Ok, so g1 is the throat thickness * √2 ?

Hallo! What does g1 and g2 represent in EN13445-3 table A-7 figure F4 ? Could it have something to do with the throat thickness of the fillet welds? Thanks!

I am trying to understand the tri-axial stress state in steel welded structures and pressure vessels, etc. When does this phenomena occur - i.e. when should i be cautious doing a stress analysis (in ansys mechanical)? How should i check for this effect in ansys mechanical? EN13445-3 Annex C...

Thank you, appreciate the input.

Suppose I have a 1'' schedule 80 pipe with a corrosion allowance (CA) of 0.126'', factoring in a 12.5% mill tolerance and using A106GrB, which leaves me with a remaining thickness of 0.0224''. While this thickness is acceptable from a pressure standpoint, I am concerned about the structural...

Thank you for the response, I have the data set in the link below. What is the correct way to determine a lower scatter band representing a 95% confidence level? Is there a certain method that is used to determine creep values, or is it sufficient to do a spline and then determine a standard...

Hi all, How do i determine a larson-miller regression line based on raw creep data (time, temp, stress)? The material doesnt exist in the standards. I assume i could do a spline based of the data? I guess what i am looking for is a larson-miller parameter calculator, but i am certain i am...

This vessel has already been built, so it is not possible to pick another material, unfortunately.

Thank you for the explanation, Is 3 h enough time for SS 304L to start creeping? Can i extrapolate the values from the elastic allowable stress from API 530 Addendum for SS 304L at 816C up to 900C? The Elastic allowable stress from API 530 Addendum Table E.11 SS 304/304H @ 816C = 83.1 MPa...

Thanks for the reply, but im not sure i follow. How long did you test for? What does RT 85/37 mean? Please explain these numbers for a layman :)

What is the yield and tensile strength of stainless steel SA-240 304L (S30403) at 900 C for a duration of < 3 hours? It is a pressure vessel subjected to a fire.
