大連軟管總成主要(yao)用(yong)(yong)于礦(kuang)井液壓(ya)(ya)(ya)支架、油田開(kai)采，適宜于工(gong)(gong)程建筑、起重(zhong)運輸(shu)、冶金鍛壓(ya)(ya)(ya)、礦(kuang)山設備(bei)、船舶、注(zhu)塑機(ji)(ji)械(xie)、農業機(ji)(ji)械(xie)、各(ge)(ge)種機(ji)(ji)床以及各(ge)(ge)工(gong)(gong)業部門機(ji)(ji)械(xie)化、自(zi)動化液壓(ya)(ya)(ya)系(xi)(xi)統中輸(shu)送具有一定壓(ya)(ya)(ya)力(li)和(he)溫度的(de)石油基，如礦(kuang)物(wu)油、可(ke)溶性(xing)油、液壓(ya)(ya)(ya)油、燃油、潤滑油及水(shui)(shui)基液體，如乳(ru)化液、油水(shui)(shui)乳(ru)濁(zhuo)液、水(shui)(shui)等(deng)和(he)液體傳動用(yong)(yong)，最(zui)高(gao)耐(nai)工(gong)(gong)作壓(ya)(ya)(ya)力(li)可(ke)達60MPa。軟管(guan)規定的(de)工(gong)(gong)作壓(ya)(ya)(ya)力(li)通常情(qing)況下不(bu)能(neng)小于最(zui)大系(xi)(xi)統壓(ya)(ya)(ya)力(li),只有在不(bu)常使(shi)用(yong)(yong)的(de)情(qing)況下,才允許提高(gao)20%；對于使(shi)用(yong)(yong)頻繁(fan)、經(jing)常彎扭者要(yao)降低(di)40%。系(xi)(xi)統的(de)沖擊(ji)壓(ya)(ya)(ya)力(li)若高(gao)于軟管(guan)規定的(de)工(gong)(gong)作壓(ya)(ya)(ya)力(li)，不(bu)僅降低(di)液壓(ya)(ya)(ya)軟管(guan)使(shi)用(yong)(yong)壽(shou)命，且(qie)可(ke)能(neng)導致人身設備(bei)事故。這種氧(yang)化層極薄(bo)，透過它可(ke)以看到不(bu)銹(xiu)鋼表面的(de)自(zi)然光澤，使(shi)不(bu)銹(xiu)鋼具有獨(du)特的(de)表面。而且(qie)，如果損(sun)壞(huai)了表層，所暴(bao)露出的(de)鋼表面會和(he)大氣反應進行(xing)自(zi)我(wo)修理，重(zhong)新(xin)形(xing)成(cheng)這種"鈍化膜"，繼續起保護作用(yong)(yong)。
