KU Universal compensators
Universal KU expansion joints eliminating shifts in all planes.
As a standard, the bellows are made of steel of the 1.4541 (AISI 321) grade expansion joints with bellows made of 1.4304 (AISI 304), 1.4404 (AISI 316L), 1.4828 (AISI 309) or other steel. For technical reasons, we do not use steel class steel bellows for the production of expansion joints. S235 / St3S .
These types of expansion joints are made in welding, flange or mixed version (with two different connections). We also make expansion joints with one or two reducers (reductions) in case of changing the diameter of the pipeline.
