Abstract

Flare system is a system which functions to burn the remaining gas resulting from the processing of oil and gas and dangerous gases. In the flare system there are several lines, one of which is steam tracing. Where this steam tracing functions so that the fluid in the pipe does not experience freezing by maintaining high temperatures in the pipe so that the fluid can be pumped or flowed. In this steam tracing system there are several pipe points which are looped by compression bending. The pipe material used is carbon steel A 53 Grade B with sizes 3/4, 1, and 1 1/4 inch, each pipe is bent with a radius of 130°, 140°, 150°, where the results of the bending are analyzed by the method modeling using ANSYS Static Structural software with the aim to get the value of the corrosion rate that occurs in three variations of pipe size and three variations of the bending angle. The results of the analysis found that the highest corrosion rate occurs in pipes measuring 1/14 "with a bending angle of 130 °, while the lifetime value of an A53 grade b carbon steel pipe is found in the A53 grade B carbon steel pipe 1" with a bending angle of 150.
