Gooch Thermal spiral heat exchangers are designed and built to ASME Code with U-stamp and registered with the National Board.

Our engineering and manufacturing services include inspections, failure analysis, and vessel repairs under our NBIC "R" Stamp.

Certificates of Authorization

  • ASME “U” Stamp
  • National Board “NB” Stamp
  • National Board “R” Stamp

In Canada, we comply with the Canadian Registration Number (CRN) requirements for all of the provinces and have many spiral heat exchangers in Alberta registered with ABSA.

We can also supply spirals built to other internationally recognized pressure vessel codes.
