膠管近年來(lai)，開始采(cai)用(yong)(yong)熱塑性橡(xiang)膠(jiao)，如(ru)熱塑性聚(ju)氨酯(zhi)橡(xiang)膠(jiao)、聚(ju)酯(zhi)橡(xiang)膠(jiao)等(deng)。膠(jiao)管(guan)(guan)因易彎曲、能緩沖、重量(liang)(liang)輕及(ji)安裝使(shi)(shi)(shi)用(yong)(yong)方便(bian)等(deng)優點，用(yong)(yong)途十分(fen)(fen)廣泛，如(ru)農業上(shang)排灌農田、港灣疏浚中(zhong)吸排泥漿(jiang)，飛機、坦克(ke)、汽車及(ji)許(xu)多機械裝備中(zhong)的液(ye)壓系(xi)統(tong)、氣(qi)(qi)(qi)(qi)動(dong)系(xi)統(tong)、燃油系(xi)統(tong)均使(shi)(shi)(shi)用(yong)(yong)許(xu)多膠(jiao)管(guan)(guan)。氣(qi)(qi)(qi)(qi)割(ge)操作需要較大的氧(yang)氣(qi)(qi)(qi)(qi)輸出(chu)量(liang)(liang)，因此(ci)與氧(yang)氣(qi)(qi)(qi)(qi)表(biao)高壓端(duan)連(lian)接(jie)的氣(qi)(qi)(qi)(qi)瓶(ping)（或(huo)氧(yang)氣(qi)(qi)(qi)(qi)管(guan)(guan)道）閥門應全打開，以(yi)便(bian)保(bao)證提供足夠(gou)的流量(liang)(liang)和(he)(he)穩定的壓力，防止(zhi)低壓表(biao)雖(sui)已表(biao)示工作壓力，但使(shi)(shi)(shi)用(yong)(yong)時(shi)(shi)壓力突然下降，此(ci)時(shi)(shi)容易發生(sheng)回火(huo)，并(bing)可能倒燃進入(ru)氧(yang)氣(qi)(qi)(qi)(qi)膠(jiao)管(guan)(guan)而引起爆炸(zha)。在(zai)保(bao)存(cun)(cun)、運輸和(he)(he)使(shi)(shi)(shi)用(yong)(yong)膠(jiao)管(guan)(guan)時(shi)(shi)必須注意維(wei)護(hu)，保(bao)持(chi)膠(jiao)管(guan)(guan)的清潔(jie)和(he)(he)不受損壞。例(li)如(ru)避免陽光照射，雨雪浸(jin)淋(lin)、防止(zhi)與酸、堿(jian)、油類及(ji)其(qi)他有機溶劑(ji)等(deng)影響膠(jiao)管(guan)(guan)質(zhi)量(liang)(liang)的物質(zhi)接(jie)觸。存(cun)(cun)放溫度為(wei)-15～40℃，距(ju)離熱源(yuan)應不小(xiao)于(yu)(yu)1m.如(ru)果由于(yu)(yu)保(bao)存(cun)(cun)和(he)(he)使(shi)(shi)(shi)用(yong)(yong)時(shi)(shi)維(wei)護(hu)不善，或(huo)膠(jiao)管(guan)(guan)使(shi)(shi)(shi)用(yong)(yong)日久老化脆硬(ying)，這些膠(jiao)管(guan)(guan)內(nei)的硫磺(huang)質(zhi)被(bei)分(fen)(fen)解出(chu)來(lai)，常常會(hui)因此(ci)引起回火(huo)爆炸(zha)事故。
