由換熱器的損壞原因來(lái)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(guò),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。湖南供暖換熱器寬通道焊接式板式換熱器的優(yōu)點(diǎn)。</p><div
