This is an interesting article about how climate change science gets published (or not).
I don't know anything about the Free Press as a source, but the article and its author seems credible to me. You decide.

Interesting video, if you haven't seen it. I haven't found any real info about it. End of life (functional of just economic?) I guess. Anyone seen anything on it?

The problem with sloppy work is that the supply FAR EXCEEDS the demand
Hey Folks, my question is related to language in Sec VIII, Div 1, Apx 13, 13-4(k). This para speaks of moments of inertia calculated on a unit-width basis: I = b*t^3 / 12, with b = 1.0. The direction of dimension b is not formally defined in sketches or nomenclature so far as I know.
Given that...
Working a proposal for replacement of an old S&T exchanger, materials as noted. I've not dealt with this stuff before, so can anyone tell me, in general is this stuff available?
Usual product forms, plate, pipe, forgings, tubes, B16.5 flanges.
TIA,

Referring to 2015 Eds. of Sec VIII, Div 1 & Sec II, Part D:
Table UHA-23 lists both SA-240 and SA-789 of UNS 32101, while Sec II, Part D, Table 1A lists SA-240, but not SA-789.
What gives?
TIA,
Mike

I had a (nearly wasn't) hypothetical situation recently concerning use of reducing tee as a shell eleement. The proposal was to use a 24" X 16" reducing tee as part of a 24" shell w/ 16" nozzle to avoid fabricating the large opening.
Question is: Is the tee inherently adequate without...
Looking for some advice here :)
Supplying two U-tube exchangers exposed to a common process, blowdown at a high temp and pressure. One set of tubes is welded 304, specified to be supplied as solution annealed and meeting ASTM A262, Practice A or E. The other set is seamless alloy 600, N06600...
We don't normally do traditional air coolers, but we've got a couple of replacement designs on our plate now. Not that it matters much to the following, these are design to Code, no stamp, no API 661, no specs, etc. We do not have commercial air cooler design software, nor API 661.
I am curious...
Suspect I "no" the answer, but...
When calling up the Dimension Property Manager to add text such as spacing and so forth to a dimension is there any way to increase the font size in the Dimension Text box? I find it very difficult to read, about as difficult as the text entry box for this...
I am drawing a blank on this, can't find anything from my usual sources.
I am looking for any reproduction of the Kopp & Sayre paper on flanged and flued (thick wall) expansion joints. I've got software to run them, but I don't have anything to tell me what all the different variables mean. Not...
Good day all, see attached screenshot. Why won't the "flange" mirror?

First off, I'm not too good with SW. I'm on 2011 SP0. Don't ask.
I am using a fill pattern to create a large number of holes in a plate. I am getting the idea that SW has no means to tell me how many holes I've got.
I've searched this site (kind of briefly) and find a reference in the SW...
Question for the Shell & Tube folks.
Has anyone ever used some means to protect the O.D. of a packed floating tubesheet (TEMA --W) during insertion of the bundle into the shell?
I'm thinking of maybe some heavy duty heat-shrink film wound around the O.D. or something similiar. Unfortunately...
OK, I am over my head here, but I know I'm in the right place, if not necessarily the right forum:)
We have to buy small quantities of the various product forms of duplex stainless steel, plate, pipe forgings, tubing and fittings. There is a rat's nest of specification requirements covering the...
A supplier is offering SA-790 S31803 (2205) pipe "with no heat treat (HT-0)". This is for Sec VIII, Div 1 use.
SA-790 requires all pipe to be furnished in heat-treated condition.
If using this pipe, the fabricator will be responsible for final heat treat and resulting mechanical properties...
Fellow engineers,
Anybody know of any basis permitting the use of this material for Sec VIII, Div 1 bolting?
Obviously it is not present in Sec II, part D Table 3, as required by Part UNF, UNF-12.
Thanks in advance,

Well, I'm having a bit of disagreement with my software.
Is there any circumstance where it is not permitted or is improper to use the second expression in Fig. UG-37.1 for A1?
The case in question involves opening reinforcement in a flat head when restricting the limits of reinforcement, for...
Well, I have run into a new situation. I am replacing a shell of an older HX, formerly CS and now 2205. MDMT is +51 F. The cylinder is 3/8" thk with some both thinner and thicker parts both welded and bolted on the pressure boundary. Per UHA-51(d)(3)(a), the 3/8" and thinner materials are exempt...
