Re: Pipe thread simulation
Look up the manufacturer pressure ratings of the fittings you are concerned with and stay within those. This is not a good application of finite element analysis.

Re: Pipe thread simulation
Tanks all
You are right . But some times we provide fittings from small market , and they dont have any kind of data sheet . I interested to find out a simulation way for testing .

You may try an axisymmetric, 2D simplification study. The elliptic nature of the threads will be lost, but that's an idealization you may have to make. Your mesh should be extremely fine to capture the stress distribution, and you should model all fillets.

Re: Pipe thread simulation
Isn't this why we have standards? I'm not an expert in pipes but surely there are standardized tests for different pressures and fluids. This seems like a supplier issue, not a design issue.

Re: Pipe thread simulation
Adel,
there is a tutorial installed with the software that explains how to simulate stress in a bolted connection with 2D simplification.

Tanks Alex
It is a big guidance for me . But what i have to do if i want to simulate a real helix thread?

Re: Pipe thread simulation
It will be very complicated and you'll need a lot of experience with non linear analysis.
Here's an example you can take as guidance:

I visit that , but it is not my reply . Is there any way to simulate a helix bolt and not , the example in tutorial is also an axisymmetric .

Re: Pipe thread simulation
If you can't use manufacturer's information you could just model it up and put a pressure on the inside. You'll have to set up contact surfaces between the threads with friction I would think. Should work OK.
