大連軟管總成主要用于(yu)礦(kuang)井液壓(ya)(ya)支架、油田開采，適宜(yi)于(yu)工(gong)(gong)程建筑、起(qi)重(zhong)(zhong)運輸、冶金鍛壓(ya)(ya)、礦(kuang)山設備、船舶、注(zhu)塑機(ji)(ji)械、農業機(ji)(ji)械、各種(zhong)機(ji)(ji)床以及各工(gong)(gong)業部門機(ji)(ji)械化(hua)、自(zi)動(dong)化(hua)液壓(ya)(ya)系統中輸送(song)具(ju)有一定壓(ya)(ya)力和溫度的石(shi)油基(ji)，如礦(kuang)物油、可(ke)溶性油、液壓(ya)(ya)油、燃油、潤滑油及水基(ji)液體(ti)，如乳化(hua)液、油水乳濁液、水等(deng)和液體(ti)傳(chuan)動(dong)用，最高耐工(gong)(gong)作(zuo)壓(ya)(ya)力可(ke)達60MPa。軟管(guan)規(gui)定的工(gong)(gong)作(zuo)壓(ya)(ya)力通常(chang)情況下(xia)不(bu)能(neng)小于(yu)最大系統壓(ya)(ya)力,只有在不(bu)常(chang)使(shi)(shi)用的情況下(xia),才允許提高20%；對于(yu)使(shi)(shi)用頻繁、經常(chang)彎扭者要降低40%。系統的沖擊壓(ya)(ya)力若(ruo)高于(yu)軟管(guan)規(gui)定的工(gong)(gong)作(zuo)壓(ya)(ya)力，不(bu)僅降低液壓(ya)(ya)軟管(guan)使(shi)(shi)用壽命，且可(ke)能(neng)導(dao)致(zhi)人身(shen)設備事(shi)故。這種(zhong)氧化(hua)層極薄，透過它可(ke)以看到不(bu)銹鋼表(biao)(biao)面的自(zi)然光澤，使(shi)(shi)不(bu)銹鋼具(ju)有獨特的表(biao)(biao)面。而且，如果損壞了表(biao)(biao)層，所暴(bao)露出(chu)的鋼表(biao)(biao)面會和大氣反應進行(xing)自(zi)我修理，重(zhong)(zhong)新形成這種(zhong)"鈍化(hua)膜"，繼續起(qi)保護作(zuo)用。
