Comparative Analysis between SA-516 Gr 70 Material with SA-537 Class 2 Material in Shell Pressure Vessel Fabrication Process

Abstract

Pressure vessel is a container to accommodate or store pressure fluids, both liquid and gas fluids which both have different pressures and temperatures. The pressure on the walls and body of the pressure vessel must be taken seriously, because it complies with applicable international design standards and priority the safety and security of workers. Research was conducted on a pressure vessel that aims to determine whether using the specified temperature affects the thickness of the shell to meet ASME standards. Research on shell components using SA-516 Gr 70 material and SA-537 material. Experiments were carried out with each material at temperatures of 250 C, 235 C, 343 C, where each material and temperature different thickness. The results of this research meet ASME standards because during the trial the thickness of the shell is not less than the actual thickness specified by the drawing. Which each experiment has an average value, namely SA-516 Gr 70 at 250 C with an average value of 13.25 mm, then at a temperature of 235 C the average value is 18.25 mm, at a temperature of 343 C the average value is 22.55 mm. While SA-537 Class 2 at a temperature of 250 C average value of 25.72 mm, at a temperature of 235 C average value of 18.31, at a temperature of 343 C average value of 13.82 mm.
