钛管在换热器中的使用及制造

Analysis of manufacture and application of titanium tube heat exchanger

钛材具有比强度高、耐腐蚀性强、换热效果好的特点,近年来被广泛用于氯碱行业、化工原料行业的压力容器制造。使用钛换热管的换热器比一般使用不锈钢换热管的换热器换热效果高十几倍,而且设备使用寿命长。介绍了钛管换热器的结构特点和主要技术参数、管程主要材料的选择及其制造要点。

Titanium has a high specific strength, corrosion resistance and excellent heat transfer characteristics. In recent years, Titani- um had been widely used in chlor-alkali industry, chemicals industry and pressure vessels. Titanium tubes heat exchanger not only pos- sessed a long operation life, but also the efficiency of titanium tubes heat exchanger was 10 times higher than that of stainless steel heat exchanger. In this article the structure of titanium tube heat exchanger characteristics, main technical parameters of the main tube ma- terial selection and manufacturing points were described.
