Stainless steel reducers

Stainless steel reducers in concentric and eccentric design

With a reduction, two different nominal widths are connected to one another in a pipeline. In our warehouse, we have a large range of stainless steel reductions in concentric and eccentric design. In the case of concentric reductions, the wall follows a straight, and in the case of an eccentric an oblique circular cone. Pipes equipped with eccentric designs can be more easily installed on foundations. Concentric designs, on the other hand, are better in terms of flow technology.

Stainless steel reducers made of a variety of materials

Our warehouse program includes articles made of many different materials, for example stainless steels such as 1.4539 / 904 L, 1.4571 / 316 Ti and 1.4404 / 316/316 L as well as many others. Duplex steel (1.4462) and Super Duplex steel (1.4410) are also available in our warehouse. In addition, we offer a wide range of products of heat-resistant and non-rusting stainless steels, as well as nickel base alloys and unalloyed or alloyed steels.
