膠管近年來(lai)，開始采(cai)用(yong)(yong)(yong)(yong)熱塑性橡(xiang)膠(jiao)，如(ru)熱塑性聚氨酯橡(xiang)膠(jiao)、聚酯橡(xiang)膠(jiao)等(deng)。膠(jiao)管(guan)(guan)因易(yi)彎曲(qu)、能(neng)緩沖(chong)、重(zhong)量(liang)(liang)輕(qing)及安裝(zhuang)使(shi)(shi)用(yong)(yong)(yong)(yong)方(fang)便(bian)等(deng)優點，用(yong)(yong)(yong)(yong)途十分廣泛，如(ru)農業(ye)上排灌農田(tian)、港(gang)灣疏浚(jun)中(zhong)吸排泥漿，飛機(ji)、坦(tan)克(ke)、汽(qi)車及許多機(ji)械裝(zhuang)備(bei)中(zhong)的(de)(de)液壓(ya)系統(tong)、氣(qi)(qi)動系統(tong)、燃(ran)油(you)系統(tong)均使(shi)(shi)用(yong)(yong)(yong)(yong)許多膠(jiao)管(guan)(guan)。氣(qi)(qi)割操作需要(yao)較大的(de)(de)氧(yang)氣(qi)(qi)輸出(chu)量(liang)(liang)，因此(ci)與氧(yang)氣(qi)(qi)表(biao)高壓(ya)端連接的(de)(de)氣(qi)(qi)瓶(ping)（或氧(yang)氣(qi)(qi)管(guan)(guan)道(dao)）閥(fa)門應全打(da)開，以便(bian)保(bao)證提(ti)供(gong)足(zu)夠的(de)(de)流(liu)量(liang)(liang)和(he)穩定的(de)(de)壓(ya)力，防(fang)止低(di)壓(ya)表(biao)雖(sui)已表(biao)示(shi)工作壓(ya)力，但使(shi)(shi)用(yong)(yong)(yong)(yong)時(shi)壓(ya)力突(tu)然下降，此(ci)時(shi)容(rong)易(yi)發生回火，并可能(neng)倒燃(ran)進入(ru)氧(yang)氣(qi)(qi)膠(jiao)管(guan)(guan)而(er)引(yin)起爆(bao)炸。在保(bao)存(cun)(cun)、運輸和(he)使(shi)(shi)用(yong)(yong)(yong)(yong)膠(jiao)管(guan)(guan)時(shi)必須注意維(wei)護(hu)，保(bao)持膠(jiao)管(guan)(guan)的(de)(de)清潔和(he)不(bu)受損壞(huai)。例如(ru)避(bi)免陽光照射，雨雪浸淋、防(fang)止與酸、堿、油(you)類及其(qi)他有機(ji)溶劑等(deng)影(ying)響膠(jiao)管(guan)(guan)質(zhi)(zhi)(zhi)量(liang)(liang)的(de)(de)物質(zhi)(zhi)(zhi)接觸。存(cun)(cun)放溫(wen)度為(wei)-15～40℃，距離熱源應不(bu)小(xiao)于1m.如(ru)果由(you)于保(bao)存(cun)(cun)和(he)使(shi)(shi)用(yong)(yong)(yong)(yong)時(shi)維(wei)護(hu)不(bu)善(shan)，或膠(jiao)管(guan)(guan)使(shi)(shi)用(yong)(yong)(yong)(yong)日久老(lao)化脆硬，這些膠(jiao)管(guan)(guan)內的(de)(de)硫磺質(zhi)(zhi)(zhi)被(bei)分解(jie)出(chu)來(lai)，常常會(hui)因此(ci)引(yin)起回火爆(bao)炸事故。
