Dual Axial Corrugated Bellow Expansion Joint
The dual axial compensator is composed of two bellows connected by one middle pipe, rigid base connected to the middle section,and two flanges or end pipes in two ends. Each bellows compensates the displacement of each pipe section as a single ordinary expansion joint. The rigid connection between the base and middle section pipe can withstand all the forces and moments related to the application.
