Pressure and temperature boundaries are the most common violations we see in this boundary category. Don’t forget that pump suction pressure is part of the overall discharge pressure calculation.
Note: Allowable pressure limits decrease with increasing temperature and not all materials have the same ratings.
If there is any doubt please consult with us. We can send you a rating chart for both 150 and 300 class flange ratings.
Do not get a ticket from the boundary police.
