    Continuous Rings with Support Lugs

    When the continuous rings for support lugs box is checked what is the assumption for the width of these rings? Is the ring on bottom the same width/thickness as the top plate/ring? The graphic depiction shows the bottom ring at the full width of the bottom plate. Is this truly the case? Why...

    Quick Access Toolbar Missing - How to bring it back?

    Got a new computer and loaded AutoCAD 2009 and now the "Quick Access Toolbar" is missing and I cannot find a place to turn it on or bring it back. I'm sure it is something simple. The "Quick Access Toolbar" is supposed to be right next to the big red "A" on the upper left of the screen...

    Lifting Lug Analysis

    Previously you could put (4) lugs on a horizontal vessel...now it won't allow you more than (2). Why the change from allowing multiple lugs to now only allowing (2)? Thanks.

    Head Straight Flange Thickness

    In designing the same vessel using several different PV softwares a question has arose. Compress is designing the head straight flange using the total design length. It is just a small piece and it is attached to the head. So, the head will provide support. If you consider the analogy of a...

    Latest Update 6253 margins all screwed up for printing

    I know you already know that there are issues, but it is not just the left margin but ALL of them are messed up when you try to print. http://www.codeware.com/support/faq/1201.html This is extremely annoying and inconvenient and I hope it is resolved soon. Brian

    Vacuum Stiffener Rings

    The "rings" only take flat bar common sizes, thus the size I wish to use to utilize drop from the shell plate is not available. I know it works as I've done other calculations to support the different rings, but the customer wants to see it in COMPRESS. I tried the "user defined" category...

    ECCS Formula-never seen this one before

    From COMPRESS: Pressure during the shop hydro test exceeds 90% of the head plastic buckling pressure = ???? psi. The minimum thickness recommended by the ECCS formula = 0.???? in. I found one thread on the ECCS formula but not much else. Can someone provide me a reference or link? Thanks. Brian

    Lifting Lugs/Trunnions on Jacketed Pressure Vessel

    Never had an occasion to think about it before, but one has presented itself where the lifting lugs, probably trunnions due to a bolted connection top (vertical vessel), will have to be placed on the jacketed portion of a vessel. It is only jacketed at the top and goes too far down to make...

    "Forged flanges are only available for nozzle types 9 and 10"

    I have just noticed this message appearing in the flange dialogue box no matter what nozzle type I have selected (usually 1-4) or what type flange or flange material I select. Doesn't seem right. Brian

    "Rigging"???

    Trying to find out how to turn this option "off" as far as just doing some general calculation for bid purposes. It keeps showing up in the printout listing (even if it is just a blank page) but never in the listing before printing. What is going on? I've never noticed it before and I can't...

    Upcoming Seminars in Houston in October

    I use COMPRESS everyday and it has been a "learn by doing" process over the years. I was wondering if any of the 3 seminars you are offering in October in Houston would be truly beneficial to someone who is not new to COMPRESS, even the "training" one on just COMPRESS. I've been to some...

    Reducing Flange Ratings

    2" s.s. nozzle in shell designed for 150 psig @ 400F jacketed by a 3" c.s. nozzle designed for 260 psig @ 450F I can't find anything in ASME Sect XIII Div 1 that addresses this specifically => What tells me the reducing flange has to be rated to withstand the jacketing nozzle pressure and temp...

    Separating air compressors and tanks?

    This is a tangent from the used fire extinguisher air tank (bomb) thread I started. I'd really like to find out more information about separating air compressors and their tanks. Several folks mentioned studies and projects in the other thread, but I was unsure if there was anything...

    Using an out of service fire extinguisher as an air tank

    I'm trying to discourage someone doing such as a "bad idea" and would like to hear your thoughts. 1. Typical red 3 gallon fire extinguisher is one that has been taken out of service due to time limits 2. Top nozzle has been replaced by a welding in a coupling 3. Mounting tabs welded onto shell...

    Skirt to Base Ring Weld

    Good morning. Typically, we use a standardized detail that makes the fillet welds (inside and out) the same thickness as the skirt, on the skirt to base ring connection. However, due to bolt circle limitations (just not enough room for such a huge fillet weld and get the nuts on there) and a...

    FE/PE Exam Advice

    I've read numerous threads/posts on the subject and perhaps even started a similar one before...but I was wondering just how hard it would be for me to obtain my PE. I am soon to be 37 years old, wife, two pre-school boys and generally work a 50 hour work week, sometimes more, sometimes less...
