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(chi)清潔(jie)，內部應沖洗干凈，特(te)別是輸酸管(guan)(guan)(guan)(guan)(guan)、噴霧管(guan)(guan)(guan)(guan)(guan)、灰漿管(guan)(guan)(guan)(guan)(guan)。捆綁(bang)法適(shi)用(yong)于(yu)壓力(li)在16MPa以下(xia)的軟管(guan)(guan)(guan)(guan)(guan)破裂(lie)的應急(ji)搶修。防止外(wai)來物體(ti)進入管(guan)(guan)(guan)(guan)(guan)腔，阻礙輸送流體(ti)，質量差的膠(jiao)管(guan)(guan)(guan)(guan)(guan)會出現：膠(jiao)管(guan)(guan)(guan)(guan)(guan)壁厚(hou)薄不均；鋼絲(si)編織過緊、過松或鋼絲(si)層(ceng)數過少，損壞設備(bei)。要(yao)避免膠(jiao)管(guan)(guan)(guan)(guan)(guan)破裂(lie)的情況，因此要(yao)做到勤檢查，多(duo)保養。膠(jiao)管(guan)(guan)(guan)(guan)(guan)工(gong)(gong)業的發展主要(yao)依賴于(yu)煤(mei)炭、鋼鐵(tie)、水泥、港口、礦山、石油(you)、汽車、紡織、輕工(gong)(gong)、機械(xie)等(deng)工(gong)(gong)業的發展，包括了更大(da)范圍(wei)的金屬軟管(guan)(guan)(guan)(guan)(guan)、波(bo)紋管(guan)(guan)(guan)(guan)(guan)、液壓軟管(guan)(guan)(guan)(guan)(guan)等(deng)。
