WebThe flange rating or class refers to the maximum pressure that a flange withstands at the increasing temperatures. Flanges with a higher rating are stronger than the flanges with a lower rating, which means 600# flanges can bear more pressure than 150# flanges. But it totally depends upon the temperature range. Web1) Ratings are independent of the contained fluid and are maximum Non-Shock pressures at the tabulated temperatures. Intermediate ratings maybe obtained by linear interpolation between temperatures shown. 2) The temperature shown for the corresponding pressure rating shall be the material temperature of the pressure retaining structure.
