How do you choose a cooling tower for a coastal project? 闭式冷却塔 材质上我们要怎么选择呢? It has been eroded by seawater all year round, and seawater contains a large amount of chloride ions. How do we choose the material of the closed cooling tower ? 10 多年选型和配套经验的闭式冷却塔厂家,无锡方舟流体就有做过不少这样的沿海项目,我们在闭式冷却塔面板和冷却器盘管上采用的是特殊的双相不锈钢。 As a closed cooling tower manufacturer with more than 10 years of selection and supporting experience, Wuxi Ark Fluid has done many such coastal projects. We use special dual-phase on the closed cooling tower panel and cooler coil stainless steel.

双相不锈钢( Duplex Stainless Steel ,简称 DSS ),指 铁素体 奥氏体 各约占 50% ,一般较少相的含量最少也需要达到 30% 的不锈钢。 The so-called Duplex Stainless Steel ( DSS ) refers to ferrite and austenite each accounting for about 50% . Generally, the content of less phases also needs to reach at least 30% of stainless steel. 点蚀 缝隙腐蚀 应力腐蚀 腐蚀疲劳 性能明显优于普通的 奥氏体不锈钢 ,可以与高合金奥氏体不锈钢媲美。 In terms of corrosion resistance, especially in the harsh medium environment (such as sea water, high chloride ion content), the resistance to pitting , crevice corrosion , stress corrosion and corrosion fatigue of duplex stainless steel is significantly better than ordinary austenite Stainless steel , comparable to high-alloy austenitic stainless steel. 闭式冷却塔 面板当然使用寿命更久。 Duplex stainless steel closed cooling tower panels certainly have a longer life.

Duplex stainless steel has good welding performance. Compared with ferritic stainless steel and austenitic stainless steel, it is not like the heat affected zone of ferritic stainless steel. Due to the severe coarsening of grains, the plastic toughness is greatly reduced. Unlike austenitic stainless steel, it is more sensitive to welding hot cracks. So the cooler coil performance of duplex stainless steel will be better.

闭式冷却塔 ,已使用三年多,冷却效果良好,冷却塔面板也没有任何腐蚀倾向,客户评价好。 The central air-conditioning cooling on an island in Hainan uses this closed cooling tower customized by Ark Fluid for the coastal area alone . It has been used for more than three years, and the cooling effect is good. The cooling tower panel does not have any tendency to corrode, and the customer's evaluation is good.
