Rectangular Bellows with Flanged Ends

This rectangular bellows with flanged ends is designed for rectangular air duct systems. It features an additional sealing structure with a filled sealing layer. We have been manufacturing these products for twelve years. Our factory is located in Jiangyin Huashi Industrial Park. We operate a 3,000-square-meter facility with 24 skilled technicians.

We use multiple production lines and more than twenty metal processing machines. Our monthly production capacity is 4,000 pieces. We are ISO 9001 certified and comply with the GB/T 12777 standard. Third-party inspections are welcome.

This rectangular bellows with flanged ends provides significantly improved sealing performance compared with standard models.

The filled sealing structure provides this rectangular bellows with flanged ends with enhanced sealing performance. It helps reduce air leakage and prevents gas mixing between different areas more effectively than standard bellows designs.

It maintains full displacement compensation capability while reducing vibration and noise. It effectively absorbs thermal deformation. The design helps prevent dust accumulation and provides long service life.

The structure is strong and easy to install. It is especially suitable for applications with strict sealing requirements, such as dust collection systems and high-temperature exhaust systems.

Export products are packed in wooden crates. In dust collection systems, this rectangular bellows with flanged ends helps prevent dust leakage and supports compliance with environmental emission requirements.

For high-temperature exhaust ducts, this rectangular bellows with flanged ends provides reliable sealing performance and heat resistance. Its design helps reduce dust accumulation.

Waste incineration plants use this product in flue gas pipelines. The enhanced sealing performance helps reduce the risk of hazardous gas leakage.

Based on our experience, the filled sealing structure is recommended for applications requiring higher sealing performance. Standard rectangular bellows may not meet the requirements of these applications.

For long-term high-temperature operation, the temperature resistance of the sealing filler material should be considered. For wet flue gas environments, weathering steel is recommended for improved corrosion resistance.

The MOQ is 500 pieces. Delivery time is within 30 days. We provide a six-month warranty and respond to quality issues within 24 hours. Payment terms are 30% deposit and 70% balance before shipment.
