### Temperature Stress Analysis Piping Technology

STRESS THERMAL ANALYSIS. The stress and the thermal analyses are for the most part quite similar. The finite element program Ansys was used for both. There are two main differences between the analyses. Primarily the material properties are different. Young s modulus vs. thermal conductivity for example the other main difference is in
