Fixed Roof Tanks - an overview ScienceDirect Topics.Fixed roofthis is a low-pressure tank with a roof welded to the shell,regardless of roof design or support methods.Double wall storage tank is a tank with an inner wall to contain a liquid (as used in LNG storage tanks),it has an annulus space filled with insulation and an outer wall.cone roof tank - plombier-montfermeil.frThe roof moves up and down inside the tank S-Tank EngineeringOf all the cylindrical tanks,the cone roof tank is the most popular for storing less volatile liquids such as heavy or light oil.STE makes the cone roof tanks in three type:self-supported; frame or truss supported; and column supported.all of our (fuel oil) tanks had the somewhat flat cone-roof (40 ft and larger dia.) -- we had to climb on top to take monthly temperature and levepablo02,Thank you for sharing your feelings and recollections..I hope that your belly has warmed up since those halcion youthful times But yo1MJCronin,I don't have a lot of experience with atmospheric storage but was involved with a project or two some years back. I looked through someEGT01 Thank you for your response..The 60 foot maximum diameter limit (for self-supporting dome roofs) may the the parameter that most influencThis may not be applicable to your case,however,I've generally specified cone or dome type roofs depending on the corrosiveness of the fluid contHi all,further to all the above,I think that the main consideration for the specifying of a cone vs dome roof will be cost. For a given diameterMJCronin,I happened to find another guideline for selection of storage tanks. For what it is worth,Cone roof tanks were indicated for vapor spacIf you are preparing a design/build specification for a tank you must consider what is going on inside the tank when making this decision.
