Flexible metal tubes are designed for versatility and durability in various electrical and construction applications. Here’s a detailed overview of their key characteristics:
- Flexibility
- Description: Flexible metal tubes are constructed with a helical metal strip wound around a core, which imparts exceptional flexibility. This design allows the conduit to bend and adapt to various shapes and routes, making it particularly useful for installations where rigid conduit systems would be difficult or impractical to use.
- Corrosion, Tensile, and Wear Resistance
- Description: The outer metal strip of flexible metal tubes is engineered to resist corrosion, tensile stress, and wear. This ensures that the conduit maintains its integrity and functionality even in harsh environments where mechanical damage or environmental factors could otherwise lead to degradation.
- High-Temperature Tolerance
- Description: The inner wall of flexible metal tubes is coated with an insulating resin layer that can withstand high temperatures. This coating is crucial for protecting electrical wiring in high-temperature environments, ensuring both the safety of the wiring and the proper operation of the conduit.
Location of Installation
Dry Applications
- Description: Flexible metal conduits are most commonly used in dry environments. Their flexibility allows for easy installation in tight or complex spaces, similar to rigid conduits. They are versatile and can accommodate various installation scenarios where bending and routing around obstacles are necessary.
Wet Applications
- Description: Standard flexible metal conduits are not suitable for wet conditions. However, there are versions designed with UV-resistant polymers that make them watertight. When installing in wet environments, it is essential to use appropriate liquid-tight fittings to ensure a secure and moisture-resistant installation.
General Installation
- Description: Flexible metal conduits can be installed in most locations where rigid conduits are used. Their ability to bend and adapt makes them ideal for installations that require routing around obstacles or making directional changes without the need for additional fittings or connectors.
Conclusion
Flexible metal conduits offer significant advantages for various installation needs due to their flexibility, durability, and resistance to environmental factors. They are particularly useful in applications requiring adaptability and protection while providing ease of installation. For environments where flexibility is advantageous and protection is crucial, flexible metal conduits are an effective and practical choice.
