Thanks. Thought there might be a small hidden US company someone knew.

Let me clarify, other than a "Goggle Search", which leads to the article that mentions "Nies Formula", Is anyone familar with the Nies information. Thanks

Does anyone know where to locate information regarding ovality calculations by, last name, Nies? Information would be related to steel tires for trunnion mounted rotary equipment. Examples would be a rotary kiln or drum tire. Thanks

Does anyone know of another source for Pressure Vessel Clamps, other then Jaygo?

Is there another good guide for Bin/hopper design? I have the Tubular Steel Structures by Troitsky. The text and the example in Appendix B, Page 7-62 for bunkers has so many typo errors you almost have to re-write the book to follow it. Thanks

Can anyone recommend a good Seismic Design Textbook for Tanks / Pressure Vessels? I need to start at the begining and not with a Handbook. I have both Pressuve Vessel Books, Moss and Megyesy. Thanks

If when you say minimum meaning "least expensive" or "standard CS material", then LWN will be A-105.

Thanks for the comment. For a simple cylinder lift < 20,000 LBS a standard lugs would be acceptable. I was just checking to see if anyone had confirmed the standard lugs using the calculations and notes listed. I have found many of the tables missing back-up information. Everyone references...

The COMPRESS PV Software Manual has a lift lug proceudre in Appendix C, 8 pages. Check their web site.

Several references are made to use the Moss, PVDM 3rd Edition for lug design. I am having trouble confiming/checking/calculating and coming up with the lug thicknesses listed in the Table 7-5 Page 399, based on the loads listed. Has anyone checked this table? Please advise. Thanks

I am looking for the option to include access openings in vessel skirt. Does Compress have this option? Thanks

Thanks Guys, I went back to my mechanics of materials to get a first guess. The expansion length, LE=L*Coef. of Exp* Delta T. The force to compress a column, LE=P*L/(A*E). Set these two equal and solve for P/A. Compare to ASME Allowable. The required weld is based off P.

We have an original design with an 8" XX Heavy 304 SS pipe through a A-105 CS, 1500# blind, 7.25" thick. Operating at 600 F. The weld is not full penetration each ends has 1.5" groove and 7/8" fillet. What would be a good way to evaluate the stress in the pipe between the welds due to the...

In Compress, what is the best type of flange (Slip-On Loose, etc.) and facing sketch(1b right, etc.)to model a 12" NPS standard B16 Slip-on flange? Thanks

kll777: If you are making a repair/replacing a portion of an existing vessel you can replace "like for like". The new rigidity calculations will produce a thicker flange than an original CODE, before 2004 A06. Design using the original code.
