We use Algor PipePlus to analyze piping to meet ASMEB31.3. The software allows the user to include or exclude pressure thrust in the alaysis. If there are no bellows in a piping system, should pressure thrust be included in the analysis? If pressure thrust is included, the analysis results show large piping displacements and it is very difficult to get stresses within Code limits. I have modeled existing piping systems in our plant, including pressure thrust in the analysis, and found that the actual piping displacements are much less than the calculated displacements. I can not find anything in the B31.3 code that says that pressure thrust should be included if there is no expansion joint in a piping system. Any help?
