Sažetak
The condition of pipe material used in an ammonia production plant is analyzed. The pipes are made of high alloyed Ni-Cr and Cr-Mo alloyed steel for high temperature (523°C) and high pressure (126 bar) operation. Media inside the pipes is superheated steam that is heated by natural gas combustion. The condition of pipes that have been exposed to high pressure and temperature is analyzed, and the corrosion damages are observed at outer side of the pipe. These damages caused the decrease of the mechanical properties, and therefore, the lifecycle of the pipes also decreased
