Pipe Bend Weight Calculator

Formula

The formula to calculate the Pipe Bend Weight (PBW) is:

\[ PBW = 0.0387 \times T \times (OD - T) \times R / 1000 \]

Where:

\( PBW \) is the pipe bend weight (kg)
\( T \) is the thickness (mm)
\( OD \) is the outside diameter (mm)
\( R \) is the mean radius (mm)

What is a Pipe Bend Weight?

A pipe bend weight is defined as the total weight or mass required to bend a pipe to a 90-degree angle. This weight or mass, if multiplied by the acceleration due to gravity, would equal the force needed to bend the pipe.

Example Calculation

Let's assume the following values:

Thickness (T): 10 mm
Outside Diameter (OD): 100 mm
Mean Radius (R): 50 mm

Step 1: Calculate the Pipe Bend Weight (PBW):

\[ PBW = 0.0387 \times 10 \times (100 - 10) \times 50 / 1000 = 0.0387 \times 10 \times 90 \times 50 / 1000 = 1.7415 \text{ kg} \]

The pipe bend weight is approximately 1.7415 kg.
