膠管近年來(lai)，開始采(cai)用(yong)(yong)(yong)(yong)熱塑(su)性(xing)(xing)橡(xiang)膠(jiao)，如熱塑(su)性(xing)(xing)聚(ju)氨(an)酯橡(xiang)膠(jiao)、聚(ju)酯橡(xiang)膠(jiao)等(deng)。膠(jiao)管(guan)(guan)因(yin)易彎(wan)曲、能緩沖、重量(liang)輕及(ji)安(an)裝(zhuang)使(shi)用(yong)(yong)(yong)(yong)方(fang)便等(deng)優點，用(yong)(yong)(yong)(yong)途十(shi)分(fen)廣泛，如農(nong)業上排(pai)灌(guan)農(nong)田、港灣疏浚中吸排(pai)泥漿(jiang)，飛(fei)機、坦克、汽車(che)及(ji)許多(duo)機械(xie)裝(zhuang)備中的(de)(de)液壓(ya)(ya)系統、氣(qi)(qi)動系統、燃油系統均使(shi)用(yong)(yong)(yong)(yong)許多(duo)膠(jiao)管(guan)(guan)。氣(qi)(qi)割操作需(xu)要較大的(de)(de)氧(yang)(yang)氣(qi)(qi)輸(shu)(shu)出(chu)(chu)量(liang)，因(yin)此與(yu)氧(yang)(yang)氣(qi)(qi)表(biao)(biao)高(gao)壓(ya)(ya)端連接的(de)(de)氣(qi)(qi)瓶（或氧(yang)(yang)氣(qi)(qi)管(guan)(guan)道）閥門應全打開，以便保證提供足(zu)夠的(de)(de)流量(liang)和(he)(he)穩定(ding)的(de)(de)壓(ya)(ya)力(li)，防止(zhi)低壓(ya)(ya)表(biao)(biao)雖已表(biao)(biao)示工作壓(ya)(ya)力(li)，但使(shi)用(yong)(yong)(yong)(yong)時(shi)(shi)壓(ya)(ya)力(li)突然下降，此時(shi)(shi)容易發生回火，并可(ke)能倒燃進(jin)入氧(yang)(yang)氣(qi)(qi)膠(jiao)管(guan)(guan)而引起爆炸(zha)。在保存(cun)(cun)、運輸(shu)(shu)和(he)(he)使(shi)用(yong)(yong)(yong)(yong)膠(jiao)管(guan)(guan)時(shi)(shi)必須(xu)注意維(wei)護(hu)(hu)，保持(chi)膠(jiao)管(guan)(guan)的(de)(de)清潔和(he)(he)不(bu)受(shou)損壞。例如避(bi)免陽(yang)光照射，雨雪浸(jin)淋、防止(zhi)與(yu)酸、堿、油類(lei)及(ji)其他(ta)有機溶劑等(deng)影響膠(jiao)管(guan)(guan)質量(liang)的(de)(de)物質接觸。存(cun)(cun)放(fang)溫度(du)為(wei)-15～40℃，距離熱源(yuan)應不(bu)小于1m.如果(guo)由于保存(cun)(cun)和(he)(he)使(shi)用(yong)(yong)(yong)(yong)時(shi)(shi)維(wei)護(hu)(hu)不(bu)善，或膠(jiao)管(guan)(guan)使(shi)用(yong)(yong)(yong)(yong)日久老化(hua)脆硬(ying)，這些膠(jiao)管(guan)(guan)內(nei)的(de)(de)硫磺質被(bei)分(fen)解(jie)出(chu)(chu)來(lai)，常常會因(yin)此引起回火爆炸(zha)事故。
