大連膠管結構是由耐液體的合成橡膠內膠層、中膠層、Ⅰ或Ⅱ或Ⅲ層鋼絲編織增強層、及耐天候性能優良的合成橡膠外膠層組成。主要用于礦井液壓支架、油田開采，適宜于工程建筑、起重運輸、冶金鍛壓、礦山設備、船舶、注塑機械、農業機械、各種機床以及各工業部門機械化、自動化液壓系統中輸送具有一定壓力和溫度的石油基如礦物油、可溶性油、液壓油、燃油、潤滑油等液體、水基液體，如乳化液、油水乳濁液、水、氣體等和液體傳動用。膠管使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)注(zhu)意事項：由(you)于膠管品種復雜，結(jie)構多樣(yang)，加(jia)之使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)條件不一(yi)，因此膠管使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)壽命長短，不僅決(jue)(jue)定于質(zhi)量(liang)(liang)的好壞，同時(shi)也決(jue)(jue)定于正(zheng)(zheng)確使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)保(bao)養。所以即使(shi)(shi)(shi)(shi)產品有(you)高質(zhi)量(liang)(liang)，如(ru)不能正(zheng)(zheng)確地使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)和保(bao)養，也會嚴(yan)重影響(xiang)其(qi)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)質(zhi)量(liang)(liang)和壽命，甚(shen)至發生(sheng)不應有(you)的嚴(yan)重事故，對財物造成(cheng)損失。因此，它(ta)的使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)可信賴度要相對差一(yi)些。
