ASME Div. 3 ???

[blacksmith37]

Been retired awhile; I recently went to a dinner meeting where the speaker often referred to ASME Div 3 : Is there one ?
I suspect he meant Section 3.

 

[XL83NL]

Or Sect VIII Div 3

 

[SnTMan]

Sec VIII Div 3 added a few years back (like 10?) for high pressure vessels.

Regards,

Mike

Typically applies for design, construction, inspection, and overpressure protection of metallic pressure vessels with design pressures typically above 10 ksi (70 MPa).This is relative new edition under ASME Sec-VIII. Usually fabricators with extensive fabrication experience in DIV-2 vessels would be more comfortable with this code than the others.

If he meant Section III, he was referring to the Nuclear Code. Was he??

I hate to be obsolete. He was referring to sophisticated stress analysis including fatigue; that's what made me think of the Section 3 nuke.
Thanks for the update.

Blacksmith37 - the VIII-3 stress analyses are state of the art, and the fatigue analysis is usually a cycle-by-cycle fracture mechnics assessment. These vessels need to positively demonstrate leak-before-break, among other things. They usually use very high strength materials, including very high yield-to-tensile ratio materials. Also, they can use composite outer windings to add additional strength. And they often use techniques such as autofrettage to improve fatigue performance.

Although this Division is typically used for internal pressures exceeding 10ksi, I have seen pressures as high as 80-90ksi (think large-bore naval gun barrels...).

blacksmith37,
Based on your last comment, I suspect that he was referring to design per Section VIII, Div.3.
