Calculate Pipe Pressure Rating





Formula

To calculate the Pipe Pressure Rating (\(P\)):

\[ P = \frac{2 \cdot s \cdot t}{D} \]

What is a Pipe Pressure Rating?

A pipe pressure rating is defined as the maximum amount of internal pressure a pipe can handle before it yields under stress. The pipe pressure rating is dependent on the wall thickness, the overall size (diameter), and allowable tensile or yield stress. The allowable tensile or yield stress is dependent on the type of material the pipe is made of.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ P = \frac{2 \cdot 3000 \cdot 0.4}{12} = 200 \]

The Pipe Pressure Rating is 200 psig.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ P = \frac{2 \cdot 2500 \cdot 0.5}{10} = 250 \]

The Pipe Pressure Rating is 250 psig.
