Major items of equipment of process plants are piping and heat exchangers. Their typical troubles with aging are mainly caused by scale adhesion and erosion-corrosion. The former decreases flow rate, pressure and heat transfer performance, the latter breaks piping and heat exchanger tubes. Therefore, the purpose of this study is to derive the diagnostic method of pipe thickness which is more effective than the monitoring pressure. In this paper, the diagnostic method of pipe thickness in water line is developed experimentally. It is based on the phase of the transfer function of low-side pressure to high-side pressure in the test section. The experimental results show that this diagnostic method is superior to monitoring pressure on detecting a changing pipe thickness.
