How do expansion joints contribute to conduit installations?

Expansion joints are crucial components in conduit installations as they allow for adjustments in length due to temperature changes. When temperatures fluctuate, materials can expand or contract. This movement can put stress on the conduit system, potentially leading to damage if there is no accommodation for these changes. Expansion joints are specifically designed to absorb this movement, ensuring the integrity of the installation remains intact.

They facilitate a streamlined and safe conduit run by pivoting or sliding as necessary, effectively managing the thermal expansion and contraction that occurs in response to environmental temperature variations. This prevents issues such as buckling or excessive strain on joints, which can lead to failure of the conduit system.

While other options may touch on related concepts, such as flexibility in connection length or aesthetic appeal, the primary and most critical purpose of expansion joints directly relates to their function in managing length adjustments caused by temperature variations.
