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. WebPressure ratings are measured in pounds per square inch gauge (psig). Valve flanges are constructed of different materials, including steel, stainless steel, gray iron and ductile iron. As each of these materials offers a different strength, they each correspond with a different pressure rating. how to snorkel in sims 4
