CAUSE ANALYSIS FOR PROCESS AIR COILS LEAKAGE OF PRIMARY REFORMER
This article introduces the process of air coils leakage in the primary reformer.By testing the hardness,wall thickness,and crystal phase around the leakage site,it is determined that there is a 3～4 level spheroidization in the metallographic structure of the pipeline at the leakage site.The coil was repaired,replaced as a whole,and the protective measures were taken to solve the problem.
