Not sure if this answers your questions (or if I understand you correctly), but AutoPIPE takes the input for seismic that you provide it with, regardless who supplied you with that input. For ASCE 7, you can enter the ZIP/Postal code (provided the location your pipe stress model will be situated...

Appendix O has some default torque values, but not for your situation (RTJ). Whats the size and flange material? What K-factor do you expect? A bit off-topic here, hopefully someone more knowledgeable on BFJ's and PCC-1 isreading along; how does one determine the appropriate Appendix O factor...

Normally, c is a given value. Based on formatting, if yellow is input, c is a given value in advance. Refer to 304.1.1 how c is determined. If the pipe requires 12/5% tolerance on wt, you already have a c of 0.0469 in. I would ask the engineer who made this calc, how he ended up with 0.059 in...

Torque is dependent on a lot of things, which yo haven't specified — for example, not only flange size, but also flange material, gasket material, anti-seize, etc. One crucial aspect is knowing/understanding the nut factor. In the end, the gasket stress is what matters, and that's achieved by...

Does this project require conformity to EN 1090, or do the products fall under the scope of CPR 305/2011? Then, im afraid CE-mark is an absolute legal requirement. We’ve had our Canadian sister company (who are familiar with the North American market) do a CE-marked project for the EU market...

Correct, but this a weldolet. Weldolets are also used on elbows, in the configuration shown above. Does the Code allow this practice? No, I think not. The elbow is likely considered an unlisted fitting now. Is this method used more often for Code applications, without further/additional...

I dont think it directly answers the OP's question, but there's been more discussion recently here at ET on B31E vs B31x; https://www.eng-tips.com/viewthread.cfm?qid=521690. I think if you understand the differences in both Codes, you might find an answer more easily. Huub - You never get what...

Thanks guys for the valuable feedback. Huub - You never get what you expect, you only get what you inspect.

I have the following, similar issue. Im curious to hear others opinion. Construction code: B31.3 2022 Piping MoC: DSS 2205 Fluid service involves chlorides Client has no specs or specific requirements for this piping scope Piping requires bends with a larger radius than default B16.9 LR...

I'm not much into welding engineering, but I recall that ER309 shouldn't be used for such DMW if the application runs at high temperatures. Huub - You never get what you expect, you only get what you inspect.

As to your specific question: I will not answer that (perhaps someone else can). If youre interested in understanding the Code change process, its a good idea to attend Code committee meeting. They're free. There are all sorts of committees you can join. I can only tell from personal...

Welcome to eng-tips. I hope you'll enjoy your stay here and that we can learn from each other's experience and knowledge! Afaik, there is none. The European counterpart for piping (EN 13480) is much more prescriptive then ASME B31.3, when it comes to all sorts of design rules, formulae...

What’s the metal temperature of the shell and jacket, approximately? They have different CTEs which also can be a real cause of additional stress Huub - You never get what you expect, you only get what you inspect.

More details are needed. But Ill give it a shot (Im not an expert by any means in this stuff). It appears you have inward buckling - external pressure issue? Is the shell sufficiently strong for the coincidental case of 2 bar(g) on the jacket, and perhaps a low pressure (or even vacuum) on...

A403 is a standard for individual items: fittings. B31.3 is a Code for piping, i.e. assemblies of pipe, fittings, flanges etc. It’s apples and bananas. You’re confusing the two Huub - You never get what you expect, you only get what you inspect.

Such question is better asked internally in your company to your mentor. How can you defend a situation where, for a stress critical item, the calculation was verified on the internet by an unknown person? Also, bear in mind people here are willing to help with specific questions, but this is...

Thanks weldstan. Do you happen to know an equivalent European grade? Would that be 13CrMo4-5? Huub - You never get what you expect, you only get what you inspect.

If this is real 316L, you have an issue, as that grade is limited to below 500 deg C in most codes. Straight 316 may give you some slack, but as 1503-44 mentioned, not much. 316H is better, and I think also required in most - if not all - ASME codes, due to the minimum required carbon content...

I've never worked with applications using carbon and low alloy (CS&LA) steels above 400-425 deg C (where one would stop using default CS gardes likes A106-B). Just out of curiosity, if I need an LA for use above 450 °C (say 500 °C), would P11 be a good starting point from a...

It depends on your code of construction (e.g., B31.3 or BPV VIII-1) and design conditions. If you share those, perhaps you'll get a better answer, but it's also recommended that you first check the codes yourself to find an answer. Anyone here can help you determine the answer, but you'll be...
