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)(ying)保(bao)持(chi)清(qing)潔，內(nei)部應(ying)(ying)沖洗干凈，特別是輸酸(suan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、噴霧管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、灰漿管(guan)(guan)(guan)(guan)(guan)(guan)(guan)。捆綁(bang)法適用于(yu)壓(ya)力在16MPa以下的(de)(de)軟管(guan)(guan)(guan)(guan)(guan)(guan)(guan)破(po)裂的(de)(de)應(ying)(ying)急搶修。防止外來物體(ti)進入管(guan)(guan)(guan)(guan)(guan)(guan)(guan)腔(qiang)，阻礙輸送流體(ti)，質量(liang)差(cha)的(de)(de)膠管(guan)(guan)(guan)(guan)(guan)(guan)(guan)會(hui)出(chu)現：膠管(guan)(guan)(guan)(guan)(guan)(guan)(guan)壁厚(hou)薄不(bu)均；鋼(gang)絲編織過緊、過松(song)或(huo)鋼(gang)絲層數過少(shao)，損壞設備。要避免(mian)膠管(guan)(guan)(guan)(guan)(guan)(guan)(guan)破(po)裂的(de)(de)情況，因此要做到勤檢查(cha)，多保(bao)養。膠管(guan)(guan)(guan)(guan)(guan)(guan)(guan)工(gong)業的(de)(de)發展主要依賴于(yu)煤炭、鋼(gang)鐵、水泥、港口、礦山、石油、汽車、紡織、輕工(gong)、機械等工(gong)業的(de)(de)發展，包括了更大范圍的(de)(de)金屬(shu)軟管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、波紋管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、液壓(ya)軟管(guan)(guan)(guan)(guan)(guan)(guan)(guan)等。
