由換熱器的損壞原因來看,腐蝕是一個(gè)十分重要的原因,而且換熱器的腐蝕是大量的普遍存在的,能夠解決好腐蝕問題,就等于解決了換熱器損壞的根本。要想防止換熱器的腐蝕,就得弄清楚腐蝕的根源,現(xiàn)就換熱器的腐蝕的原因從以下幾方面進(jìn)行討論。一、換熱器的用材的選擇：使用何種材料的決定因素是其經(jīng)濟(jì)性,管子材料有不銹鋼,銅鎳合金,鎳基合金,鈦和鋯等,除了工業(yè)上不能使用焊接管的情況以外都使用了焊接管,耐蝕材料*用于管程,殼程材料是碳鋼。二、換熱器的金屬腐蝕：金屬腐蝕的原理：金屬腐蝕是指在周圍介質(zhì)的化學(xué)或電化學(xué)的作用下,并且經(jīng)常是在和物理、機(jī)械或生物學(xué)因素的共同作用下金屬產(chǎn)生的破壞,也即金屬在它所處環(huán)境的作用下所產(chǎn)生破壞。換熱器幾種常見的腐蝕破壞類型：1、均勻腐蝕，在整個(gè)暴露于介質(zhì)的表面上,或者在較大的面積上產(chǎn)生的,宏觀上均勻的腐蝕破壞叫均勻腐蝕。2、接觸腐蝕，兩種電位不同的金屬或合金互相接觸,并浸于電解質(zhì)溶解質(zhì)溶液中,它們之間就有電流通過,電位正的金屬腐蝕速度降低,電位負(fù)的金屬腐蝕速度增加。3、選擇性腐蝕，合金中某一元素由于腐蝕,優(yōu)先進(jìn)入介質(zhì)的現(xiàn)象稱為選擇性腐蝕。4、孔蝕集中在金屬表面?zhèn)€別小點(diǎn)上深度較大的腐蝕稱為孔蝕。換熱器維修清洗的方法？</p><div

不銹鋼中其余添加元素也均發(fā)揮不同作用。像Mo會(huì)在一定程度上抵消氯離子引起的腐蝕，但是也有一個(gè)適用范圍。常用不銹鋼：304，316屬于奧氏體不銹鋼，其牌號(hào)為國(guó)外叫法的簡(jiǎn)寫（一般均為進(jìn)口），為300系列。美國(guó)牌號(hào)是美國(guó)鋼鐵協(xié)會(huì)AISI標(biāo)準(zhǔn)，日本是日本工業(yè)協(xié)會(huì)標(biāo)準(zhǔn)SUS。中國(guó)主要用成分表示，見下表。304、304L、316、316L的成分區(qū)別。L的含義是Low,表示更低含量的碳。帶L的焊接性能好，數(shù)字一樣的話，成分除碳以外其余成分無(wú)大區(qū)別。又由于316與316L價(jià)格差別不大，故直接選用316L。從成分表中可以看出304與316比較大區(qū)別為Mo（鉬）含量不同，所以316抗氯離子濃度能力要比304強(qiáng)。也是我們選用304還是316的主要依據(jù)。兩種材質(zhì)在耐受的氯離子濃度見下頁(yè)表格，板材的補(bǔ)充說明：板片常用材料的特點(diǎn)和使用條件補(bǔ)充評(píng)價(jià)材料耐蝕性好壞的指標(biāo)是“耐局部腐蝕當(dāng)量PRE”值越大則耐腐蝕性越好。主要是Cr、MO、Ni的含量決定。1）304不銹鋼：使用于有機(jī)和無(wú)機(jī)介質(zhì)中，濃度＜30%溫度＜＝100/濃度﹥30%溫度﹤50的硝酸溫度﹤100的各種濃度的碳酸、氨水和醇類。304L的材料基本和304材料一樣，可焊接性更好，可以用作焊接式換熱器。2）316L天然冷卻水、冷卻塔水、軟化水、碳酸。尋找板式換熱器合作伙伴。廣西節(jié)約空間換熱器加盟</p><p
