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(xi)干凈(jing)，特別是輸酸(suan)管(guan)(guan)(guan)(guan)(guan)、噴霧(wu)管(guan)(guan)(guan)(guan)(guan)、灰漿管(guan)(guan)(guan)(guan)(guan)。捆綁法適用于壓力在(zai)16MPa以下(xia)的(de)(de)軟管(guan)(guan)(guan)(guan)(guan)破(po)裂的(de)(de)應急搶修。防止外來物體進入管(guan)(guan)(guan)(guan)(guan)腔，阻礙輸送(song)流體，質量差(cha)的(de)(de)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)會出現：膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)壁厚(hou)薄不均；鋼(gang)絲編織過(guo)緊、過(guo)松或(huo)鋼(gang)絲層數過(guo)少(shao)，損壞設備。要(yao)避免膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)破(po)裂的(de)(de)情(qing)況，因此(ci)要(yao)做到勤檢查，多(duo)保養。膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)工(gong)(gong)業(ye)的(de)(de)發(fa)展(zhan)主要(yao)依賴于煤炭、鋼(gang)鐵、水(shui)泥、港口、礦山、石油、汽車、紡織、輕工(gong)(gong)、機械等工(gong)(gong)業(ye)的(de)(de)發(fa)展(zhan)，包括了(le)更大范圍的(de)(de)金屬軟管(guan)(guan)(guan)(guan)(guan)、波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)、液壓軟管(guan)(guan)(guan)(guan)(guan)等。
