Dear all,
I am working in an EPC company for refinery heater. I am now working on a revamping project for which I have an small issue.
We are going to manufacture a new furnace and it will replace the existing one. That means, the we are going to connect our furnace on the existing process line (done by flange).
On the plant drawings I have in my hands, it seems that flanges from client side is defined as ISO PN 100 DN 150 for example.
It seems that flange defined by ISO PN or only by PN are not exactly the same. I have to define the flange of my furnace and my main question is my flange will be EN or ASME Flange.
Does anyone know if ASME & EN flanges can be assembled together without any issue ? or should I respect ASME-ASME Flange or EN-EN Flange combination ?
For my case ISO PN is a demomination for ASME or EN Flange ?
Thank you in advance,
Best regards,
Flo
