My experience has been:
The foam chamber flanged nozzles were considered in the original design and were therefore included by the tank fabricator. Supporting locations for the foam piping was also supposed to be considered in a new tank.
Foam chambers are installed outside of the shell
The foaming devices, attached to the nozzles, the foam piping and any and all components required to make a complete system is the responsibility of the Fire Protection contractor
How about the heat detection devices located within the tank ? .... Have these been considered ?
Installation of heat detection devices would require interior scaffolding ..... IMHO
