We have developed rectangular expansion joints with all kind of corrugation profiles for rectangular ducts. They can be made using either stainless steel 1.4541 or special alloys.
The expansion joints are distinguished by their large movement and small adjusting forces in conjunction with compact dimensions. They can be manufactured with either rounded or beveled corners. Rounded corners are more complex to manufacture, but permit larger movements per corrugation and have lower adjusting forces.
In addition to complete expansion joints with weld ends or flanges, we can supply expansion joints without connection parts for welding directly to the connecting ducts. if their dimensions are very large, they can be delivered dismantled and assembled on site.
