Emergency vent on FRP tank

Emergency vent on FRP tank

Emergency vent on FRP tank

(OP)
I have ATM Fiberglass tank. I was wondeing if I need to provide Emergency vent for Fire case on Fiberglass tnak.

Your insight/thoughts are welcome.
 

RE: Emergency vent on FRP tank

The pressure relief requirements are the same for Fiberglass and metal.
If a pool fire is credible, an emergency vent for Fire would be required.
If you have good drainage or no combustibles in the vacinity
or no exposure from adjacent tanks, a Fire contingency may not be credible.  

RE: Emergency vent on FRP tank

The major tank vent manufacturers make FRP vents as well.  Try Protectoseal, Groth.

RE: Emergency vent on FRP tank

UUuuummmmmm....... i could be wrong.....but,

I understand emergency pressure relief for a "fire case" as required when there is a pool fire and pressure builds due to external heating of the vessel.

But this cannot occur for a fiberglass tank ?

How does the tank survive the fire long enough to actuate the relief device ?

NFPA-30 requires metallic tanks to contain flammable and combustable liquids.

   

RE: Emergency vent on FRP tank

Just size, fabricate and install a "gooseneck" vent for it.

Good luck,

I have 5 SS and 1 FRP tank, and all of them are sharing common dike. All the tanks are indoor and materials are non flammable.

All the tanks have conservative vent designed for pump in/out and thermal effect. It is not designed for emergency vent.

I was planning to provide Emergency vent on all the SS tanks in case of external fire. However, I am not sure if FRP tank would require emergency vent. I thought that FRP tank will rupture at high temperature for external fire and emergency vent is not required.

Is my understading correct?

 

RE: Emergency vent on FRP tank

Even I think that FRP tank will rupture at high temperature for external fire and hence an emergency vent is not required.

I think you should designed the vent for Pump IN/OUT and Breathing Losses.

As for SS tanks you can refer API-2000 for sizing the Vents
