What is pressure temperature rating of pipe fitting or flange? Factor which affect P-T rating? How the P-T rating selected as per ASME code?
The flange pressure temperature 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. As the … Read more
