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)保持清潔(jie)，內(nei)部(bu)應(ying)沖洗干凈，特(te)別是輸酸管(guan)(guan)(guan)(guan)(guan)、噴霧管(guan)(guan)(guan)(guan)(guan)、灰(hui)漿管(guan)(guan)(guan)(guan)(guan)。捆綁(bang)法適用于(yu)壓力在16MPa以(yi)下的(de)(de)軟(ruan)管(guan)(guan)(guan)(guan)(guan)破裂的(de)(de)應(ying)急搶修。防止外來物體進入管(guan)(guan)(guan)(guan)(guan)腔(qiang)，阻礙(ai)輸送流體，質量差(cha)的(de)(de)膠(jiao)管(guan)(guan)(guan)(guan)(guan)會出現：膠(jiao)管(guan)(guan)(guan)(guan)(guan)壁厚薄不均(jun)；鋼絲編織(zhi)過(guo)(guo)緊、過(guo)(guo)松(song)或鋼絲層數過(guo)(guo)少，損壞設備。要(yao)避免(mian)膠(jiao)管(guan)(guan)(guan)(guan)(guan)破裂的(de)(de)情況，因此(ci)要(yao)做到(dao)勤檢查，多保養。膠(jiao)管(guan)(guan)(guan)(guan)(guan)工(gong)(gong)業的(de)(de)發(fa)展(zhan)主要(yao)依(yi)賴于(yu)煤炭、鋼鐵、水泥、港口、礦山、石油、汽車、紡(fang)織(zhi)、輕工(gong)(gong)、機械等工(gong)(gong)業的(de)(de)發(fa)展(zhan)，包括了(le)更大范圍的(de)(de)金屬(shu)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。
