DOUBLE EXPANSION JOINT, NO O-RINGS (ID) - ABOVE GROUND
The Double Expansion Joint (ID) is a high-performance, precision-engineered component designed to provide superior flexibility and expansion control in above-ground conduit systems, making it an essential solution for long conduit runs exposed to frequent temperature variations. Commonly known as a back-to-back expansion joint, this fitting plays a critical role in maintaining the structural integrity and durability of conduit installations by effectively compensating for the natural expansion and contraction that occurs due to fluctuating environmental temperatures. By allowing for these movements, it helps prevent the system from experiencing stress or damage, ensuring the conduit remains properly aligned and intact over time. This joint is particularly valuable for applications that require seamless management of thermal changes over large distances, as it enhances the overall reliability and longevity of the conduit system, even under the most demanding conditions.
Applications:
- Above-Ground Conduit Installations: Ideal for use in conduit systems that are exposed to environmental temperature changes.
- Extended Conduit Runs: Perfect for applications with long, continuous conduit spans where expansion control is needed to maintain structural integrity.
- Utility and Infrastructure Projects: Widely used in industrial, utility, and infrastructure settings to protect against temperature-induced damage.
Key Features:
- Double Expansion Capability: Provides enhanced movement accommodation compared to single expansion joints, making it suitable for complex or extensive runs.
- ID-Sized Conduit Compatibility: Designed for easy integration with ID-sized conduits, ensuring a snug and secure fit.
- Yellow Line Indicator: Features a yellow line on the nipple end for precise installation and alignment, reducing the risk of improper setup.
Benefits:
- Reliable Expansion Control: Prevents damage to the conduit system by allowing controlled expansion and contraction.
- Durable and Long-Lasting: Built to withstand temperature variations and environmental exposure, ensuring longevity.
- Simplified Installation: The yellow line indicator aids in correct orientation and proper setup.
- Adaptable Solution: Suitable for above-ground installations that require consistent performance over long distances.
