Conduit Shrink Calculator

Formula

To calculate the Conduit Shrink:

\[ CS = OD \times SPI \]

Where:

\( CS \) is the Conduit Shrink (in)
\( OD \) is the Offset Distance (in)
\( SPI \) is the Shrink Per Inch (in/in)

What is Conduit Shrink?

Conduit Shrink refers to the amount by which a conduit or pipe reduces in size due to thermal expansion, contraction, or other factors. It is calculated based on the offset distance and the shrink per inch. This measurement is essential for accurate installation and fitting of conduits in various applications.

Examples

Here are some examples of calculating conduit shrink:

For an offset distance of 10 inches and a shrink per inch of 0.02 inches/inch:

\[ CS = 10 \times 0.02 = 0.20 \text{ inches} \]

For an offset distance of 5 inches and a shrink per inch of 0.05 inches/inch:

\[ CS = 5 \times 0.05 = 0.25 \text{ inches} \]

FAQ

Why is conduit shrink important?

Conduit shrink is important because it ensures that the conduit or pipe fits accurately in its intended installation space, accounting for any changes in size due to environmental factors or material properties. Accurate calculations help in preventing installation issues and ensuring proper functionality.
