    DOUBLE DECK FLOATING ROOF DETAILS

    Thanks a lot. Excellent information. What I did is just make a calculation (spreadsheet) trying to estimate desck separation (roof hieght) in order to verify bouyancy (Total weight / Total volumen <= 0.7 x 62.4 lb/cu.feet). I've compare results with estimated weight on your informatión (300'...

    DOUBLE DECK FLOATING ROOF DETAILS

    Thanks for your attention. Well, actually what I need is more theory (basis, fundamentals, principies, best practices, tipical geometry, etc.) that let me make a preliminar design (dimensioning). However, It doesn't matter roof diameter ? If volume equivalent to this 5" under liquid is...

    DOUBLE DECK FLOATING ROOF DETAILS

    Well, It seems I'm not the only one looking for details 'bout DDFR. I've "figured out" some information on: www.cbiepc.com/cbi/products/floating-rooftanks_design.html It's just general information, So if someone of you just have more detailed informatión (I mean drawing, basis for design &...

    Piping Specs for High Pressure Gas Injection

    Hi, thanks for your interest. Pipeline estimated size is 12.75 OD. Thickness will depend on which one code is gonna be used. What do you think ?

    Piping Vibration Level Guidelines

    Try ISA codes involving design and specs of control valves. Vibration and noise in such elements couild thread pipe integrity. Right I've got a couple of projects due to excesive vibration and noise in piping systems. Verufy SPL (Sound Power Levels) and feed your stress analysis software with...

    Piping Specs for High Pressure Gas Injection

    Hi. May be someone has got experience about this case...I hope so...! My question: Should I design by ASME/ANSI B31.3 or ASME/ANSI B31.8 in a High Pressure Gas Injection pipeline (Design Pressure = 9000 PSIA / Length = 12 Km) ?
