由于钛的优良的耐蚀特性,钛管在化工生产中获得了广泛应用,也日益成为电力工业部门制作冷凝器和冷却器的标准用材。尽管钛原料费用高,但它能避免昂贵的腐蚀消耗,因此用钛仍是经济合理的。特别是,选用壁厚为0.4～0.9毫米的缝焊管,经济效益比用无缝管更好,因为加工壁厚小于0.9毫米的无缝管困难多,要花费更多的钱。 Due to the excellent corrosion resistance of titanium, titanium tubes are widely used in chemical production and are increasingly becoming standard materials for condensers and coolers in the power industry. Despite the high cost of raw titanium, it avoids costly corrosion and therefore titanium is still economically justified. In particular, the use of seam welded pipe with wall thickness of 0.4-0.9 mm is more economical than seamless pipe, because it is more difficult and cost more to process seamless pipe with wall thickness less than 0.9 mm.
