## What is the pressure rating of a 300 lb flange?

the class 300 flange (bigger and stronger, but with the same bore size) withstands 570 psi at the same temperature of 600 degrees F° finally, a class 2500 flange of the same size bears 34 times more pressure than the class 150 rated flange, reaching a whopping 4730 psi rating at 600 F°!

**How do you calculate the weight of a flange?**

How to calculate the weight of pipe flanges?

- Pipe flanges are used to connect pipe sections to other pipe sections, inline components, and equipment.
- 1.The materials used to construct a pipe flanges directly relate to the weight and the pressure it can handle.
- Pipe flanges volume=π/4*A1*A1－B1*B1－D1*C1*C1)*C(mm)
