Foam chamber mounting on Storage tank

Foam chamber mounting on Storage tank

Foam chamber mounting on Storage tank

Hello to all

I am designing a fire fighting system for hydrocarbons storage facility, in the process of counsulting for foam chambers, I came across a "strange" type of mounting for the latter equipement. The fire fighting equipment supplier proposed for the foam chamber to be mounted directly on the tank shell(without using a nozzle for connection) as shown on the attached figure.

I was wondering whether this type of configuration is permetted on API-650 storage tanks, and if it is, does API-650 give special recommendations for the mentioned case.

looking forward to recieving your responses.

Best regards

We use this vender all the time--- very common fire suppression system.

That's a common arrangement.
I'm not sure if API actually addresses the connection. But it's inherently above the operating level, so it's a zero-stress location.
Note that with the right detailing, you don't need access to the inside of the tank to install it- check on that when detailing out.

I am not surprise with this type of configuration.

I did install this model in some of my previous projects.


RE: Foam chamber mounting on Storage tank

What you show is exceedingly common. Try also looking for "Hollow Point / Tank Battalion" systems. They are also being used a lot.

Thank you for your replies, I understand the concept of this design now :)
