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(jie)，內部(bu)應沖洗干凈(jing)，特別是輸酸管(guan)(guan)(guan)(guan)、噴霧管(guan)(guan)(guan)(guan)、灰漿管(guan)(guan)(guan)(guan)。捆綁(bang)法(fa)適用于(yu)壓(ya)力在(zai)16MPa以下的(de)(de)軟(ruan)(ruan)管(guan)(guan)(guan)(guan)破裂的(de)(de)應急搶修。防止外來物體(ti)(ti)進(jin)入管(guan)(guan)(guan)(guan)腔，阻礙輸送流體(ti)(ti)，質量差的(de)(de)膠管(guan)(guan)(guan)(guan)會出現：膠管(guan)(guan)(guan)(guan)壁厚薄不(bu)均；鋼絲編織過緊、過松或(huo)鋼絲層數過少，損壞設備。要避免膠管(guan)(guan)(guan)(guan)破裂的(de)(de)情況，因(yin)此要做到(dao)勤檢查，多(duo)保養。膠管(guan)(guan)(guan)(guan)工(gong)(gong)(gong)業的(de)(de)發(fa)展(zhan)主要依賴(lai)于(yu)煤炭、鋼鐵、水泥、港口、礦山、石油、汽車、紡織、輕工(gong)(gong)(gong)、機械等工(gong)(gong)(gong)業的(de)(de)發(fa)展(zhan)，包(bao)括了更大(da)范圍的(de)(de)金(jin)屬軟(ruan)(ruan)管(guan)(guan)(guan)(guan)、波紋管(guan)(guan)(guan)(guan)、液壓(ya)軟(ruan)(ruan)管(guan)(guan)(guan)(guan)等。
