Good morning all, I have done a bunch of searching on the forum and have not found a thread that directly aids in solving my issue. I did find this thread that was really close, and I have based my understanding of the correct methodology on it and the ASME interpretation included...

Good morning all, I am putting together a comprehensive pipe thickness excel tool. Piping codes included: B31.3, B31.4, B31.8, 49 CFR 192, 49 CFR 195. I am struggling a little bit with the differences in required thickness. B31.3 is very clear, and specifies that minimum thickness (T) must be...

rb, There definitely is a relationship between E, nu, G but I only have one of the three values. E= (2*G)(1+nu) I do not have a value for nu or G. The information I listed is the extent of the information that I was given. I have found the same thing about directional properties. Thank you...

Yes sir this is a chopped fiber. Strands will be between 2" and 3" long.

Thanks for the replies guys! Ed I feared that was the best option to truly understand the material properties. I was wondering if there was any way to manipulate the information that I have to fill in missing material properties. I think I will follow this path. rb your explanation makes...

Good morning all, I have been asked by a subdivision of our company to structural integrity of a fiberglass building during a loading condition (picking up a motor with a chain hoist mounted to the roof). My understanding of composites needs work. I will be running an FEA simulation using...

It is 3 feet, sorry about that. Compress Error: Operating Hot & New Seismic Compressive (governing): 4.5.17: Opening diameter (12in) is greater than 25% of the Support Skirt diameter (0.25*47.5 = 11.875)

Description of problem: We have a 48" OD vessel with a 48" OD skirt. The skirt is 0.25" thick (only 0.0216" thickness required) and just under 3" tall with no base ring. The drain on the vessel is a flanged T connection and must exit the skirt at opposite sides. The maximum opening I can put in...

TGS4, We are a Div 1 shop and do not have copies of Div 2. Can you share a portion of it with me or a link to where I could view this portion of the code? You are saying that the FEA will not be adequate as it violates the requirement set in Div 2, correct? AND analyzing the nozzle as a solid...

Compress does use NozzlePro and I plan to use it to prove these nozzles. I would guess that you did not create these calculations, but do you have any idea why the heavier nozzles are not covered in WRC 537 or 107? Is it assumed that they will see lower stress, so it is safe to assume the...

I would imagine almost all, if not all of the HB and up nozzles will be outside of the range for gamma. Is there another method other than WRC 537 to check these nozzles?

Thank you very much SnTMan. I am contacting my customer right now.

Good afternoon, I have used Compress to model a vessel and the applied external loads to nozzles. All of my nozzles meet limits of reinforcement. When I run calculations, I get deficiencies on 3 nozzles. Each of these nozzles are in a head of the vessel. The deficiency says, "Load case 1: WRC...
