Simulation and stress verification in CAESAR II of square-to-round transitions, variable-diameter square tubes, and square ends of equipment in pipelines
Thread Content
Lu Gong: Hello! As mentioned in the title, it deals with the simulation and stress verification in CAESAR II of square-to-round transitions in pipes, square tubes with varying diameters, and the square ends of equipment. I remember asking you about it, but I didn’t understand it at the time and didn’t delve into it further; to this day I still don’t know how to solve it. Could you explain it in detail? I’m not sure if this way of phrasing clarifies my question; please advise. Lin Gong
Rectangular cross-sections do not have as good pressure-bearing capacity as circular cross-sections; therefore, circular cross-sections are more suitable for use in pressure pipelines； Rectangles and the concept of a round sky and square earth are both used in smoke and air ducts, with pressures generally staying within the range of +/-30 kPa
Yes, but sometimes it’s necessary to check the stress on the pipe ends; I want to know how to calculate it
Pipeline stress calculation software is all based on circular cross-sections; for rectangular ones, finite element software is required
It cannot be calculated using C2, as C2 is a unit for beams; you can use finite element analysis methods such as ANSYS
