Abstract

The transport tank is a horizontal type of pressure vessel used to transport LPG in the oil and gas industry. LPG transport tank pressure vessels result in fatigue in the pressure vessel so fatigue resistance is important for further analysis. The toughness of the material also needs to be analyzed through an experimental approach by adjusting the working temperature conditions of the pressure vessel and also to find out the fracture characteristics due to testing at different temperature conditions. The purpose of this study was to analyze the impact toughness of ASTM A-36 steel joints which are commonly used in pressure vessels and to analyze the fatigue resistance using the fatigue test using the repeated bending method. The impact test results yielded an impact energy of 86.60 J and toughness of 1.095 J/〖mm〗^2 at a test temperature of 0°C. At 10°C the impact energy is 92.27 J with a toughness of 1.153 J/〖mm〗^2, and at 27°C the impact energy is 105.27 J with a toughness of 1.315 J/〖mm〗^2. The results of the fatigue test at 10⁰ angle loading produced a cycle of 67180,5, then at 11° loading angle obtained a cycle of 61066,5, and at 12° angle loading the cycle obtained was 52321,5, while fatigue testing at 13° angle loading obtained a cycle of 48112,5.
