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(bao)持清潔，內部應(ying)沖洗(xi)干(gan)凈，特別是輸(shu)酸管(guan)(guan)(guan)(guan)(guan)(guan)、噴霧(wu)管(guan)(guan)(guan)(guan)(guan)(guan)、灰漿管(guan)(guan)(guan)(guan)(guan)(guan)。捆綁法適用(yong)于壓力在16MPa以下的(de)軟管(guan)(guan)(guan)(guan)(guan)(guan)破裂(lie)(lie)的(de)應(ying)急搶(qiang)修。防止外(wai)來(lai)物體進入管(guan)(guan)(guan)(guan)(guan)(guan)腔，阻礙輸(shu)送流體，質量(liang)差的(de)膠(jiao)管(guan)(guan)(guan)(guan)(guan)(guan)會出現：膠(jiao)管(guan)(guan)(guan)(guan)(guan)(guan)壁厚(hou)薄不均；鋼絲(si)(si)編織(zhi)過緊、過松(song)或(huo)鋼絲(si)(si)層(ceng)數過少，損壞設備。要避免膠(jiao)管(guan)(guan)(guan)(guan)(guan)(guan)破裂(lie)(lie)的(de)情況，因此要做到(dao)勤檢(jian)查，多保(bao)養。膠(jiao)管(guan)(guan)(guan)(guan)(guan)(guan)工(gong)(gong)業的(de)發展主要依賴(lai)于煤(mei)炭(tan)、鋼鐵、水泥、港口(kou)、礦(kuang)山、石(shi)油(you)、汽車(che)、紡(fang)織(zhi)、輕工(gong)(gong)、機(ji)械等工(gong)(gong)業的(de)發展，包括了更大范圍的(de)金屬軟管(guan)(guan)(guan)(guan)(guan)(guan)、波紋管(guan)(guan)(guan)(guan)(guan)(guan)、液壓軟管(guan)(guan)(guan)(guan)(guan)(guan)等。
