiao)(jiao)管(guan)(guan)(guan)內的硫磺質被分(fen)解出來，常(chang)常(chang)會因此(ci)引起回火爆(bao)炸(zha)事(shi)故。
