大連膠管結構主要由內膠層、中膠層、四層或多層交替纏繞的鋼絲增強層和外膠層組成，用以輸送氣體、液體、漿狀或粒狀物料的一類管狀橡膠制品。最高耐工作壓力可達70-120Mpa。將油管在纏繞機或編織機上纏繞上鍍銅鋼絲或鍍銅鋼絲繩，管壁的內外層均為耐油橡膠，中間為交叉編織鋼絲或纏繞鋼絲。膠管應(ying)保(bao)持清潔，內部應(ying)沖洗干(gan)凈，特別是輸酸管(guan)(guan)(guan)(guan)(guan)、噴霧(wu)管(guan)(guan)(guan)(guan)(guan)、灰漿管(guan)(guan)(guan)(guan)(guan)。捆綁法(fa)適用于壓力(li)在16MPa以下的軟管(guan)(guan)(guan)(guan)(guan)破裂(lie)(lie)的應(ying)急搶(qiang)修。防(fang)止外(wai)來(lai)物(wu)體進(jin)入管(guan)(guan)(guan)(guan)(guan)腔，阻(zu)礙(ai)輸送流體，質(zhi)量差的膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)會出現：膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)壁(bi)厚薄不均；鋼(gang)絲編織過緊(jin)、過松或鋼(gang)絲層數過少，損壞(huai)設備。要避免膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)破裂(lie)(lie)的情況(kuang)，因此要做(zuo)到勤檢查，多保(bao)養。膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)工(gong)(gong)業的發(fa)展主(zhu)要依賴于煤炭、鋼(gang)鐵、水泥、港(gang)口、礦山、石油、汽車、紡織、輕(qing)工(gong)(gong)、機械(xie)等工(gong)(gong)業的發(fa)展，包括了(le)更大(da)范(fan)圍(wei)的金屬(shu)軟管(guan)(guan)(guan)(guan)(guan)、波紋管(guan)(guan)(guan)(guan)(guan)、液壓軟管(guan)(guan)(guan)(guan)(guan)等。
