In the activated carbon industry, high-temperature Steam Pipes are used in Rotary Kilns to activate charcoal. High temperature steam is used in rotary kiln to activate charcoal in activated carbon industry, steam pipe is inserted in the kiln under high temperature conditional environment. Excessive heat Steam, which is constantly and uniformly distributed across the activation region, is at the centre of the activation phase. The aim of this research is to look into the fractures that occur in the steam pipe during the process in the heat affected region. Two types of pipes were analysed using the finite element analysis method: those with straight holes and those without. To investigate the failure, total deformation, equal stress, and temperature distributions were calculated. A pipe's maximum holding time during the process will cause fractures to form, reducing the pipe's lifespan. Periodical cleaning and clinker removal of the pipe will increase the life of a pipe and the same time production of the respective product should not be affected.
