    Free Vent for API 650 Tank - Bug Screen / Bird Screen Requirement

    I am a fan of API 650, but for water tanks perhaps these might help: NFPA-22 "NFPA 22, Standard for Water Tanks for Private Fire Protection" AWWA D-100 "Welded Carbon Steel Tanks for Water Storage" From a fairly old edition of NFPA-22: 4.14.2 A vent pipe shall have a cross-sectional area equal...

    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

    I tried copy the objects, see attached - it did not remove the bad plot style from the text 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...

    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

    I have a few drawings that do not print some dimensions correctly. I print to PDF using styles, all layers and objects use a style called Style 1 that uses Monochrome.stb The dimensions are on the layer Dims whose plotstyle is set for Style 1 The dimensions are on the correct layer, properties...
