I can't send a private message. Please fill out your information in this URL https://www.munichre.com/HSB/service-request/index.html and ask for Fred. I will make sure you get a complete answer on the ASME Stamp requirements.

J,
The ASME stamp requirement depends on a number of things like design and the jurisdiction of where the heat exchanger will be installed. I was just at the National Board of BPV in Columbus, OH and they had ASME U stamp plate heat exchangers in their training facility. I'd love to discuss...
Hartford Steam Boiler's Technical Data Handbook is a nice thing for pressure vessel engineers and fabricators to have.
