钛-钢复合板设备的结构优化

Optimization for Structure of Equipment Made of Titanium-steel Clad Plate

近些年,钛制设备在我国的氯碱工业、尿素生产、精细化工、硝酸生产、PTA等行业得到了广泛应用,我国的钛需求量也逐年增高。国内设计、制造、使用钛制设备已有30余年的历史,积累了一些经验,掌握了一些设计、制造和使用技术。而今钛-钢复合板制设备占据了钛制设备的大部分应用,但钛-钢复合板制设备比钢制设备在设计、制造上具有更多的难度,需要将成熟、可靠的结构设计进行传播,并不断探寻更加合理、有效的结构形式。

The failures of holing, thining and leakage are often occurred in heat transfer plates in plate heat exchanger. In view of the high cost for heat transfer plate, to directly discard or replace old plates are unacceptable. In order to save the cost, the repair of failed plates is concerned by mantenance technicians. The weld repairing process for titanium heat transfer plate was studied in this article.
