UNION-TYPE BELLOWS

Union-type, or twin-sphere, bellows from Truco connect misaligned pipelines. Designed with a unique twin-sphere construction, this bellow facilitates greater flexibility in pipelines than regular, single-sphere bellows.

Compression moulded and joined by union heads and screw-in threads, Truco's union-type bellows absorb the elongation and contraction of steel pipes caused by variations in temperature and prevents the piping system from cracking.

Additionally, our union-type bellows reduce vibration and noise for all types of steel pipes.
