由于钛材具有高的比强度和良好的综合机械性能,以及优良的抗腐蚀性能,特别是抗冲刷腐蚀性能,国外最早用于石油化工设备,海水淡化装置和核电站的热交换器。我国钛管热交换器在民用部门应用始于七十年代初期,首先是在化工部门应用。因受价格及成材能力的限制,钛管在电站凝汽器中应用起步较晚。1979年才开始进行规模的试验研 Due to its high specific strength and good overall mechanical properties, as well as its excellent corrosion resistance, especially its erosion resistance, titanium is the first heat exchanger used in petrochemical plants, desalination plants and nuclear power plants. China’s titanium tube heat exchanger applications in the civil sector began in the early 1970s, the first is the chemical sector applications. Due to the price and the ability to become limited, titanium tube condenser in the power plant started late. 1979 began only large-scale pilot study
