Double Axial Bellows Expansion Joint

This double axial bellows expansion joint is designed for straight pipeline systems. It combines two bellows units into one structure to provide greater axial compensation capability. Our factory has been manufacturing these products for twelve years. We are located in Jiangyin Huashi Industrial Park. Our 3,000-square-meter facility employs 24 workers.

We operate two bellows forming machines 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 double axial bellows expansion joint is specially designed to absorb axial displacement. It provides two to three times greater compensation capability compared with a single bellows expansion joint.

This double axial bellows expansion joint features a stable structure and high rigidity. It absorbs thermal expansion in pipelines while reducing equipment vibration and pipeline stress. It provides reliable sealing performance and operates effectively under high and low temperature conditions.

The structure offers good corrosion resistance and fatigue resistance. Installation is simple and requires minimal maintenance. This double axial bellows expansion joint mainly absorbs axial movement and does not generate significant lateral reaction forces, helping maintain stable pipeline operation.

Export products are packed in wooden crates. Long-distance buried heating pipelines use this double axial bellows expansion joint because its large compensation capability meets the thermal expansion requirements of long pipeline sections.

In chemical plants, this double axial bellows expansion joint is suitable for long straight pipeline sections. It absorbs large axial displacement and helps reduce the number of fixed supports required.

Central heating primary networks also use this product. After installation, it requires minimal additional maintenance.

For selection, we recommend this double axial bellows expansion joint when axial compensation requirements exceed 100 mm. For applications involving lateral displacement, a double hinged or universal expansion joint should be considered. If installation space is limited, please confirm the overall product length in advance.

The MOQ is 500 pieces. Delivery time is within 30 days. We provide a six-month warranty.
