Hi,
In a finished project, the vendor of plate and frames has chosen a unique design pressure and temperature and accordingly a unique hydrotest pressure for both hot and cold sides. In other words vendor has chosen the highest design pressure of either hot or cold sides and highest design temperature of either hot or cold sides for both. Does anyone know something about it? Is it a common practice to consider an identical design pressure and temperature for both sides?

Hi Ali,

 

For plate and frame heat exchangers, there should be separate Design Pressure/Design Temperature values for Hot/Cold sides hence separate Hyrotest pressure values for mentioned sides.
