R406 application

Hello ....

I wondering if you can help me in the following situation :
we use the refrigerating gas R406A , but not for refrigerating , we use it as blowing agent in foam industry ......

So any one have an idea about the suitable pipe type for this gas , since the required pressuer in the pipe is : 12 bar , also about the pump (outdoor pump)


thanks in advance .....

We use a Van Steemburg recovery system that is slightly modified to flush our refrigeration systems with this. A common blowing agent used these days is R245fA by honeywell.
