Copper in dry pipe system??

Copper in dry pipe system??

Copper in dry pipe system??

(OP)
I have a consultant that is requiring a dry system for an MRI room.  Typically, we do wet pipe CPVC or Copper in MRI rooms.  However, since this is a dry system, CPVC is out.  Is there anything prohibiting Copper tubing in a dry system?  Would I still use a C-150 for the calcs if it is permissible?

Thanks in advance for any help.

RE: Copper in dry pipe system??

do not have the book, but I think it is allowed

I found the information.  Thanks.  It is allowed.  You have to braze the copper and not solder.  Other than that, no real problems.  

I have just never encountered a dry pipe system using copper piping.

"I have just never encountered a dry pipe system using copper piping."

When you go to purchase the copper you'll know why.

But we do learn something new every day.  Thanks.

It's going to be a change order for my customer, so I am sure they will make decent $$ on it.
