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(qing)潔，內部(bu)應(ying)沖洗干凈，特別是輸(shu)酸管(guan)(guan)(guan)(guan)(guan)(guan)、噴(pen)霧管(guan)(guan)(guan)(guan)(guan)(guan)、灰漿管(guan)(guan)(guan)(guan)(guan)(guan)。捆綁(bang)法適用于壓力在16MPa以下(xia)的軟(ruan)管(guan)(guan)(guan)(guan)(guan)(guan)破裂(lie)的應(ying)急搶修。防(fang)止外來物體進入管(guan)(guan)(guan)(guan)(guan)(guan)腔，阻礙(ai)輸(shu)送流體，質量差的膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)(guan)會出現：膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)(guan)壁厚薄不(bu)均；鋼(gang)絲(si)編織過緊、過松或鋼(gang)絲(si)層數過少，損壞設備。要避免膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)(guan)破裂(lie)的情況，因此要做到勤(qin)檢查，多保養。膠(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)(guan)工業(ye)的發展主要依(yi)賴于煤炭、鋼(gang)鐵(tie)、水泥、港(gang)口、礦山、石油(you)、汽車(che)、紡織、輕工、機械等(deng)(deng)工業(ye)的發展，包(bao)括了更大范圍(wei)的金屬軟(ruan)管(guan)(guan)(guan)(guan)(guan)(guan)、波紋管(guan)(guan)(guan)(guan)(guan)(guan)、液壓軟(ruan)管(guan)(guan)(guan)(guan)(guan)(guan)等(deng)(deng)。
