Lens expansion joints

Lens expansion joints are single-walled metal expansion joints in single or multi-shaft variations with lower expansion and very robust construction. These consist of one or several semi-circles that are welded into corrugation peaks and troughs with circular seams.


Lens expansion joints can be constructed in all types of stainless steel and in material thickness 1,5-6 mm.
Other dimensions and materials can be discussed upon request.

The construction parameters are as follows:

  • Diameter: up to DN 500
    Larger dimensions can be discussed on request.
