Abstract	Piping system are necessary in the gas and steam power plant to distribute fluid from one equipment to the other equipment. To design a power plant based on code ASME B31.1. Design of piping systems for the main steam (low pressure) which serves to distribute low-pressure steam from the Heat Recovery Steam Generator (HRSG) to the steam turbine and the bypass to the condenser. The steam is distributed has an operating pressure of 600 KPa, the temperature of 220C, and the mass flow rate of 49,000 kg/h. This piping system was designed at a pressure of 900 KPa and temperature of 330C. For the design of the path of the main steam piping system (low pressure) using PDMS software. Isometry drawing of PDMS produced to the specifications of the piping system components. Furthermore, the design of the piping system analysis using CAESAR II software. Results for sustain load to code maximum stress 48,575 KPa with 117,900 KPa allowable stress. For loading expansion maximum stress of 82,805 KPa with 273,015 KPa allowable stress. For occasional charging stress to the maximum stress 53,932 KPa with 135,585 KPa allowable stress. From the results obtained stress analysis of piping components experiencing maximum stress that the branching pipe (tee). Component tee with critical stress on sustain loading and occasional analyzed using ANSYS software. The maximum stress intensity obtained on the sustain loading of 167,000 KPa and the occasional load of 175,990 KPa. For vibration analysis obtained by the frequency ratio of 5 lowest mode value is greater than √2, the vibration can be damped and vibrate mode is still safe. From the stress analysis can predict the expansion cycle fatigue failure due to fluctuations in temperature. Expansion of the maximum stress value may reach 671,176 cycles before fatigue.
