Could anyone tell me when is recommeded subsurface foam injection in vertical storage tank for fire fighting?.
What kind of product need, for fire fighting, subsurface foam injection?.
For fuel Storage tanks fire protection I have the following questions:
1.- When sub surface foam inyection system is recommended?.
2.- Best Inyection foam system for Diesel & Jet A1 (sub surface or surface inyection).
3.- Application rate of foam for Diesel, Jet A1, HFO (Heavy Fuel Oil) &...

Is There any trouble in having lap weld bottom joints?. Why?
Does anyone can tell me the criteria to evaluate if the tank roof and shell are designed to contain the sloshing liquid?
By the other hand I would like to know what happen if the sloshing height is bigger that the freeboard.

In a cone roof supported tank with an internal design pressure bigger than the roof plate weight. Can I weld the roof plate to the structrure?
I have a custome who want to use 8" pipe to flow 2,925 us gpm. In this case the flow velocity es aproximatelly 18.78 fps.
Is this velocity aceptable?
NFPA hava a maximum velocity limits in branches pipes for foam solution and spray water system (cooling water for vertical storage tanks)?
