style="text-indent:25px">鋁合金管是無縫鋼管的一種，其性能要比一般的無縫鋼管高很多，因為這種鋼管里面含Cr比較多，其耐高溫、耐低溫、耐腐蝕的性能是其他無縫鋼管比不上的，所以合金管在石油、航天、化工、電力、鍋爐、**等行業(yè)的用途比較普遍。內(nèi)表面光潔，自我氧化層耐腐蝕。壓縮空氣壓損小，節(jié)能，管道美觀，簡潔，安裝方便，快插為主。安裝成本很低，方便拆裝、移動、修改。鋁是一種活潑金屬，在空氣中會迅速跟氧結(jié)合，在表面形成一層堅韌的氧化鋁薄膜，這層膜不但能防止鋁的內(nèi)層繼續(xù)與氧結(jié)合，起到保護(hù)作用，而且對許多腐蝕性介質(zhì)（如98%的濃硝酸、碳酸氫銨、尿素、醋蠟、甲醛、過氧化氫等）也有很強(qiáng)的抵抗力，鋁的純度越高，耐腐蝕性就越強(qiáng)。由于有較好的耐腐蝕性能，制造出的鋁合金管道在化學(xué)工業(yè)、食品工業(yè)中得到普遍的應(yīng)用。氨氣管道設(shè)計施工壓力管道設(shè)計施工就選興鼎。</p><div
