Air Flue Duct Expansion Joints Fabric from Beijing Zhonghaiwei Environment Engineering Co. Ltd. combines rubber flexibility with glass-fabric heat resistance, featuring metal spool and flange connections for integration with wind machines and air ducts. The design compensates for thermal expansion and multi-directional displacement in duct systems while reducing noise and vibration transmission from boilers, wind machines, and air currents through sound absorption and vibration isolation properties.
The fabric expansion joint is built for desulfurization applications, offering high strength, tightness, and corrosion resistance with a simple structure and long service life. It uses rubber and glass-fabric materials to ensure medium resistance and air impermeability, with typical industry applications including power plants, metallurgy, and cement kilns. Standard configurations often include a multi-layer fabric belt with a typical thickness range of 3 to 6 mm, depending on pressure and temperature requirements.
This product is adopted in large and medium-sized desulfurization projects across China, particularly in flue gas systems for boilers, gas turbines, and dust collectors. Buyers include power generation plants, steel mills, and cement manufacturers sourcing for fume extraction and ventilation systems. The joint requires minimal installation space and adapts to existing conditions, with proven performance in reducing heat loss through insulation and maintaining a cool outer layer for on-site safety.

Before ordering, verify the expansion joint’s compatibility with your duct system’s temperature and pressure ranges. Request the supplier’s technical data sheets to confirm material specifications, such as the rubber and glass-fabric composite’s tolerance to your operating conditions. Check for any additional coatings or treatments applied to enhance corrosion resistance.
Confirm logistics details, including lead time, packaging, and Incoterms. Fabric expansion joints are typically shipped as flat-packed or rolled units, so discuss handling requirements to avoid damage during transit. Clarify whether the supplier provides flange adapters or if these must be sourced separately to match your ductwork. Payment terms should align with your procurement policies, with options like TT or LC commonly used for bulk orders.
Quality checks should include visual inspection for fabric integrity and proper flange alignment. Request third-party test reports for pressure and temperature resistance if not provided. For desulfurization applications, ensure the joint meets industry standards for corrosion resistance, such as ISO 2812 for chemical exposure testing. Inspect the metal spool and flange connections for proper sealing to prevent leaks in the duct system.
