Titanium Bellows Manufactured for Extreme Corrosion Service

Amines that are processed at the Union Carbide facility in Hahnville, Louisiana are very corrosive to most alloys that are typically used for expansion joints. Experience has shown that titanium is the best choice for the bellows in these severe service conditions.

The photo shows a 24” tied single expansion joint with titanium bellows furnished to the Hahnville facility. The expansion joint is designed for full vacuum to 76 psig at 300° F. The bellows is reinforced with carbon steel root rings to provide adequate pressure containment at the operating temperature. A titanium ring is welded to the bellows to form the gasket seating surface so that all wetted surfaces are titanium. The flanges are loose to rotate to facilitate fit up to the adjacent pipe flanges.
