ANG Angle Compensators

Angle expansion joints ANG compensate angular movements in one plane of the pipeline. 

As a standard, the bellows are made of steel of the 1.4541 (AISI 321) grade or, at the customer’s request, we make expansion joints with bellows made of 1.4304 (AISI 304) , 1.4404 (AISI 316L) steel. , 1.4828 (AISI 309) or other.

For technical reasons, we do not use S235 / St3S class steel bellows for the production of expansion joints. These types of expansion joints are made in a welded version, flanged 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.
