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。膠管應保持清潔，內部應沖(chong)洗干(gan)凈，特別(bie)是輸酸管(guan)(guan)(guan)(guan)(guan)、噴(pen)霧管(guan)(guan)(guan)(guan)(guan)、灰漿(jiang)管(guan)(guan)(guan)(guan)(guan)。捆(kun)綁(bang)法適用于壓(ya)力在16MPa以(yi)下的(de)軟管(guan)(guan)(guan)(guan)(guan)破裂的(de)應急(ji)搶修。防止外(wai)來物體進入(ru)管(guan)(guan)(guan)(guan)(guan)腔，阻礙輸送流體，質量差的(de)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)會出現(xian)：膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)壁(bi)厚薄(bo)不均；鋼絲編織(zhi)過緊、過松(song)或鋼絲層數過少，損壞設備。要(yao)避免(mian)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)破裂的(de)情況(kuang)，因此要(yao)做到勤檢查，多保養。膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)工(gong)(gong)業的(de)發展主要(yao)依賴(lai)于煤炭、鋼鐵、水泥、港口、礦山、石油、汽車、紡織(zhi)、輕工(gong)(gong)、機械等工(gong)(gong)業的(de)發展，包括了更大范圍的(de)金屬軟管(guan)(guan)(guan)(guan)(guan)、波(bo)紋管(guan)(guan)(guan)(guan)(guan)、液壓(ya)軟管(guan)(guan)(guan)(guan)(guan)等。
