膠管近年來(lai)，開始采(cai)用(yong)(yong)熱塑性(xing)橡膠(jiao)，如(ru)熱塑性(xing)聚氨(an)酯橡膠(jiao)、聚酯橡膠(jiao)等(deng)。膠(jiao)管(guan)(guan)(guan)因易(yi)彎曲、能緩沖、重(zhong)量輕及(ji)安裝使(shi)用(yong)(yong)方便等(deng)優(you)點，用(yong)(yong)途(tu)十分廣泛，如(ru)農業上排灌(guan)農田、港(gang)灣疏浚中(zhong)吸排泥漿(jiang)，飛機、坦克(ke)、汽(qi)車及(ji)許(xu)多機械裝備中(zhong)的(de)(de)液壓系統(tong)、氣(qi)動系統(tong)、燃油系統(tong)均使(shi)用(yong)(yong)許(xu)多膠(jiao)管(guan)(guan)(guan)。氣(qi)割操(cao)作需要較大的(de)(de)氧(yang)氣(qi)輸出量，因此與氧(yang)氣(qi)表(biao)(biao)高壓端連接(jie)的(de)(de)氣(qi)瓶（或(huo)氧(yang)氣(qi)管(guan)(guan)(guan)道(dao)）閥門應全(quan)打開，以便保(bao)證提供足夠的(de)(de)流(liu)量和穩(wen)定的(de)(de)壓力(li)(li)，防(fang)止(zhi)低壓表(biao)(biao)雖已表(biao)(biao)示工(gong)作壓力(li)(li)，但(dan)使(shi)用(yong)(yong)時(shi)(shi)(shi)(shi)壓力(li)(li)突然下降，此時(shi)(shi)(shi)(shi)容易(yi)發生回火，并可(ke)能倒(dao)燃進(jin)入氧(yang)氣(qi)膠(jiao)管(guan)(guan)(guan)而引起爆(bao)炸。在(zai)保(bao)存、運輸和使(shi)用(yong)(yong)膠(jiao)管(guan)(guan)(guan)時(shi)(shi)(shi)(shi)必(bi)須注意(yi)維(wei)護，保(bao)持膠(jiao)管(guan)(guan)(guan)的(de)(de)清潔(jie)和不(bu)受損壞。例如(ru)避免陽光照射，雨(yu)雪浸淋、防(fang)止(zhi)與酸、堿、油類及(ji)其他有機溶劑等(deng)影響(xiang)膠(jiao)管(guan)(guan)(guan)質量的(de)(de)物質接(jie)觸。存放溫(wen)度為-15～40℃，距(ju)離熱源應不(bu)小于(yu)1m.如(ru)果由于(yu)保(bao)存和使(shi)用(yong)(yong)時(shi)(shi)(shi)(shi)維(wei)護不(bu)善，或(huo)膠(jiao)管(guan)(guan)(guan)使(shi)用(yong)(yong)日久老化脆硬，這些膠(jiao)管(guan)(guan)(guan)內的(de)(de)硫(liu)磺質被(bei)分解出來(lai)，常常會因此引起回火爆(bao)炸事(shi)故。
