EJMA Standard Stainless Steel Dual Axial Corrugated Bellow Expansion Joint

Our dual axial expnasion joint works in the same way a hinged expansion joint does.It utilizes the ability of a bellows to rotate in angular direction.The axial movement capability is the result of the angular rotation of the bellows and their center to center distance. The longer the distance between the bellows, the larger is the movement capacity.

Product Description

Product Description

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.
