<div>Piping system failure can be caused by several factors, one of which is
the pipe load. Pipe loads cause stress to the pipe. The thickness of the
pipe in the piping system affects the value of the stress. The research
uses the computational method of pipe stress analysis by comparing the
value of stress in the variation of schedule pipe thickness 10S 4mm;
schedule 80 13mm; and the XXS 22mm schedule between manual calculations
and the results of a simulation of pipe stress analysis. The purpose of
this research is to find out the value of stress to temperature of 500o
F and pressure of 689 KPa from the results of manual calculations with
the calculation results of pipe stress analysis to compare with the
value of the allowable stress limit on N08825 nickel alloy material of
241.31 MPa. Pipe stress analysis is needed to calculate the amount of
stress caused by the load on the pipe. Loading is carried out at a
temperature of 500o F and a pressure of 689 KPa. Research on variations
in pipe thickness produces a value of 18.86 MPa for each manual
calculation, 30.6 MPa for CAESAR II and 41.75 MPa for ANSYS calculations</div>
