大連軟管總成主要用于(yu)(yu)礦(kuang)井液(ye)壓(ya)(ya)支架、油(you)(you)田開(kai)采，適宜于(yu)(yu)工(gong)程建筑、起(qi)重(zhong)運(yun)輸、冶金鍛壓(ya)(ya)、礦(kuang)山設備、船舶、注塑機(ji)械、農業機(ji)械、各種(zhong)(zhong)機(ji)床以(yi)及各工(gong)業部門機(ji)械化(hua)(hua)、自動化(hua)(hua)液(ye)壓(ya)(ya)系(xi)統(tong)(tong)(tong)中輸送具有一定壓(ya)(ya)力和(he)(he)溫度的(de)石油(you)(you)基，如(ru)礦(kuang)物(wu)油(you)(you)、可溶(rong)性油(you)(you)、液(ye)壓(ya)(ya)油(you)(you)、燃油(you)(you)、潤滑油(you)(you)及水(shui)基液(ye)體，如(ru)乳化(hua)(hua)液(ye)、油(you)(you)水(shui)乳濁液(ye)、水(shui)等和(he)(he)液(ye)體傳動用，最高耐工(gong)作壓(ya)(ya)力可達(da)60MPa。軟(ruan)管(guan)規(gui)定的(de)工(gong)作壓(ya)(ya)力通常(chang)情(qing)況(kuang)下(xia)不(bu)能小于(yu)(yu)最大系(xi)統(tong)(tong)(tong)壓(ya)(ya)力,只有在不(bu)常(chang)使(shi)用的(de)情(qing)況(kuang)下(xia),才(cai)允許提高20%；對于(yu)(yu)使(shi)用頻繁、經常(chang)彎(wan)扭者要降低40%。系(xi)統(tong)(tong)(tong)的(de)沖擊壓(ya)(ya)力若高于(yu)(yu)軟(ruan)管(guan)規(gui)定的(de)工(gong)作壓(ya)(ya)力，不(bu)僅降低液(ye)壓(ya)(ya)軟(ruan)管(guan)使(shi)用壽命，且(qie)可能導致人身設備事(shi)故。這種(zhong)(zhong)氧(yang)化(hua)(hua)層(ceng)極(ji)薄，透過它可以(yi)看到不(bu)銹鋼表(biao)面(mian)的(de)自然光澤，使(shi)不(bu)銹鋼具有獨特的(de)表(biao)面(mian)。而(er)且(qie)，如(ru)果損(sun)壞了(le)表(biao)層(ceng)，所(suo)暴露出的(de)鋼表(biao)面(mian)會和(he)(he)大氣反應進行自我修理，重(zhong)新形(xing)成這種(zhong)(zhong)"鈍化(hua)(hua)膜"，繼續(xu)起(qi)保護作用。
