If you have a square "Hot-Rolled Billet" and a square "Hot-Rolled Bar" of the same cross section dimensions, what are the actual differences between the two? Is it a question of length? Does one have more work in it than the other?
I've read those parts as well. I'm trying to understand what the code means by "hot-rolled billet". The definition of a billet is metal in a semi-finished condition and is intended to be further processed (e.g. forged) before being used for a finished product. App 2 states that we can use a...
ASME VIII Division 1 Appendix 2-2(d)(2) states that bar stock may be used to make hubbed flanges as long as the bar stock is "formed into a ring". Does that mean that one can simply drill out the center out of a bar?
We are specifically looking to use hot-rolled bar to manufacture a hubbed...
Flange spacers are sometimes used when there is a need for flange skillets or when there are insufficient spool lengths. Each spacer has two gaskets surfaces on each end. Since the gaskets are in series, the bolt load transferred to each gasket is the full bolt load whether it is one gasket or...
I couldn't find the abaqus_v6.env file in my 2016 installation (it exists in my older installations though) so I made a new one in the current directory with only the code you mentioned. Works perfectly now!
Nevermind on the version thing. I made a test block from scratch and I get the same issue. This block has two solid sections with two materials. Abaqus shows one material when I use:
print session.odbs['Job-1.odb'].sectionCategories
I've attached this simple block in case anyone wants to...
If I manually check the section assignments using:
print session.odbs['Job-1.odb'].rootAssembly.instances['PART-1-1'].sectionAssignments[0].region.elements[0].sectionCategory
print...
I'm trying to extract the material assigned to a particular element (i.e. label # 100). It seems like a very simple command:
elementMaterial = odb.rootAssembly.instances['Part-1'].elements[99].sectionCategory.name
This works flawlessly when the instance has a single section assignment...
In Step 2 of Part 5.3.3.1, it states to get the stresses/strain for "each point" in the component FEA. Does this mean at each node or at each integration point?

What you said makes sense. Combined with Part 3 requirements, essentially all flanges with hub need to meet the requirements of 4.16.4.3.

I submitted interpretation request 16-2209 asking that if by "fabricated flanges with hub" it means "all flanges with hub".
It's essentially Figure 2-4 (6a) just with a 1:3 slope on the hub and a shorter stinger length. No corrosion allowance. I've attached a sketch.http://files.engineering.com/getfile.aspx?folder=198faf49-d3eb-4683-87b5-47d86bc26458&file=Sketch.PNG
SnTMan,
Moving forward that makes sense. I don't see how anyone could tell me I can't do that.
However, this flange is already made. I'm trying to supply the calculations which, in addition to the stress checks, also include the geometry checks.
I'm trying to determine what to take my hub length as per Section VIII - Division 1 - Appendix 2. In this case, my weldneck will have a 1:3 tapered hub that extends down to match the pipe diameter and then continues with a weld stinger, as shown in Figure 2-4 (6a). However, since the tapered hub...
Thanks, jte. Out of curiosity, do you know how the code justifies live loads being neglected during the local check? Based on what I've seen, the live loads are much higher than anything else (specifically sub-sea) thus protection against local fracture strains would be critical during live...
Are the loads excluded from each load combination meant to have a factor of 1 or meant to be excluded altogether? For example, Global Case 1 does not show a factor for live loads. If I have been given live loads as a design input, does that mean Global Case 1 is
2.4*(P + Ps +D) + 0*L
or
2.4*(P...
