Joseph Oat Maintains an NBIC R Stamp for Repairs and Alterations. Using this authorization we are able to perform rerating calculations and stamp existing pressure vessels for new design conditions, compliance with updated Code years or accommodations to as-inspected conditions. In addition to Code rerating services, Joseph Oat can perform heat transfer, pressure drop and vibration calculations on existing heat exchangers.

All of the tools that are available for design and analysis are available for your rerating needs. To further aid the evaluation of existing equipment, Joseph Oat maintains complete records for all the custom equipment that we have fabricated over nearly the last 50 years.
