Can someone confirm/correct me if I have the following wrong:
I'm using PCC-2, 2022 Edition for reference.
I have a circular insert plate that will have a NPS 10 nozzle in it, the vessel is designed to VIII-1. The insert plate is located on the shell (0.375" thick) and will not be close to any...
I'm working on a project with an end user requirement to include nozzle thrust. I've talked to a few other people and no one has seen a request like this, or is sure how to do it.
As usual, the end user might as well be the Riddler (from Batman). Hopefully someone here is able to help with...
I have a manufactures standard fitting that is attached with a single fillet weld from the outside and meets all the requirements of UW-16(f)(3)(-a)
NPS = 3/4" (ID of 1.05")
OD = 1.438"
Wall = 0.194"
the fitting passes internal pressure requirements, weld sizes, etc.. but fails UG-44...
In NBC-2015, when calculating hn and hx to be used for Ax (height factor), if I have a piece of equipment sitting on the ground outside, only elevated by a skirt, hx and hn are 0, or is hx (elevation on structure) the skirt length, and hn (structure overall height) is the ground to the top of...
Just curious if anyone knows if there is a source that has Figures 2-7.2 , 2-7.3, 2-7.4, 2-7.5, 2-7.6 in table format? I use the long equations in excel, but I'd like to use lookups to reduce space
I'm hoping someone can help me determine the neutral axis and Inertia lx-x of a rolled plate (OD = 30"), but only for a specific angle (42.20981°).
the chord length is 10.6673" at an angel of 42.20981°. I've attached a sketch to make it more clear (I...
I'm making some spreadsheets to do figure 13-2(a), sketch 1. I used the PTB-4 example to do the internal pressure calculations but now I'd like to add the external pressure calculations as well. 13-14(a), no issues, but for 13-14(b), is there a formula for figure 13-14(a), or a chart of the...
I'm trying to calculate the stress ratio per 323.2.2(b)(1) to determine the MDMT reduction in figure 323.2.2B.
per B31.3
(1) circumferential pressure stress for the condition
under consideration (based on minimum pipe wall thickness
less allowances) divided by the basic allowable stress
at the...
I have a vessel with 1.75" thick heads and shell made out of SA-516 70N. The material is impact test exempt (MDMT = -20°F) per fig. UCS-66.1. All the nozzles are HB or LWN made out of SA-350 LF2 Cl.1. 'Everyone' is telling me they always do production impact testing above 1.375" thick material...
I'm looking for a valid way to verify 'Seismic Clip'. The clips are pieces of angle welded to a skirt and bolted to the ground. The skirt on it's own is enough for seismic conditions and I'm thinking that if I do procedure 4-15 from the 4th edition of the Pressure Vessel Design Manual (Moss)...
How do you handle reverse loose flanges with full face gaskets?
I have Compress and it can't do them, but because loose flanges don't take into consideration any of the shell/nozzle or connection, using the Taylor Forger method for a full face loose flange should be the same as a reverse loose...
I'm going through the example problems in API-650 - 2020 edition and for EC.9.4.6, I can't figure out how they go from Xc=23.0 ft to 8,795,200 ft-lb... or Xr for that matter. I get that they are using Ac (convective spectral acceleration parameter), but how does 23ft become 162,874,400?
Xc *...
I'm trying to loop through a table records and fields. The field loops work fine, but I can't get it to move down to the next "tbl" record..
i'm using 3 record sets all based on the same table
tbl = the set I want to loop through
rst1 = loops through table field names and compares against rst2...
I'm grabbing some information from an access table and putting it into word and I'm trying to do the following:
1. Move to tabstop 2
2. insert a string, "Components" in this case
3. move to tabstop 6
4. insert a string, "Material" in this case
the issue is that "Components" varies in length...
is there a way to add a "description" to a section in VBA so that I can reference it when coding? so if I insert a new section I don't have to adjust all my section call outs
currently I'm creating a section from Access VBA to Word like so:
wd.Selection.InsertAfter Text:=vbTab & "TAG...
I'm working on an older vessel that was fabricated from P355NL1 material. I know in the 2019 Edition they removed P355GH, but was P355NL1 ever in II-D, specifically the 1995 Edition.. or if the stress tables were in VIII-1, was it there?
I'm looking to verify the weld in ASME VIII-1 Appendix 2, Figure 2-4(4b). I remember in older code books, I HAD a 1986 book, that the upper flange weld leg was dimensioned as 'c' and the lower weld (outside of pipe) was as it's currently shown, min. = 0.7c.
Looking at Figure (3) & (3a) they...
Hey,
long time viewer as a guest but I've run into something I need a little help with.
I'm trying to do appendix 2 integral flange calculations in excel and I want the long formulas found in Table 2-7.1. I've got them all there and checked, double checked, checked by 2 other people... but I...
