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，內部應沖洗干凈，特別是輸酸管(guan)(guan)(guan)(guan)(guan)、噴(pen)霧(wu)管(guan)(guan)(guan)(guan)(guan)、灰漿管(guan)(guan)(guan)(guan)(guan)。捆綁(bang)法適用于壓力在16MPa以下的軟(ruan)管(guan)(guan)(guan)(guan)(guan)破裂的應急搶(qiang)修。防(fang)止(zhi)外來物(wu)體進(jin)入管(guan)(guan)(guan)(guan)(guan)腔，阻礙輸送流體，質量(liang)差的膠管(guan)(guan)(guan)(guan)(guan)會(hui)出(chu)現：膠管(guan)(guan)(guan)(guan)(guan)壁厚薄(bo)不均；鋼(gang)絲編(bian)織(zhi)過緊、過松或鋼(gang)絲層數過少(shao)，損(sun)壞設備。要(yao)(yao)避免膠管(guan)(guan)(guan)(guan)(guan)破裂的情況，因此要(yao)(yao)做到勤(qin)檢查，多保養(yang)。膠管(guan)(guan)(guan)(guan)(guan)工(gong)(gong)業的發展主(zhu)要(yao)(yao)依賴于煤炭、鋼(gang)鐵、水泥、港口、礦山、石油、汽車、紡織(zhi)、輕工(gong)(gong)、機械等工(gong)(gong)業的發展，包括了更大范圍的金屬軟(ruan)管(guan)(guan)(guan)(guan)(guan)、波紋管(guan)(guan)(guan)(guan)(guan)、液壓軟(ruan)管(guan)(guan)(guan)(guan)(guan)等。
