How to model socket weld pipe fittings in Caesar
Thread Content
In Caesar II, how are socket weld pipe fittings modeled, such as socket weld elbows, socket weld tees, and socket weld branch connections? It’s urgent; I hope experts can provide an answer
This is generally used only in small tubes; chemical pipelines like these do not require analysis. By default, CII uses BW, with a stress increase factor of 1; if it is SW, the stress increase factor is 2.0 or 1.3 (depending on the welding method). Check whether there is an option for this factor in the software settings.
The stress increase factors for pipe fittings such as elbows and tees are likely to be greater than 2.0, so the SW stress index can be disregarded in these areas.
You mean to simulate it just like ordinary butt-welded pipe fittings, right?
It seems that CII handles it in this way, treating it as a butt weld.
Branch pipes in this form are usually small pipelines; a few more bends will suffice. There’s no need to include every type of pipe in the model – use valuable resources where they’re most needed. :)
