I need to set up charts which "read" results to use as the X axis and automatically draw the axis to a linear scale, regardless of the values. (Quattro does it but I can't find a route in Excel)
I am attaching a spreadsheet as a sample. Similarly how can I reset the linear axis so that it...
We use galvanized CS wire rope as Guy Ropes to support tall structural stacks. Typically the ropes we use are fully stranded with no core (such as 1 x 37) or may sometimes be fitted with a wire core (6 x 19 IWRC). The quality of the steel is "Improved plow" with a UTS in the region of 220,000...
Whoops
Back in 2003 I published a couple of interactive excel sheets in web pages. Now I find that neither I nor others can access these. Obviously I'm going to have to research what has changed but if anyone has knowledge to direct my search, I'd appreciate it.
Thanks

We are designing vessels (various 12 - 15 ft diameter) which each use a single shell belt of clad plate (mill bonded) which coincides with an internal wet process condition.
Cladding is 0.1 inch x AISI-317L over 7/8" 516-70
The plate, and hence the shell belt will be 8 ft wide.
The internal...
I have a 13ft diameter vessel in A-516-Gr70, which needs a thin 317 SS lining (approx 0.1 ins) in the bottom. The liner will only cover about an 8 ft wide arc and extend roughly 12" above the bottom of the vessel.
There will be nozzle penetrations into the liner. The edges of the nozzles will...
I run Autocad 2004 as part of a package with Inventor and Mech desktop. Recently I got in the mail a trial offer (2 free disks) with Autocad Map 3D, so I loaded it up to see what it was like. As it happens it doesn't do anything for me so I won't be upgrading.
BUT
after I loaded it my AutoCad...
I need to use steel able to resist sour gas attack and I am familiar with the idea of normalizing the (Carbon) steel grain size and controlling the material and weld hardness to minimize the risk of intergranular attack.
"Tempering" was recently thrown around in a discussion and I'm a little...
A client requiring a combustion process provides a mercury (Hg) content as part of the input. If I generate HgO (which I know to be a poison) what do I need to know about down wind glc's.
I normally calculate glc based on Pasquill/Gifford and Briggs plume rise, but HgO will quickly become a...
I need help clarifying an impact test issue
The background:
The design condition for a pipe is -50 degC
We are using A-671 pipe made using A-516 Gr 60, with mill and impact test certs.
The pipe passes through a bulkhead and also has some additional attachments.
The attachments are just guides...
This is one of those times when I think I already know the anwer but someone has shaken me up.. so I'll ask anyway.
My client required impact test to -50 degC (ie: -58 degF). My fabricator already has procedures tested to -65 degF (ie:-53.9 degC) which we submitted to the client (WPS and PQR)...
I presently use ACAD2000 for in-house drawings and send electronic issues as PDF files. Periodically some clients ask for .dwg and I do this reluctantly at the end of the job, with a whole bunch of codicils about the ony "real" drawing being the print which I have on file. When I'm...
Being essentially a Mechanical engineer my Chemistry tends to be very rusty so I need some help please.
On a fairly regular basis I use Heat capacities and Heats of formation in my calcs. When I need to I can look up the requisite values but I do have some rough programming which I put...
I've been using and specifying Guy ropes for structures for a number of years. I generally use bridge strand with a bridge fitting for tensioning.
My preferred attachments to the structure have always been Open Socket fittings which I believed to be wedged with hot, poured zinc.
Recently, I...
I posted a question regarding the difference between Ferrite% and FN at thread288-34135. If you would be kind enough to visit that link for a response I would appreciate your help.
Thanks

We design equipment and have it manufactured in 300 series alloys. With fully austenitic materials, we have traditionally indicated a desire for a weld consumable which would deposit at least 10 percent delta ferrite as a guard against hot cracking, which gave us a lot of problems some years...
Can anyone help with GFRP (fiber glass) please?
I have a need to design a custom fiber glass pressure vessel with our tailored internals.
I'm OK with metals but haven't the first idea how to design with or spec GFRP.
I know that there are strength issues and stress directions to avoid but...
