Forged steel flanges, according to ASME B16.5, are made in seven primary ratings:
Class 150 - 300 - 400 - 600 - 900 - 1500 - 2500
The concept of flange ratings is relatively simple. A Class 300 flange can handle more pressure than a Class 150 flange, because a Class 300 flange are constructed with more metal and can withstand more pressure. However, there are a number of factors that can impact the pressure capability of a flange.
The Pressure Class or Rating for flanges will be given in pounds. Different names are used to indicate a Pressure Class.
For example: 150 Lb or 150 Lbs or 150# or Class 150

I think the reason behind all those increase in number bolts, thickness, etc is to make the flanges stand Higher pressure

Exactly. When doing blowdowns rupture test certain flanges is required for testing

What does it mean to ‘rejoint a flange’?

@LakhwinderSingh-rm7mf 4 жыл бұрын

Please anyone could tell me why we use 2mm raised face height in class 300 and 6.4 mm in class 600 and above?

@feonor26 Жыл бұрын

Same reason as to why the the rest of the flange is thicker in the 600 class compared to 300. It has to withstand higher pressure. When you scale up from class 300 to 600 you have to add material proportionately.

The biggest mistake is calling classes as "pound". Class numbers have nothing to do with pound. Check ASME codes. Its the biggest mistake in the field and people easily get confused thinking 300 "pound" means its designed to withstand 300 psi.

@feonor26 Жыл бұрын

I am aware of this mistake, but I never truly fully grasped what exactly does 300 "pound" mean in this case? Can you elaborate?

@MrHELLKEEPR Жыл бұрын

@K H Confusion is due to how they named these classes. Always consider "150" pound class just a name for the lightest standard flange. Next is 300, 600 etc. How much pressure a flange can withstand is dependent on flange material and temperature of fluid. For instance, 150# carbon steel flange used for water at 212F can withstand approx 250psi. And 300 class can withstand 740psi for same temperature while 400 class would go upto 1000psi. And similarly for higher working temperatures there ratings would be much lower. For example, class 400 CS flange at working temperature of 1000F is only good for approx 115psi.

@@MrHELLKEEPR Good god, 1000F? That's 530 degrees C. What kind of system or piping facility do you meet those kind of temperatures? Thanks for the answer tho.
