Hello,

I have 45deg forged tee component. In Caesar II, I model as 45 connection with welding tee type. Then import the file into FEATools and press convert button.

Can FEATools (module B31J or FEA) understand the 45deg forged tee component? Or any additional input need to be specified in FEATools?

Any reply is appreciate

While NozzlePro has the ability to calculate sifs and flexibilities for laterals, I do not know whether or not FEATools, which uses NozzlePro and automates the input process, uses the relative pipe angles as input.

If you have FEATools, you likely also have NozzlePro. I would suggest calculating via NozzlePro and then validating between the two.

If using NoozlePro, what type of nozzle shall be used to define forge component (straight, pad, barrel) ?

Typically, we do not have the geometry information to make a realistic answer, thus we must be conservative, and therefore, I would personally use straight and pipe-to-pipe intersection.

You might consider a small weld size to reduce the effect of the discontinuity, but not so large that the physical component provided will have a smaller wall at the intersection.

Just my personal opinion...

That 45 deg forged tee is it a Latrolet, actually?
If yes, I would definitely use Caesar II Latrolet SIFs from CII internal database. They are established as per Bonney Forge reference data, and Bonney Forge is a well-known and reputed international manufacturer.

In this way, speculations are avoided and I believe SIFs values are realistic enough.

In general, as pointed out above, the actual geometry of the fitting is un-known. Any FEA model would mean to speculate, more or less conservatively.

If the Client/Owner is not happy with such approach, ask him to indicate what approximate skewed intersection to assume for FEA assessment, but warn him/her that an un-reinforced intersection might be excessively conservative and might yield to high stresses and consequently high demands for layout flexibility and maybe sophisticated support arrangement.
