Some type of small fittings are allowed to be attached using fillet weld from one side only, see UW-16(f)

2000psi are 2ksi. Equations 3-F.6 to 3-F.8 are applicable for 13.6ksi ≤ Sa ≤ 870ksi. For Sa values below 13.6ksi (93.7MPa) you are just below the design life curve which result in infinite number of design cycles.

Same issue as here: https://www.eng-tips.com/threads/damage-gt-1-for-low-stress-location-v2017-bpvc-sec-viii-div-2-eqn-3-f-8.476449/#post-8624635 What is the value of Sa?

Looks like the PTB-3 example to me. Why don't you use 2D simplification?

Hello all, I have a SMAW-WPS made based on PQR of A106 Gr.B (P.No.1, Group No.1) I want to use this PQR to weld EN 10025-2 - 1.0045 (S355JR) which is (P.No.1, Group No.2). I know that it this is allowed by ASME IX but I wanted to know if it is allowed by AWS D1.1 & EN 15614. thanks!

Thank you very much @sentrifice That worked!

Hi! Thanks! Unfortunately I am not in Amsterdam for the B31 week

Hello all, I am trying to edit a piping system model in Autopipe. I want to change to orientation of the 3 pipes marked in red. Now, those pipes are parallel to the Y direction, but I want them to be parallel to the Z direction (rotate in 90°) I am new to Autopipe so I guess there is simple...

Have you considered the usage of Code Case 2901? As for the bolt material, we use SA354 Grade BD when need higher strength (steam service)

Note that the Code wording is: "The possible harmful effects of the following design feature shall be evaluated." My understanding is that you shall evaluate the possible effect of the feature that you mentioned, and check how it's effect the design life of the equipment. Keep in mind that when...

Maybe ASME VIII-2, 5.5.2.2 will be suitable for your case. Make sure to evaluate the possible harmful effect of the design feature listed in (a) throguh (f).

What make you think that the method of U-2(g)(1)(-c) is not valid? Note that if Div.2 Part 5 is used, all the failure modes shall be considered, see 46-4(c).

My understaing is that because you do not have a Division 2 vessel, but a Division 1 vessel. For a Division 1 vessel you do not care about 4.1.1.2.1/2 and when no design rules are available you go to U-2(g). This means: When design rules are neither given in Division 1, nor in Part 4 of...

According to ASME Interpretation Number I-81-01: An electric boiler where heat is applied to the boiler pressure vessel externally by electric heating elements, induction coils, or other electrical means is considered to be a fired steam boiler. An electric boiler where the medium (water) is...

Hi, Keep in mind that you do not have a Division 2 vessel, but a Division 1 vessel which needs to be desgin by the design rules of Division 2 (because of the change in Part UHX). That doesn't mean your vessel is a Div. 2 vessel. If there are no design rules in Div. 2 than U-2(g) applies and...
