Expansion Bellows

It is Inevitable to Install

Stainless Steel Expansion Bellows 


Hot exhaust gas causes pipes to expand. In order to absorb this expansion and protect the piping system against costly cracks that may damage the engine, it is inevitable to install expansion bellows.

The high quality SB Broneske standard expansion bellows have multiple layers, are pre-stressed, and come with two mild steel flanges (DIN 86044). Other flange materials and dimensions are available on request.

Our expansion bellows are type approved by Germanischer Lloyd. If certification from different class is requested it usually poses no significant problem to obtain this at additional cost.

Please note that SB Broneske does not stock expansion bellows as it is our engineering philosophy to always produce them according to our in-house engineering specifications with regard to lengths as well as axial and lateral movements.

The calculations / designs for the stainless steel expansion bellows are supplied free of charge.
