For fittings, EN 13480 relies on EN 10253. That standard has two types of design for each fitting; type A and B. Type A has a pressure resting that’s less than an equivalent sized seamless pipe rating. The derating is quite complex, or at least not straight forward. Type B has the same rating as...
Luka, Im the EU as well, and given the businesses we work for, we have a lot of similarities. But Id suggest you to not - ever - go for a TC with these dimensions and pressures ever again. You've been given sound (and free!) advice form LI and ES here, and take that for granted. I get the...
Interesting question. (Im Dutch as well and we also often stumble on some of the nasty quirks and shortcomings of working with EN 13480). Apart from the previous advices given, what you could also is show that the 'B31.3' equivalent strength (or call it pressure rating) meets the EN 13480...
There’s some literature on this subject. I’m not familiar with these applications though I have done some high temp jobs (with lower pressures) using some of these alloys. From what I’ve read 740/740H is mentioned frequently said to be the next best candidate, along with 617. Their resistance to...
Hi Idan. I’m happy to show/help you but it’s a bit difficult through a forum. AutoPIPE is a bit quirky with these kind of things at first but once you get the hang of it, it’s a quite good I think. Their (online) forum and help are also quite good. Are you in Amsterdam by any chance this week...
You keep on saying and saying this r, not only in this post, but also several other posts. Yet, you never provide a decent argument. When questioned, you mention you're not a tutor. That may be true, but nog giving answers means you don't seem to be competent either.
There are plenty good...
We’ve had similar applications, though we would make sure the machining is done first. Good point from TGS4, given the size certain inspections are very difficult.
Do a complete PT on the inside. That’s how we found an issue in the past (though we had a cladded inside where the clad layer...
Id have to disagree, that's incorrect. The PED doesn't 'recognize' codes. There are harmonized standards however, like EN 13480, that fulfill and meet all PED requirements if such design code is applied in full. In those cases, no additional work is required during the conformity assessment to...
Your construction code (which you haven't specified, such as B31.3 or VIII-1) may set additional, more stringent requirements on top of ASME IX. Take those into consideration as well.
r, please provide some technical basis or background for your side of the story.
So far its the old song going on all bolt torque threads where you comment on: you mention elongation should be used, but never provide a reasonable or viable argument for your side of the story. Please do that...
This made me think; where has Pats pub gone to? Where are the non-engineering off topic (political) discussions done now at ET? I can’t find them anymore!
That's my understanding too, but r6155 keeps on coming with the same reply over and over in each thread about bolting, torque, etc. His posts are usually too short to truly understand his reasoning. I sincerely hope that, based on the feedback in this thread, he can provide arguments for his...
Exactly my thought. @Pavan: I haven't run your calcs, but you need to neglect the time-dependent allowable stress. Determining f is an easy task, and then plugging it in the equation to find your answer should be easy as well.
Look at the other, same thread, in which I provided you more...
This is one of the reasons I try to stay away from EN 13445 for creep applications.
Bet lets give it a shot, Im happy to learn from others regarding creep design in Eurocodes
Wouldnt that be defined in Chapter 19?
Chapter 19 relates to Annex M as well. That may answers your question(s).
Im...
Hey there Pavan.
I would suggest you start using the current version of EN 13480-3, which is the 2024 edt.
That being said, the rules allowable for determining allowable stresses are in part 3, section 5.2. Specifically 5.2.1.
The input values for yield, tensile etc are in the product...
