A water hammer is a hydraulic shock that occurs in a piping system when a fluid (usually water) is suddenly stopped or forced to change direction. This sudden change in the fluid's momentum can...

CAESAR II vs START-PROF Piping Stress Analysis Software Comparison
In this article, we will compare START-PROF and Caesar II functions. In START-PROF all pipes, fittings, and nodes are objects. Each object has its properties. For example, you can place bend objects...
How to use ASME B31J and FEM for SIF and k-factors for Stress Analysis
How to use ASME B31J SIF and k-factors in PASS/START-PROF For a long time, there was a need for a standard method to develop stress intensification factors (SIFs or i-factors) for ASME piping...
What if Piping Continuation is Unknown? Part 2. Underground Piping
Continued from Part 1 What if Underground Piping Continuation is Unknown? It is necessary to specify the correct boundary conditions while modeling main pipeline stations: valve station, pig...
Start-Prof can estimate the support loads and stresses caused by relief valve discharge by an equivalent static method. The relief valve discharge thrust load acts on elbow 28. In Start-Prof it...
Modeling Fired Heater Piping Connection is a bit tricky as the pipe is not welded to a fired heater shell similar to ordinary equipment. The heater has a hole, the pipe runs through that hole inside...
