How do you calculate the weight of a flange?

How to calculate the weight of pipe flanges?

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