abstract

Reformer tubes are commonly used in process industry. They are high cost components. The service life of reformer tubes is primarily determined by creep damage. To successfully manage the reformer tubes requires balancing creep life against the production gains of higher temperatures. The key to this requires an ongoing knowledge of the condition of the tubes. Monitoring the diametrical change of the tubes caused by creep damage is one of the most popular methods used in industry. However, the available reformer tube diametrical checking systems are very expensive. This paper presents a novel mechanical sensing unit for reformer tube diametrical measuring. The system is low cost and meets the industrial company specified requirements. Test and field trials made on the prototype gave a very encouraging result. With further study, it is expected that a robust and cost effective reformer tube diametric measuring system can be developed.
