Is it appropriate to install pipe rack structures inside the fire dike of Class A and B storage tanks?

As the title suggests, is it appropriate to install a pipe rack within the fire dike of Class A and B liquid storage tanks? Are there any standards available for reference? Let’s discuss! Thank you!
Of course. The utility tunnels all have to pass through the tank farm; however, the tunnels in the tank farm are usually quite low in height, and they are called pipe piers
Generally speaking, there are pipe corridors in the irrigation area, as the materials within it need to enter or come out of the equipment. However, it is not possible to deliberately design pipe racks for unrelated materials to enter and exit the storage tanks. This will increase the risk.
Without utility tunnels, how can the pipes be laid?
Back then, for a project, the pipeline gallery for the basic design of the tank farm was located inside the tank farm itself. When I took over to work on the detailed construction drawings, experts said they had never seen a pipeline gallery placed inside a tank farm, and they also mentioned that it would affect firefighting capabilities. So the gallery had to be removed, and all the piping had to be redone; to this day I still can’t understand why that was necessary. Personally, I think that if a pipe gallery is necessary, it makes no difference whether it is placed inside or outside the tank area; everyone is welcome to share their opinions.
Reply to 5# linaklee: It affects fire protection – how funny! How can fire protection be ensured in the tank area? Drive the fire truck in? The pipe gallery must lead into the tank farm; it is only necessary to lower its height when entering the tank farm. The pipe galleries inside the tank farm are generally referred to as pipe piers, with a height of around 300 to 500
Expert, I see it now clearly: if they raise questions, I’ll immediately ask them to show me that standard; if they can’t do that, then they’re worthless. Of course, I need to be polite.
Too many experts these days are just after cash gifts and cannot stand scrutiny.
It is possible to design and install pipe galleries or pipe piers within the tank area, but maintenance access paths must be taken into consideration
There are two scenarios: one is the inflow and outflow of pipes within the tank area, and it is best to use pipe ladders for this； Another option is for an external pipe gallery to pass through the tank farm, but this should be avoided if possible.
