The Flue Non-Metallic Expansion Joint is a flexible connector designed to absorb thermal expansion, mechanical vibration, and installation misalignments in flue gas systems. Made from multi-layer, high-temperature, and corrosion-resistant non-metallic materials, it is widely used in power plants, metallurgy, cement, chemical industries, and more. This product effectively compensates for pipeline displacements, reduces noise and vibration, and extends equipment lifespan.
