At the beginning, some leaks occur at the transmission pipe and disturb a production which cause a product loss. The material used in this installation is SS 316L, and it was used at 97,6-98,1% sulfuric acid solution and at the temperature between 84-88oC. To analize this problem, some observation and analysis methods were used, as material characterization, fracture surface analysis and computational fluid dynamics simulation. The result presents that this stainless steel could have a good corrosion resistance to sulfuric acid solution in low temperature less than 55°C, and not in higher temperature. The mixture of gas and fluid phase in this case and the velocity of the fluid flow inside the SS316L pipe promote a more severe corrosion impact to certain location of pipe wall and form a corrosion erosion damage pattern. CFD simulation indicates that in those damaged location, the value of wall shear stress was high. These results show that the relevant failure cause of this installation is corrosion erosion and clearly presented by the damage form at the pipe wall. In fact, some references present that SS 316L is not adequate in this operation condition, and it needs a highest grade of the alloys which have a highest corrosion resistance in this media.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]316 L stainless steel,Analysis method,CFD simulations,Computational fluid dynamics simulations,Erosion damage,Fluid-phase,Fracture surface analysis,High concentration,High temperature,Low temperatures,Material characterizations,Operation conditions,Pipe walls,Process industries,Severe corrosion,SS 316L,Sulfuric acid solution,Transmission pipes,Wall shear stress[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Corrosion erosion,High concentration sulfuric acid,High temperature,SS 316L,Wall Shear Stress[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
