    Storage tank ?pressure dome? - just curious

    HTURKAK - Since the tank was fitted with API 50 Annex H shell vents, only one center vent on top of the dome would be needed.

    Storage tank ?pressure dome? - just curious

    I can't find pictures of exactly this type of tank but check out https://www.mesaetp.com/tank-products/vapor-bladders/ The picture show a regular cone roof tank with a vapor bladder being installed sort of half way up the tank shell. When the bladder is in the up position it presses against the...

    Storage tank ?pressure dome? - just curious

    It is ecactly as Geoff13 wrote. Before the circulation vents were added, it was a closed tank with a dome shaped membrane attached to the fixed roof where the dome attaches. The shell vents converted it to a freely vented tank, the membrane removed but the dome left there for cost reasons.

    Ugly Plot Style names

    Yes, I'm using Bricscad, having gotten tired of Autodesk's licensing scheme. I'll try the copy method in the latest version of Bricscad and see if that helps. Thanks for your efforts!!!

    Ugly Plot Style names

    ...in the dimension. The text still prints in color and the telltale is that when you explode the dimension the text plotstyle for the text is FR LAD* no matter what plot style the unexploded dimension uses. Can you confirm the telltale above or send send a file that has the copied dimensions...

    Ugly Plot Style names

    Attached is a DWG inside a Zip file Plot preview to Adobe and you'll see the dim text is blue. It looks right but if you explode the dimension you can see that the plotstyle of the text is wrong. I can make it work by changing the layer color to 7 but I'd rather make it right and get rid of the...

    Ugly Plot Style names

    I will try that, thanks! I'd really like to find a command or macro that would allow the deletion of a missing plotstyle while replacing it with one that is not missing. Or a command / macro that re-assigns plotstyles to entities, that works for nested ones like a dimension. Chprop (select)...

    Ugly Plot Style names

    ...This should be easy to fix - just make the new styles. When I explode these dimensoins I find that the text is associated with a plot style "th as*" The "*" is an illegal character so I can't make a new plot style with that name. If it were one dimension, easy - just delete and make a new...

    Installation manuel

    The installation processs is very different between aluminum full- and non- contact IFRs. Are you interested in which part gets installed first, or more general question of should you buy a full- or non- contact IR?

    API 650 Tank Rebuild - Type and quantity of weld inspections

    Are you going to perform a hydrotest per API 650? If you are electing to not do hydrotest API requires additional NDE and foundation capacity. You may want to require additonal NDE if a tank failure is a high risk to the public, if your local conditions or lack of confidence in quality...

    API 650 - Tank stiffening ring calculations

    You have to satisfy all sections of API 650 that apply to your tank, and all load cases. If section 5.9 is satisfied without additional stiffeners you have complied with that section. If you are designing an Annex V tank then you need to satisfy that Annex. If your tank needed stiffeners per...
