How Do You Calculate Flange Weight?
The weight of a pipe flange depends on the material used in construction of the flange. It can also affect the pressure that the flange can handle. For example, if 304 ss is used for constructing the flange, then
Volume of pipe flange= π/4*(A1*A1－B1*B1－D1*C1*C1)*C(mm)
Density of 304ss = 7.93/1000000 Kg/cm^3
Therefore, weight = (A1*A1－B1*B1－D1*C1*C1)*C*π/4*7.93/1000000(kg)
How Is Welding Neck Flange Weight Calculated?
The Welding Neck Raised Face Flange is the most popularly used flange among all. The weight calculation for it is divided into two parts. One includes the short length of the pipe and the other is the truncated cone which gets deducted by the cylinder. Adding the two up, will give the weight of the weld neck raised face flange.
Formula 1: W =[(A1*A1－B1*B1－D1*C1*C1)*C+(X*X-A*A)*H]*6.228/1000000
Formular 2: W=[(A1*A1－B1*B1－D1*C1*C1)*C-(A1*A1-X*X-D1*C1*C1)*H]*6.228/1000000
How Do You Calculate The Area Of A Flange?
The formula to Calculate The Area Of A Flange is (3.142/4)*((o.d sq.- i.d sq.)*1.1)
