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. WebNov 6, 2024 · In general, ASME B16.47 Series A flanges are thicker, heavier and stronger than Series B flanges for the same size and pressure rating, and can therefore withstand more external loading than Series B type. From a commercial point of view this makes Series A more expensive than series B equivalents.
