r6155, thank you for pointing me to the PIP VEFV1106 (which is part of document VEFV1100, if you are trying to find it on IHS or PIP website). VEFV1105 shows details for Horizontal Vessel Saddles Supported on Concrete and VEFV1106 shows details for Horizontal Vessel Saddles Supported on...
I fully understand the pressure classes that are used for flanged valves (per ASME B16.5: Class 150, 300, 600, 900, 1500, 2500). It makes a ton of sense to me. You have a pressure and temperature of the piping system, you go to ASME B16.5, you look up the pressure class corresponding to the...
Thank you all very much for your responses. After more research that was encouraged and inspired by your responses, I am becoming more familiar with the documents that contain industry guidance/requirements for end connections including threading and welding. Perhaps my question was asked out...
Thank you all for the guidance. It really is unfortunate that there is not an authoritative document on this issue that could be used to standardize processing plants/equipment. At the very least, it would make the meetings I am involved in on this topic much shorter. All the best!
I guess I was hoping that there would be a specification that gave guidance with regard to when (or if) threads are ever inappropriate to use. Am I right to interpret B31.3 that threads are appropriate to use in all temperatures and pressures?
With all of the varying opinions on this board...

I am starting this thread to ask for some guidance after reading another thread: http://www.eng-tips.com/viewthread.cfm?qid=358123
I fully understand that there are differing *opinions* on when it is appropriate and/or cost-effective to use threaded connections or socket...
Thank you, all. Good discussion.
Support design is part of our drawing review process with our vendor's drawings. The disagreement was internally with a colleague as to whether I should be requesting center or edge webs in our supports and what the cost implications were, if any.
Yes, my...
My company often deals with placing vessels on skids (steel structure) instead of on concrete pads. Since our supporting steel (skid) is constructed of I-beams, my opinion is that we also ought to have vessel support saddles with a corresponding I-beam sections (web of the saddle centered)...
Thanks, all, for your responses. I haven't had much of a chance to read them today, but will read them in detail after the holiday weekend. I very much appreciate your input.
All the best to you in this New Year!
Let me preface this by saying that I am fairly uninformed in this industry as I previously was an engineer in a different industry. I have not had much luck in finding industry standard approaches on some of these issues, and my company doesn't have very good internal documents/standards, so I...
